Director, Laboratory of LEGEST, University of Gent, Belgium. E-mail: [email protected] Inflammatory diseases are wide spread among human mankind. Although these various affections appear different according to the tissue affected, they have some general aspects in common, such as the production of inflammatory cytokines, like Interleukin-6 (IL6) and others. Actually, IL6 is a pluri-potent cytokine, of which the expression needs to be tightly regulated in order to keep the organism in a balanced and homeostatic condition. The IL6 gene is induced by a dual activation scheme: i.e. 1) the cytoplasmic activation of the general stress factor NF-kB, which after stimulation migrates to the nucleus and occupies its position on various gene promoters, and 2) the activation of the nuclear kinase MSK1, that phosphorylates the NF-kB p65 subunit at Ser 276 (to generate a fully transcription-competent enhanceosome), as well as the Histon-3 tails at Ser 10 (that is the onset of chromatin relaxation). Glucocorticoid hormones (GCs) remain the mainstay for the treatment of various inflammatory disorders, because of their great efficacy. The long-term usage of GCs is, however, overshadowed by the occurrence of debilitating side-effects, like osteoporosis, skin and muscle atrophy, diabetes and neurological disorders. GCs exert their functions through binding to the glucocorticoid receptor (GR), a transcription factor that regulates genes in a positive or negative way. Direct binding of activated GR in the promoter of target genes is believed to be the main pathway leading to metabolic gene expression (causing side-effects), whereas the interference of GR with the activity of other transcription factors, such as NF-kB or AP-1, greatly contributes to its desired antiinflammatory capacities. Dissociated ligands aim to separate GR-mediated transcriptional activation from transcriptional repression in order to achieve better side-effect profiles. Plant extracts have been used for many centuries as a popular remedy against several health disorders. In recent years, however, a renewed interest in folk medicine and herbal treatments is seen, and at present, the healing capacities of plant-derived compounds are being analysed at the cellular and molecular level. We have studied the molecular properties of a compound derived from the Withania species, growing in Palestine and used by the migrating shepherds in the desert. The major compound of the extract (Withaferin A) is a particular inhibitor of the activation pathway of NFkB, i.e. the main transcription factor for inflammatory gene expression and cell survival. This compound was shown to strongly exhibit anti-inflammatory capacities, both in vitro (cell 29 FAPRONATURA 2009 Second International Symposia on Pharmacology of Natural Products Varadero, Cuba. June 3-7, 2009 http://www.scf.sld.cu Revista Cubana de Plantas Medicinales vol. 14 (Suplemento Especial):30, 2009 cultures) and in vivo (mouse). Current efforts for its usage include the specific killing of malignant cells, which may be superior than chemotherapy or radiation therapy. A stabilized compound (CpdA), originally derived from a shrub (salt bush) in the Kalahari deserts of South-Africa and Namibia, has anti-inflammatory properties in vitro (i.e. in cell culture) as well as in vivo (mouse and rat). Furthermore, CpdA displays ‘dissociated’ activities, thus repressing inflammatory gene transcription but not stimulating steroid-driven gene expression. Compared to treatment with classical glucocorticoids, CpdA may avoid the harmful side effects of cortisone and thus give a better ‘benefit-to-side effect’ ratio than the presently used steroidal drugs. Moreover, CpdA does not lead to GC resistance, after prolonged treatment, like GCs do. OL-03 PHARMACOGENETICS OF HERBAL MEDICINE: POTENTIAL RELEVANCE VULNERABILITY TO DEPRESSION AND ANTIDEPRESSANT DRUG EFFECT. FOR Adrián LLerena*; Pedro Dorado; Eva M. Peñas-LLedó. Clinical Research Centre. Extremadura University Hospital and Medical School. Hospital Infanta Cristina, Badajoz, Spain. www.cicab.es [email protected] Herbal medicines are frequently used in combination with commercially available drugs, therefore interactions may occur. These potential herb-drug interactions may occur at pharmacokinetics as well as at pharmacodynamic phases. Drug-metabolising enzymes or transporters are involved in many herb-drug interactions, mostly due to competitive interaction at cytochrome P450 system. Polymorphisms in cytohrome P450 and transporters genes are related to the pharmacokinetic interactions. Secondly the potential interactions at pharmacodynamic level should also be considered for some drugs. Among drug metabolizing enzymes CYP2D6 is the most studied and clinical relevant for worldwide clinically used drugs (LLerena et al.; 2009). For example the effects of commonly used herbal products (Ginkgo biloba, kava, garlic, evening primrose oi, and St. John's Wort) on the catalytic activity of cytochrome P450 isoforms (CYP1A2, CYP2C9, CYP2C19, CYP2D6 and CYP3A4). It was shown herbal products containing could potentially inhibit the metabolism of co-administered medications whose primary route of elimination is via cytochrome P450, and thus may produce relevant clinical drug interactions (Zou et al.; 2002). Moreover the patients perspective might be relevant, since they considered regular prescription drugs to be more effective and more prone to adverse effects than herbal drugs. In this respect it has been shown that health professionals often overlook patients' use of herbal drugs (Wallerstedt et al.; 2005). Herbal medicine it is associated with certain cultures. Thus, taking into consideration that some genotypes may present variability across countries and ethic groups, the interethnic variability in herbal medicine should be a major issue in Clinical Pharmacogenetics. Currently, the pharmacogenetics approach has been used mainly to study drug-drug interactions, however taking into consideration the increase use of herbal medicine, not only in undeveloped world but also in so called “industrialized” countries the study of potential herb-drug interactions might be necessary in clinical pharmacogenetics (Dorado et al.; 2005). Variability in drug metabolism is mainly determined by genetic factors, however the importance of environmental (such as dietary, smoking, diseases etc.) and physiological factors has been also increasingly recognized (LLerena et al.; 1995). Moreover, there are suggestions that drug-metabolizing cytochrome enzymes (CYPs) may be involved not only in xenobiotic metabolism (drugs and herbs) but also in the biotransformation of endogenous substances and therefore it has been demonstrated its relationship with personality in Spanish and well as Cuban healthy volunteers (LLerena et al.; 2003, González et.; 2008). Moreover due to the CYPs expression in the human brain, it can be hypothesized the potential relationship to normal psychological and/or abnormal psychopathological processes including neurocognition (Peñas-LLedó et al.; 2009). Therefore, the use of herbal products might be related not only to drug efficacy but also to the disease pathophisiology. This is due to the role of pharmacogenetics factors (metabolism, transporters receptors etc) not only in relation to xenobiotic but also in relation to endobiotic metabolism and effect. For example CYP2D6 and CYP2C9 has been related to the metabolism of the antidepressant drug fluoxetine but also to depression (LLerena et al.; 2003 and 2004), therefore the potential interaction of herbal drugs (i.e. St. John's Wort, also metabolised by CYP2D6) may be clinical relevant at both disease mechanism and antidepressant drugs effects.

VIERNES, 5 de junio / FRIDAY, June 5 CONFERENCIAS / LECTURES (L) L- 05 COGNITION-ENHANCING EFFECTS OF GINKGO AND GINSENG. Scholey, A & Stough, C. National Institute of Complementary Medicine (NICM) Collaborative research Centre in Neurocognition and Natural medicines, Brain Sciences Institute, Swinburne University PO Box 218 Hawthorn, Victoria, 3122 AUSTRALIA E-mail: [email protected] There is a wealth of research indicating that ginkgo biloba and ginseng may have cognition-enhancing effects. This paper will briefly review evidence from double-blind, placebo-controlled human trials of the efficacy of a Ginkgo biloba and Panax ginseng alone and in combination as cognitive enhancers in various populations. Studies of the acute neurocognitive effects of standardized extracts of Ginkgo and Ginseng in healthy young adults revealed that the combination was a more effective memory enhancer than either extract in isolation. Furthermore a ginkgo-ginseng combination increased performance during heavily-loaded cognitive processing in a synergistic manner that could not be predicted from the effects of either extract alone. Other studies have revealed positive neurocognitive effects of a Ginkgo-Ginseng combination following chronic dosing in certain populations. These findings also illustrate some of the issues and challenges involved in conducting clinical trials into the neurocognitive effects of herbal extracts. 31 FAPRONATURA 2009 Second International Symposia on Pharmacology of Natural Products Varadero, Cuba.

National Institute of Complementary Medicine (NICM) Collaborative research Centre in Neurocognition and Natural medicines, Brain Sciences Institute, Swinburne University PO Box 218 Hawthorn, Victoria, 3122 AUSTRALIA. e-mail: [email protected] Bacopa monniera or brahmi has been used for centuries in India to improve cognitive functioning. More recently there has been an explosion of in vitro and in vivo animal research focusing on its neurochemistry and mode of action. In this presentation we discuss research on the Indian natural medicine brahmi in both animals and in human trials assessing neurocognitive functioning. We start off with a brief discussion of the mechanisms of action of brahmi generating hypotheses about its action on the human brain and on human cognition/ intelligence. A review of available human clinical trials including their samples, outcome measures and conclusions is then presented. We conclude the presentation with a discussion of future applications and trials with this interesting natural medicine. L- 07 MEMORY ENHANCING EFFECT OF BACOPA MONNIERA. Hemant K. Singh, Ph.D. (ex-Deputy Director, Central Drug Research Institute, Lucknow). Lumen Marketing Company 2, First Cross Street, Second Avenue, Ashok Nagar, CHENNAI - 600 083. E-mail: [email protected] Bacopa monniera has been used as a nerve tonic since Vedic civilization (c. 1500 B.C.). It has been frequently mentioned in WHO recognized Ayurvedic treatises as treatment of choice for various brain and specially memory disorders. Because of its unique pharmacological properties, the plant attracted attention of several researchers in India. A systematic chemical, pharmacological and pre-clinical investigations on this plant was undertaken by the Central Drug Research Institute, Lucknow. Chemical investigations showed that bacosides A and B are the main constituents of the plant, of which bacoside A is the predominant. Bacoside A was further shown to be having different moieties of bacogenins. A standardized extract of the plant containing an optimum concentration of bacosides vis-a-vis memory enhancing effect was developed. The extract was found to be significantly improving acquisition, consolidation and retention of newly acquired learning behaviors in variety of responses. It also attenuated pharmacologically induced amnesia in several animal models. The extract was found to be equipotent to Gingkgo biloba in enhancing memory and had significantly pronounced anti-stress and adaptogenic effects as compared to ginseng. This standardized extract also showed significant anti-oxidative and neuroprotective effects. The extract was found to be safe in acute and sub-acute (90 days) regulatory toxicity studies. Clinically it showed significant improvement in memory parameters in children (6-13 years), adults (25-55 years) and elderly (56-75 years) human volunteers in several learning parameters. It was found to be safe, well-tolerated and devoid of any significant side effect. 32 FAPRONATURA 2009 Second International Symposia on Pharmacology of Natural Products Varadero, Cuba.

Agriculture Building, Newcastle University, Newcastle upon tyne NE13GPF, UNITED KINGDOM E-mail: [email protected] Alzheimer’s disease (AD), the most common form of dementia is characterised by cognitive dysfunction and in most cases associated behavioural and psychological symptoms such as depression, agitation, stress and anxiety, which may lead to institutionalisation. Two of the current prescription drugs for dementia are acetylcholinesterase (AChE) inhibitors derived from plants. Galantamine was originally from Galanthus and Narcissus species and rivastigmine is based on the chemical structure of physostigmine from Physostigma venenosum. There is clinical evidence relating to cognitive enhancement for other plants including extracts from the European sage (Salvia officinalis), lemon balm (Melissa officinalis), the Indian herb Brahmi (Bacopa monniera), and for some complex mixtures of traditional Chinese / Japanese medicines, Ginkgo biloba, and the AChE inhibitor huperzine A from the moss Huperzia serrata. Both M. officinalis and Lavandula angustifolia alleviate agitation and there is unexplored potential for other plants to alleviate symptoms, such as Hypericum perforatum for depression and Valeriana officinalis for anxiety and sleep disorders. The potential application of these species for dementia therapy is examined from the joint perspectives of traditional medical uses, relevant mechanistic bioactivities and clinical controlled trial evidence. In addition epidemiological and related evidence for the value of plant based agents such as nicotine and curcumin, red wine or fruit and vegetable juices for prevention is reviewed. L-09 PANAX GINSENG (G115) IMPROVES ASPECTS OF WORKING MEMORY PERFORMANCE, MOOD IN HEALTHY YOUNG ADULTS. Reay JL1, Kennedy DO1, Scholey AB2 1 Brain Performance and Nutrition Research Centre, Northumbria University, Newcastle upon Tyne, UK, NE1 8ST. 2 Brain Science Institute, Swinburne University, Melbourne, VIC 3122, Australia. The term ‘Ginseng’ usually refers to the dried root of several species in the plant genus Panax (Araliaceae family). With regards to human trials, several acute studies have shown that 200mg of the standardised extract G115 is capable of reducing the subjective increase in mental fatigue associated with effortful cognitive processing and improving mental arithmetic performance (Reay et al., 2005; 2006). Additionally, a series of studies have reported improved memory performance following a single dose of G115 in healthy young volunteers (see Kennedy et al., 2003 for review). Despite growing empirical support for the beneficial effects following a single dose of G115, there is a lack of empirical research investigating the effects following repeated dosing. The present placebo controlled, double-blind, balanced- crossover study assessed the effects of 200 mg and 400 mg Panax ginseng (G115) and placebo on mood, secondary memory and aspects of working memory, following acute and sub-chronic (7 days) ingestion in healthy volunteers. Thirty healthy young adults (mean age 22.87 years; SD 4.01) received each of the treatments for 8 days, in counterbalanced order and with a 6 day wash-out between treatments. They completed a battery of tasks on the first (treatment with each of the three treatment condition Day 1) and last (Day 8) day of taking each treatment, at pre-dose and thereafter at 1hour, 2.5hours and 4hours post-dose. Results revealed acute effect; however, 7 consecutive days of G115 led to no additional additive effect. Planned comparisons revealed that 200mg was capable of improving subjective ratings of calmness on Day 1 and Day 8; whereas, the effect was restricted to Day 1 following 400mg. With regards cognitive performance, planned comparisons revealed an unexpected improvement following 400mg G115 (given that previous studies have shown 200mg to be the optimal dose) on some aspects of working 33 FAPRONATURA 2009 Second International Symposia on Pharmacology of Natural Products Varadero, Cuba. June 3-7, 2009 http://www.scf.sld.cu Revista Cubana de Plantas Medicinales vol. 14 (Suplemento Especial):34, 2009 memory. In conclusion, 200mg G115 modulates subjective mood, which may be associated with alleviating fatigue or stress that volunteers feel throughout the day; whereas, 400 mg appears to modulate cognitive function. More research is needed. L-10 - Presentación del Libro: Los retos de la Terapia Antioxidante. Colectivo de Autores.

García-Rivera D1, Vanden Berghe W2, Delgado R3, Haegeman G2. 1 Department of Center for Biomolecular Chemistry. Havana. Cuba. [email protected] 2 Laboratory of Eukaryotic Gene Expression and Signal Transduction (LEGEST), Department of Molecular Biology, Gent University. Belgium. 3 National Center for Clinical Trials. Havana. Cuba. Vimang is a natural Cuban extract popularly used as complement of cancer treatment; despite the molecular mechanisms of its possible antitumoural effects were still poorly studied. The aim of this study was evaluated the molecular mechanisms of action of Vimang, mangiferin and gallic acid (two of the main components) in the proliferation, gene expression and NFκB and MAPK-kinases pathway in MDA-MB231 breast cancer cell line. The methodologies used were Northern blot for proteins expression, ELISA for proteins quantification and RTQPCR for gene expression. The first evidence was the antiproliferative response showed after 48 hours of treatment with Vimang (IC50 259 µg/mL) and gallic acid (IC50 10 µg/mL), but mangiferin didn´t inhibit the proliferation of these cells. After TNF cellular stimulation, it was demonstrated the modulation of NFκB activation by Vimang (200 g/mL), mangiferin (100 µg/mL) and gallic acid (10 µg/mL). Three compounds inhibited the IKK phosphorylation, IkB degradation and interesting also reduced the IκB resynthesis. Then, p65 translocation into the nucleus and DNA-binding were reduced by the pretreatment with them. The treatment with Vimang, mangiferin and gallic acid reduced the expression of NFκB driven genes: IL-6, IL-8, COX-2 and VEGFA, and also reduced the IL-6 and IL-8 proteins levels. Vimang (200 µg/ml) and gallic acid inhibited the activation of the MAPKinases pathway, reducing phosphorylation in MEK1/2 and MSK-1, ERK1/2, p90RSK and S6. Mangiferin didn´t interfere with MAPK pathway. In summary, in this study has been identified a number of target molecules modified for the treatment with Vimang in metastatic breast cancer cells, which could be important in its application in the treatment of cancer. Also, it was demonstrated the contribution of gallic acid and mangiferin on these activities. L-13 CATECHOL CONTAINING POLYPHENOLS, MITOTOXICS OR MITOPROTECTORS?

However, when in the presence of Ca2+, mangiferin elicits mitochondrial permeability transition – MPT (Arch.Biochem.Biophys. 439:184-193, 2005), as evidenced by cyclosporin A-sensitive mitochondrial swelling. We propose that Ca2+ increases levels of mitochondria-generated ROS, which reacts with mangiferin producing quinoid derivatives, which in turn react with the most accessible mitochondrial thiol groups, thus triggering MPT. It seems probable that the free radical scavenging activity of mangiferin shifts its antioxidant protection to the thiol arylation. An interesting proposition is that accumulation of mangiferin quinoid products would take place in cells exposed to 37 FAPRONATURA 2009 Second International Symposia on Pharmacology of Natural Products Varadero, Cuba. June 3-7, 2009 http://www.scf.sld.cu Revista Cubana de Plantas Medicinales vol. 14 (Suplemento Especial):38, 2009 an overproduction of ROS, such as cancer cells, where the occurrence of MPT-mediated apoptosis may be a cellular defense mechanism against excessive ROS formation. We also provided evidence, by means of electrochemical and UV-Visible spectroscopical analysis, that Fe(III) coordinates with mangiferin. The resulting mangiferin-Fe(III) complex does not elicit MPT, and prevents MPT by scavenging reactive oxygen species. Indeed, the complex protects mitochondrial membrane protein thiols and glutathione from oxidation. Fe(III) also significantly increases the ability of mangiferin to scavenge the 2,2-diphenyl-1-picrylhydrazyl radical, as well as to display antioxidant activity towards antimycin A-induced H2O2 production and t-butyl hydroperoxide-promoted membrane lipid peroxidation in mitochondria. We postulate that coordination with Fe(III) constitutes a potential protective mechanism towards the prooxidant action of mangiferin and other catechol-containing antioxidants regarding MPT induction. We therefore envisage for mangiferin and perhaps for other cathechol-containing polyphenols, a potential use either in preventing or eliciting cell death, simply in connection with the availability of free/labile-bound iron in the cell environment. These circumstances should be taken into account during human polyphenol supplementation, for either the prevention or not of their prooxidant effects, as well as for optimization of their antioxidant performance.

Background: c-Phycocyanin (c-Pc), a natural antioxidant derived from the blue-green algae Spirulina platensis, has been reported to exhibit pharmacological properties such as the capacity to inhibit cyclo-oxigenase 2, the inflammatory processes and production of prostaglandin, leukotrienes and TNF-alpha, all of which may be expected to symptomatically improve Experimental Autoimmune Encephalomyelitis (EAE) and Multiple Sclerosis (MS). However, in this study we reveal a basic underlying mechanism that may provide an in-depth approach to the rationale of the overall beneficial effect of this natural biliprotein. Materials & Methods: PBMC from MS patients' were divided into four experimental groups: IFN-alpha treated cells, c-Pc treated cells, IFNalpha/c-Pc treated cells and untreated cells. Genes of regulatory T cells (Treg) markers were amplified and the CD4+CD25highFoxp3+ subset of different experimental groups was measured by flow cytometry. EAE model was developed in Lewis rat in order to assayed c-Pc effect. Clinical scores, oxidative stress markers and microscopic studies were evaluated. Results: We found that in PBMC from MS patients and healthy controls IFN-alpha/c-Pc provokes a CD4+CD25high+Foxp3+ rTc response. Moreover, we have found that c-Pc is able to trigger mechanisms preventing EAE expression or downgrades its symptom scale score. Transmission electron microscopy studies of brain samples also corroborated the improvement induced by c-Pc of the EAE myelin and axonal damage. Conclusion: These results show that rTc may be the main and the essential contributor to support the therapeutic potential of IFN-alpha/ c-Pc combination for MS treatment. Other autoimmune and neurological diseases could also benefit from these findings. 38 FAPRONATURA 2009 Second International Symposia on Pharmacology of Natural Products Varadero, Cuba.

Evangelina Marrero Faz, DrSc Grupo de Química, Farmacología y Toxicología Centro Nacional de Sanidad Agropecuaria, CENSA, Apdo. #10, San José de las Lajas, La Habana, Cuba. [email protected] Natural products (NPs) represent the most important source of new commercially viable drug leads because the chemical diversity and novelty associated with natural sources is higher than that of any other source. It is particularly important when searching for lead molecules against newly discovered targets for which there are no known small molecule leads. Regardless those mentioned advantages of NPs the industrial drug discoveries not always are enthusiastic to approach research projects. Despite the believed assumptions, NPs can be a more economical source of chemical diversity compared with synthesis of equivalent numbers of diverse chemicals. In addition, less than 10% of the world’s biodiversity have been tested for biological activity, so still there are many useful lead compounds waiting to be discovered from natural sources. Moreover, NPs that are found to be biologically active in pharmacological assays are generally small molecules with drug-like properties, it means capable of being absorbed and metabolised by the body. The challenge is how to access to the great chemical diversity. Several different strategies are emerging in the post genomic era where a good deal of research have been approached for a better understanding of the molecular mechanism involved in the signalling pathways of different diseases oriented to find new promising therapeutics agents, being NPs of major attention. Pharmacological studies to obtain new molecules that concerns different relevant diseases as cancer, type 2 diabetes, antimicrobials, among other, obtained from natural sources constitute a hopeful research field where the great biodiversity observed mainly in tropical countries is still waiting to be explored. The present work brings information and examples on different and valuable strategies that are emerging to explore the pharmacological activity and chemical structure on NPs in relatively short time comparing with that of classic methods: eg. the molecular mechanisms involved receptors PTP-1B, PPAR α/γ among other therapeutic targets associated to type 2 diabetes and related metabolic disorders. The specificity of the mechanism associated to particular pharmacological targets brings also the opportunity to investigate the pathogenesis of definite disease at cellular and molecular level and also offers the opportunity to establish the mechanism of action involved in the traditional use of medical plant. The in vitro evaluation of natural extracts oriented to obtain new active molecules constitutes a valuable tool for the screening of the biological activity in an appropiate therapeutic target battery. The bio-guided fractioning will help to find new promising molecules. L-16 REGULATORY FRAMEWORK FOR THE DEVELOPMENT OF NATURAL PRODUCTS. Rodríguez J National Coordinator Center of Clinical Trials. 200 St. between 19 and 21 St., Atabey. Havana City. E-mail: [email protected], Telephone: 271-83-31. Background: The use of the natural medicine for the treatment of the different illnesses has increased their use and importance in the international trade. In spite of this situation the data of security and effectiveness of a number of plants, their extracts, their active principles and the finished products are really poor. The requirements of quality, security and effectiveness that should complete these products for being marketed under their medical use are settled down by Regulatory Agencies of Medicines (RMA). Objective: To obtain an overview of the main regulatory approaches that governs the development of natural products. Methods: An exhaustive bibliographical search was carried out using as key words: Regulation - Products - Natural. The primary sources of information were: Web of the FDA, EMEA and IBERO-AMERICAN COUNTRIES, Web of the World Organization of the Health (WHO) and Databases (MEDLINE, CENTRAL BIOMED and HINARI). Results: As a result of the analysis of the information it was seen that the focus of the RMA regarding the control of these products differs of a country to other, because in some the phytomedicines are very established, 39 FAPRONATURA 2009 Second International Symposia on Pharmacology of Natural Products Varadero, Cuba. June 3-7, 2009 http://www.scf.sld.cu Revista Cubana de Plantas Medicinales vol. 14 (Suplemento Especial):40, 2009 while in other they are considered as foods and it is not allowed to sustain that they possess therapeutic qualities. Most of the underdeveloped countries have a great quantity of phytomedicines based on popular knowledge and with big lacks of legislative approaches to establish these products of traditional use as medications. Conclusions: Europe takes the leadership in the development of regulatory framework for the development of the natural products. With some exceptions most of the regulations in existence is directed to the control of herbal products and it doesn't stop the entirety of products conceived inside the natural medicine. Cuba has two regulations for the use of its natural products. L-17 UPDATE IN PRECLINICAL AND CLINICAL REGULATORY REQUIREMENTS IN CUBA. Dr. Diadelis Remirez Figueredo. National Centre of the State Quality Control of Drugs (CECMED). E-mail: [email protected] In the last decade there has been a global upsurge in the use of traditional medicine and complementary and alternative medicine in both developed and developing countries. Pre-clinical and clinical assays are essential to guarantee the efficacy and safety of natural products and are commonly requested by regulatory agencies to approve marketing of these products. This work describes important aspects about the art state of the regulatory status of herbal medicines in Cuba. The objective is to give an updating about preclinical and clinical assessment of herbal medicines in Cuba. The main toxicological assays and pharmacological activities to be tested in the evaluation of natural products will be discussed in this presentation as well as the importance of clinical trials in order to guarantee the safety, quality and efficacy of NHP, the main mistakes in Clinical Trials of natural products are explained. The market and the main challenges are analysed in the investigation of the phytomedicines as well as the tendencies in the growth of this attractive sector. The natural health products are considered a very important source for the health in Cuba. L-18 QUALITY MANAGEMENT SYSTEM FOR CLINICAL TRIALS WITH NATURAL PRODUCTS IN CUBA. Sandra Álvarez Guerra, S. National Coordinator Center of Clinical Trials (CENCEC). 200th St. / 19 and 21 Atabey. Playa. Havana. E-mail: [email protected], Telephone: 271-7397 ext. 107 The quality of the process of Clinical Trials carried out in the investigation to new products of natural origin constitutes a factor that guarantees to promoters safety and reliable results which influences in obtaining the registration. In Cuba, the National Coordinator Center of Clinical Trials offers services in the design and conduction of Clinical Trials; among those we can mention researches with products of natural origin. One way that guarantees process quality, is the implementation of a Quality Management System according to ISO 9001 standards. With this work we intended to describe the design and implementation of Quality Management System for clinical trials in our institution. This system included stages of Preparation, Planning, Communication and information, Application, Certification and Maintenance. There were two fundamental strategies: human capital and documental system, both of supreme importance to guarantee the correct implementation. Some tasks were executed that evidenced a significant advance in the personnel's formation, being reinforced the performance of the leaders in the organization, the work in team, the identification with the objectives, the trust and the mutual support, besides having a well structured documental system that supports all related to the documentation which is generated during a clinical trial according to what establishes the reference standard. The correct design and implementation of the quality management System allowed to reach a national and international certification that brought harnessed multiple benefits contributing to a better development of the clinical trials with natural products at national level. 40 FAPRONATURA 2009 Second International Symposia on Pharmacology of Natural Products Varadero, Cuba.

Central Pharmacological Research Unit. Carvajal s/n entre Agua Dulce y A, Cerro, Ciudad de la Habana, Cuba. [email protected] Introduction: people use widely medicinal plants to solve primary health problems in Caribbean countries. Our research unit has kept a close collaboration with TRAMIL (Regional Program for Applied Research and Education on Medicinal Plant Uses in Caribbean Countries) since II TRAMIL Scientific Workshop was held in Havana in 1988. We also have coordinated the Medicinal Plant Cuban Research Program (1988-2004) to incorporate medicinal plants in our National Health System. Pharmacological and toxicological applied research to validate traditional medicinal uses has some characteristics and challenges. The aim of this lecture is to expose our experience during 20 years. Materials & Methods: it was reviewed our published results and those included in TRAMIL´s Caribbean Herbal Pharmacopoeia during 1988-2008. Results: it is shown the results in pharmacological and toxicological studies in 30 different species. Most of toxicological experiments indicated that traditional uses were safe and a high number of them were validated in preclinical experimental models. Conclusions: our data indicate that there is a high percentage of traditional medicinal plant uses which may be supported with preclinical evaluation. L-21 NATURAL PRODUCTS, SINCE PRE TO POSTMARKETING. Jiménez G. Pharmacoepidemiology Development Centre. 44 Street, No 502 esq. 5ta Ave Miramar Playa CP 11300 E-mail: [email protected] Plants have been the primary source of food and medicine for people of every culture throughout the world. However, practitioners of traditional medicine need to be more aware of the problems of toxicity. Infrequent adverse drug reactions will not be recognized without the existence of a formal system of reporting negative experience. Physicians who have patients taking any particular medicinal plant should try to document negative experiences, in order to gather enough scientific information about the adverse effects of the herb. The renewed interest in the western world for plants used in traditional medicine, and the rapidly growing interest in developing countries to start research programs in this area have, unfortunately, not emphasized the great importance of taxonomic botany and documentation for such research. Often there is uncertainty about the identity of plants reported to cause an adverse reaction. The World Health Organization (WHO) and the Uppsala Monitoring Centre has established a project with the aim of attaining global standardization for herbal medicines. On the other hand Cuba has a National Regulatory Authority with a defined policy about the regulation of traditional medicine, which includes that information about the interactions between natural products and conventional drugs should be reported. Moreover, Cuba has a Center in charge of Pharmacosurvelliance for the 41 FAPRONATURA 2009 Second International Symposia on Pharmacology of Natural Products Varadero, Cuba.

La medicina herbolaria es una de las formas más antiguas de atención médica que ha practicado la humanidad. A través de la historia, se han utilizado las plantas en todas las culturas del mundo hasta nuestros días. En la actualidad existe una extensa documentación científica relacionada con el uso de las plantas para la cura de diversas patologías que van desde la indigestión hasta el cáncer y el VIH. Se considera que las plantas medicinales son aquellas especies silvestres, cultivadas o manejadas que han sido utilizadas por el Hombre en el tiempo al descubrir propiedades que ayudan al tratamiento o prevención de una enfermedad o padecimiento. Su uso puede ser de forma tradicional, fundamentalmente en infusiones y extracciones sencillas pero para lograr una correcta aplicación de la planta como droga se debe manejar y conocer adecuadamente su hábitat y la cantidad y calidad de los principios activos que posee. La Organización Mundial de la Salud hace notar que de los 119 fármacos derivados de las plantas, alrededor del 74% se usan en la medicina moderna de manera que se correlacionan directamente con los usos tradicionales que las culturas nativas les daban como hierbas medicinales. Es interés de mostrar la experiencia alcanzada por el Centro de Investigación y Desarrollo de Medicamentos (CIDEM) en el tema considerando el interés científico y técnico que se ha puesto en el uso de las plantas medicinales lo que ha permitido desarrollar recomendaciones apropiadas para su uso a través de productos fitoterapéuticos de calidad y seguros en su uso y que va desde su cultivo hasta su comercialización. 42 FAPRONATURA 2009 Second International Symposia on Pharmacology of Natural Products Varadero, Cuba.

R. Centro Nacional de Biopreparados, Biocen. Bejucal, La Habana. Cuba. E-mail: [email protected] Many substances of natural origin have been currently used as supplements or medicaments for prevention or therapeutic purposes, with defined characteristics in terms of its composition, action mechanisms and indication. These products give some protection against several diseases including micronutrient deficiency, (iron, zinc, folic acid, and vitamins), endocrine and immune disease. A few. Nature has an arsenal of products with active ingredients, which have been used to obtain the nutritional supplements, nutraceuticals, pharmaceuticals and others. Has been little studied the influence of food on the effectiveness of some drugs and even less the influence of drugs in the proper absorption and use by the body of nutrients that provide food. In this aspect of particular importance for example prolonged treatments with drugs that damage the gastric mucosa and thus the absorption of micro and macro nutrients, but are acquired through food or by the action of the drug itself is not adequately, resulting in either case deficiency states. Another example is the deficiencies in certain vitamins and other nutrients for abuse of laxatives. That's exactly where it comes the use of natural products that often diminish the appearance of these interactions. The natural elements can alter the pharmacokinetics of drugs through changes in absorption, as occurs with Trofin (antianemic of natural origin) and iron salts, where the hem group is presented in its natural form, potentializing by the gradient of amino acid that make this product better absorption and efficacy with minimal adverse effects compared with iron salts. Our conclusion is that natural iron drugs (Trofin) as well as not develop interactions with other drugs and foods, but, It is therefore important to know and continue to study possible interactions in the new formulation, between drugs and food in order to obtain the desired therapeutic effect. OC-02 ABSORPTION AND METABOLISM OF FLAVONOIDS AND THEIR METABOLITES López R. Pharmacy and Foods Institute. University of Havana. E-mail: [email protected] Dietary flavonoids, a class of semi-essential food components, have long been believed to exert protective effects against many diseases, in particular cardiovascular disease , cancer and neurodegenerative disorders. The biological effect of these polyphenols and their in vivo circulating metabolites will ultimately depend on the extent to which they associate with cells, either by interactions at the membrane or more importantly their uptake. This has been well supported by a myriad of studies examining potential sites and modes of action. This work summarises the current knowledge on the cellular uptake of flavonoids and their metabolites with particular relevance to further intracellular metabolism and the generation of potential new bioactive forms. The impact of membrane transporters as well as metabolic enzymes on the cellular availability of these phytochemicals is examined. 43 FAPRONATURA 2009 Second International Symposia on Pharmacology of Natural Products Varadero, Cuba.

Rodeiro Guerra, I. Department of Pharmacology, Center of Marine Bioproducts, Loma 37, Vedado, Havana City, Cuba. Today, several herbals have been screened as phytopharmaceuticals and many patients with different diseases take herbs in addition to conventional therapy. Between others, these patients are subjected to suffering the effects derived from the co-administration of the herb and conventional drug, which is very frequently to found in many cultures, including west world. Pharmacological interactions possibly derive from the modulation in expression and/or activity of two major pharmacokinetic disposition systems, namely cytochrome P450 (CYP) and the multidrug transporters where P-glycoprotein is identified as the major. Herbs used in the traditional medicine and compounds isolated from its have been identified as substrates, inhibitors or inducer of different cytochromes and/or transporters in humans. However, kknowledge about how natural products modulate its enzymatic systems, which may lead to lower therapeutic efficacy and/or adverse effects of conventional drugs, is limited. This works offers an overview of the knowledge about the interactions of these kinds of products and the drugs. Interactions of ginkgo, saw palmetto, hipericum, kava kava, ginseng, between other are revised. Effects observed after evaluation of different products used during several years in the traditional medicine in Cuba (Mangifera indica L., Thalassia thestudium, Erythroxylum species) are presented.The elucidation of these interactions may be important not only to predict possible undesirable effects deriving from the concomitant intake of herbal constituents and conventional drugs, but also for further studies of positive uses of these interactions as a way to increase the bioavailability of drugs that are P-gp substrates, as example. Physicians must be prepared to discuss traditional medicine use with their patients and to be aware of potential interactions without prejudices. OC-04 SAFETY OF CURCUMA LONGA L.

Firenzuoli, MD), S.Giuseppe Hospital, Az USL 11 Empoli, ITALY www.naturamedica.net E-mail: [email protected] Curcuma longa L extracts tritated in curcuminoids is a well known herbal based treatment for inflammatory diseases particularly of the gastrointestinal tract. We often administer to our patients Curcuma longa extracts for these types of pathologies and sometimes patients are contemporary assuming warfarin, a drug that has many interactions not only with other drugs but also many foods. In a consecutive series of 12 patients assuming different doses of warfarin and a stable INR, we adopted a protocol based on the administration for 2 weeks 500 mg of Curcuma longa extract tritrated at 95% in curcuminoids, and asking patients to underwent 3 controls of INR, and then in the following 2 weeks assuming a dose of 1000 mg of Curcuma longa extract and asking to repeat three controls of INR. In all patients INR remaind stable at the dose of 1000 mg too. We conclude nevertheless a small series, probably Curcuma longa extracts do not interfere with warfarin. 44 FAPRONATURA 2009 Second International Symposia on Pharmacology of Natural Products Varadero, Cuba.

Canada. V5A 1S6. E-mail: [email protected] 2 School of Pharmaceutical Sciences, Sun Yat-Sen University, 132 East Circle, University City Guangzhou, Guangzhou, China, 510006. Theophylline (TP) is a bronchodilator with a narrow margin of safety. Co-administration of TP and caffeine may lead to an increased TP bioavailability in human due to competitive inhibition of drug metabolism involving the hepatic CYP1A isozymes. In the present study, the physiologically based pharmacokinetic (PBPK) model of TP was used to estimate an in vivo inhibition constant (Ki) of caffeine on TP metabolism and to predict the toxicity of different TP dosing regimens in human with and without daily intakes of coffee and dietary caffeine. The PBPK model was adapted from Ginsberg et al., (J. Toxicol. Environ. Health. 67: 297, 2004) and consisted of 5 flowlimited compartments including the liver, fat, richly perfused tissue, slowly perfused tissue, and blood. A modified Michaelis-Menten equation was used to describe the competitive inhibition of TP metabolism in the liver. The PBPK model was calibrated using the experimental data of Sato et al. (Eur. J. Clin. Pharmacol. 44: 295, 1993) and found to simulate closely the kinetic data of caffeine-free adults after administering a single oral TP dose (5.3 or 7.5 mg/kg). The PBPK model was optimized to obtain the “best-fit” Ki value based on the experimental data of human drinking 2-7 cups of coffee daily. The model-optimized Ki value, 7 µg/ml was much smaller than the 134 µg/ml Ki value reported previously using human liver microsomal preparations. The PBPK model also was used to predict the risk of adverse reactions in adults after receiving multiple TP doses (340 or 450 mg b.i.d.) with the usual intake of coffee and dietary caffeine. The simulation results showed that only the subjects treated with the 450 mg dose had blood concentrations higher than the 20 µg/ml toxic TP level. The PBPK model represents an innovative and useful approach of studying drug/coffee interaction in human. OC-06 HERB-DRUG INTERACTIONS? DRUG COMPANY HYSTERIA OR COMMUNITY CONCERN? Stough, C National Institute of Complementary Medicine (NICM) Collaborative Research Centre in Neurocognition and Natural medicines, Brain Sciences Institute, Swinburne University PO Box 218 Hawthorn, Victoria, 3122 AUSTRALIA e-mail: [email protected] The incidence of consumption of herbal medicines throughout the western world is significantly increasing. In response to this changing incidence has been the identification of potential herbal medicine-drug interactions. Strong claims have been made in the popular press about the safety of herbal medicines and various international governments and international health bodies have made statements relevant to this topic. In this talk I discuss the hysteria behind this phenomenon. I outline the research that has been conducted in this area and describe the evidence for potential problems and therefore the validity of current claims. I outline some recent examples and describe a basic framework to evaluate the health risks of herbal medicine-drug interactions in the future. 45 FAPRONATURA 2009 Second International Symposia on Pharmacology of Natural Products Varadero, Cuba.

The use of natural antimicrobial systems for the preservation of foods is increasing. An example of a natural preservative agent is carvacrol, a monoterpenoid phenol compound present in the essential oil fraction of oregano and thyme, and in the essential oil of other numerous aromatic plants. Its low toxicity together with its pleasant taste and smell suggests its use as a food additive to prevent bacterial contamination.The current work is focused on conformational and hydration properties of carvacrol in aqueous solutions, modeled by molecular dynamics simulation (MD), which has prove to be a highly reliable technique to predict properties of biomolecules in solution. The MD simulations (GROMACS package) are performed at constant pressure and temperature at normal conditions (P= 1bar,T= 300K) in nanoseconds time scale in aqueous solutions. Water was modeled using the SPC/E model, while charges were optimized using Gaussian98 programme. DM results show structural and dynamical preferences of carvacrol in water. The dihedral angles trajectories between the ring and the side group reveal a relative flexibility of the molecule. The hydrogen bonds statistic shows the existence of some internal hydrogen bonds that could play a role in stabilizing the molecular structure. This work brings also interesting data regarding the influence of carvacrol on the water structure, disturbing the H bonding pattern of SPC/E water as well as its dynamics.

In this report, bond-based 2D quadratic indices, a novel TOMOCOMD-CARDD molecular descriptor and linear discriminant analysis (LDA) were used to obtain a quantitative linear model -in accordance with the OECD principles for (Q)SAR validation- that discriminates between anthelmintic and non-anthelmintic drug-like organic-compounds. The classification model obtained classified correctly 87,46%, in the training set (352 chemicals). Furthermore, 165 compounds already reported like anthelmintics were screened in a simulated virtual screening experiment (external-test validation). As a result, it correctly classified 135 out of 165 (81.82%) of the chemicals, which were the most important 46 FAPRONATURA 2009 Second International Symposia on Pharmacology of Natural Products Varadero, Cuba.

Another LDA model was carried out to outline some conclusions about the possible modes of action of anthelmintic drugs. It has an accuracy of 83.69 % in the training set, and 87.41% in the external prediction set. After that, the developed model was used in a virtual screening to predict the biological activity of all the chemicals (19) that have been obtained by some of our research groups (Dr. Jose O. Guerra) from Agave brittoniana Trel. spp. Brachypus, where several compounds (12) were identified by models as anthelmintic. Finally, we have selected a group of 5 of them as theoretical most active chemicals to be tested in an ¨in vitro¨ assay and one of them were evaluated ¨in vivo¨. As a result, the experimental observations confirm theoretical predictions to a great extent as well as also show several candidates as fasciolicide drug-like compounds.

The mayor impact in this process is always the identification of novel lead compounds once isolated. Recently, the computational methods have become a suitable alternative to reduce the costly failures of drug candidates in clinical trials by filtering virtual libraries of chemicals. It is known that the enzyme tyrosinase is election pharmacological target in the treatment of skin hyperpigmentation. So the main purpose of this study is developing QSAR (Quantitative Structure-Activity Relationship) models that can classify tyrosinase inhibitors isolated from herbal plants from inactive ones for virtual identification of novel compounds. First a database of 658 organic compounds of great structural variation, 246 of which reported activity anti-tyrosinase is collected. Every active and inactive molecule in the database is parameterized in atom-based linear descriptors by means of the TOMOCOMD-CARDD program. K-means cluster analysis algorithms were used to obtain the training and test series. Linear Discriminant Analysis was used to get classification functions. Twelve QSAR models of tyrosinase inhibitory activity were achieved. Globally good classification of 93.51% was observed for best model in the training set and 91.67% for the external prediction set. Finally, these fitted models were used in the screening of new cycloartane compounds isolated from herbal plants. A good behavior is shown between the theoretical and experimental results. The current report could help to shed some clues in the identification of new tyrosinase inhibitors for entering in the pipeline of drug development. 47 FAPRONATURA 2009 Second International Symposia on Pharmacology of Natural Products Varadero, Cuba.

OC-13 TITYUS SERRULATUS SCORPION VENOM: TOXINS, MECHANISMS OF ACTION AND POSSIBLE MEDICINE APPLICATIONS Souza, C.M.V. Instituto Vital Brazil, Rua Maestro José Botelho No 64, Niterói, Rio de Janeiro, BRASIL. E-mail: [email protected]; [email protected] In Brazil human scorpionism sharply increased in the last ten years. The “yellow scorpion” Tityus serrulatus (TS) is involved in most of severe and lethal cases. The venom of this specie is a complex pool of low molecular basic proteins which acts mainly on ions channels resulting in transient but important disturbs on neuronal electric conduction and massive release of neurotransmitters, inflammatory and immune modulators. Despite of these, studies on TS toxins for medicine uses are not well developed than Cuban or Chinese scorpion species. Recent proteomic approaches showed the presence of hyaluronidase, hypotensines and other active peptides in TS venom. Machrophages immunomodulation and Nitric Oxide stimulation also has been described. Fields for possible uses of this venom and toxins as pharmacological tools are of great interest. In this paper we present a review of recent knowledge on TS venom this major action mechanisms, physiopathology and discuss the possibilities of future research on its medicine application.

SABADO 6 de junio / SATURDAY, June 6 OC-15 THE USE OF NATURAL HEPATOTOXICITY. PRODUCTS IN CHRONIC LIVER DISEASE AND HERBAL Zeki Yesilova Gülhane Military Medical Academy, Division of Gastroenterology and Hepatology, Etlik, TR-06018 and Ankara, Turkey E-mail: [email protected] Chronic injury leading to fibrosis in the liver occurs in response to a variety of insults, including viral hepatitis (especially hepatitis B and C), alcohol abuse, drugs, metabolic diseases due to overload of iron or copper, autoimmune attack on hepatocytes or congenital abnormalities. Recent evidences have shown an increasing demand of natural products, with proven hepatoprotective properties when used in the treatment of chronic liver diseases. In-depth studies have proved Sylibum marianum to be anti-oxidative, anti-lipidperoxidative, antifibrotic, and liver regenerative. Glycyrrhiza glabra has been shown to be hepatoprotective and capable of inducing an indigenous interferon. Picrorhiza kurroa is proved to be anti-inflammatory, hepatoprotective and immunomodulatory. Extensive studies on Phyllanthus amarus have confirmed this plant preparation as being antiviral against hepatitis B and C viruses, hepatoprotective and immunomodulating. It has also been reported that Cuban natural products (Mangifera indica L. (MSBE), Erythroxylum minutifolium, Erythroxylum confusum and Thalassia testudinum) extracts are able to reduce damage of the rat hepatocytes induced by different toxicants. On the other hand, herbal hepatotoxicity has been recognized for many years. Acute and/or chronic liver damage occurred after ingestion of some Chinese herbs, herbals that contain pyrrolizidine alkaloids, germander, greater celandine, kava, atractylis gummifera, callilepsis laureola, senna alkaloids, chaparral and many others. Because histologic studies in cases of herbal hepatotoxicity are relatively few, the nature of liver injury is not always known. In conclusion, licensing regulations and pharmacovigilance regarding herbal products are still incomplete and clearcut proof of their efficacy in liver diseases is sparse. OC-16 NATURAL PRODUCTS AS ALTERNATIVE TREATMENTS FOR METABOLIC BONE DISORDERS Cagatay Oktenli GATA Haydarpasa Training Hostipal, Division of Internal Medicine, Tibbiye Cad., TR-34668 and Istanbul, Turkey E-mail: [email protected] Bone is a multifunctional tissue that consists of a structural framework of mineralized matrix and contains osteocytes, osteoblasts, osteoclasts, chondrocytes, endothelial cells, immune and hemopoietic cells. Bone remodeling, a continual process that remove old calcified matrix and regenerate new one synthesizing cells. The cell responsible for bone resorption is osteoclast and the cell generating new bone is osteoblast. An imbalance in the activity of osteoclasts and osteoblasts leads to adult skeletal defects including osteoporosis, Paget disease, and osteolysis associated with periodontal diseases and multiple myeloma. Recently, the use of herbal, non-mineral and non-vitamin supplements has expanded tremendously. To find natural products having a stimulatory activity on osteoblast differentiation, several hundreds of plant extracts were screened, but only few are subjected to the scientific evaluation and have been studied in animals or humans to prove their potency. 50 FAPRONATURA 2009 Second International Symposia on Pharmacology of Natural Products Varadero, Cuba. June 3-7, 2009 http://www.scf.sld.cu Revista Cubana de Plantas Medicinales vol. 14 (Suplemento Especial):51, 2009 Various traditional herbal formulae in Chinese and Ayurvedic medicine have demonstrable effects in pharmacological models of osteoporosis. Potential usefulness of S. miltiorrhiza and the identified tanshinones has been suggested in treatment of diseases involving bone loss. A methanol extract of the aerial parts of Eclipta prostrata L. (Compositae) was found significantly to increase osteoblast differentiation. Increasing observational epidemiological studies have also examined the linkage between dietary intake of phytoestrogens and bone mass in humans and found soy protein or soy phytoestrogen intake beneficial in maintaining or modestly improving bone mass. In conclusion, although our understanding of nutrients and other components affecting bone health continues to grow, the process of acquiring knowledge is not over.

The atherothrombotic diseases (myocardial infarction, stroke, lower limb thrombosis) are among the first causes of death and disability around the World., therefore there is a need for preventive strategies Antiplatelet drugs are prescribed for this purpose, however, the inter-individual differences with respect to the efficacy of the available drugs makes the search for new therapeutic options a current matter of investigation. Some phenolyc compounds isolated from plants inhibit platelet aggregation Therefore, the aim of the Group for Research on Natural Products and Traditional Medicine of the National Institute of Angiology and Vascular Surgery of Cuba is to characterize the potential antiplatelet agents among polyphenol-rich plants with traditional use. The plant extracts were prepared from Citrus aurantifolia Ch., Morinda citrifolia L and Wendita calysina leaves, Citrus sinensis L fruit peels and Zingiber officimale Rosc. rhizhome in 50 % ethanol. Ethanol was removed by rotoevaporation. Their antiplatelet effects were assessed by the turbidimetric method of platelet aggregation in platelet-rich plasma (PRP). For “In vitro assays 285 µL of human PRP were incubated with 10 µl of an extract by two minutes before the addition of ADP , collagen, epinephrine or arachidonic acid) as platelet agonists. The “ex vivo “effects of plant extracts on platelet aggregation were evaluated by adding ADP to 400 µL of PRP obtained from pretreated rats. The “in vitro” assays demonstrated a concentration –dependent inhibition of platelet aggregation and differences among the extracts with respect to their effects against different platelet agonist used...The “ex vivo” experiments have demonstrated that the “in vitro results are not “experimental artifacts” and suggest that this effect may be clinically relevant. This is a confirmation that this research strategy is useful for discovering of new antithrombotic agents from the Nature. OC-18 DEVELOPING ANTI-INFLAMMATORY PHARMACEUTICAL EXPERIENCE WITH ORGANIC SOURCED PUR 0110. GRADE BOTANICAL DRUGS: Dr André P. Boulet, PhD. President & COO, PurGenesis Technologies Inc., Montmagny, Quebec, Canada. Plants have been used as a source of medicine throughout history and even today serve as the basis for many pharmaceuticals. As the pharmaceutical industry was maturing, it adopted the synthetic approach to drug discovery with the vision that it could fulfill its needs for new drugs. This modem approach did not succeed in providing new drugs to the pharmaceutical industry resulting in a growing market for botanical drugs. Indeed, 51 FAPRONATURA 2009 Second International Symposia on Pharmacology of Natural Products Varadero, Cuba. June 3-7, 2009 http://www.scf.sld.cu Revista Cubana de Plantas Medicinales vol. 14 (Suplemento Especial):52, 2009 Botanical drugs were worth $130,000 in 2008, but this segment is expected to reach more than $2 billion in 2013. The FDA's guidelines, established in 2004, for the approval of prescription botanical drugs focuses on botanical drug safety, efficacy and product consistency. Well designed clinical trials can address the FDA`s safety and efficacy concerns. Product consistency of the complex collection of phytochemicals inherent to botanical extracts remains a major challenge. While FDA`s guidelines remain the backbone of any botanical drug development within the Botanical Drug Industry, regulatory requirements difference between USA, Canada, Europe and the rest of the world are also challenging when developing such new drugs. PurGenesis Technologies Inc. is a Canadian privately owned company that develops and manufactures active complex ingredients from natural sources. The core platform of PurGenesis’ research and development efforts is a uniform and well-characterized molecular complex derived from green plants. This molecular complex, which is characterized by a specific three-dimensional composition of pigments, proteins and lipids, is extracted from certified organic plants. Traceability from the seed to the pills is under extensive QA & QC methods. Characterization utilizing marker compounds, DNA fingerprint and bioresponse profile focusing on the integrated biological response of cells to the entire collections of related compounds having multiple activities interacting for a greater total activity. Studies conducted by PurGenesis indicate that PUR0110 (an extract derived from this complex), prevents the formation and noxious activity of Reactive Oxygen Species (ROS). ROS are a natural by-product of cellular metabolism, but various disease processes as well as exposure to environmental stressor (UV radiation, heat and pollution), can cause a dramatic increase in ROS levels, which can result in significant damage to cell structures. The efficacy of PUR0110 is based on its ability to capture noxious energy from all types of Reactive Oxygen Species (ROS), including singlet oxygen, through its trapping system. While other antioxidants have the capacity to capture noxious energy, their limited ability to dissipate this energy restricts the duration of effect. In contrast, PUR0110 has the capacity to continue to dissipate this energy through its molecular complex providing an unprecedented regenerating or turnover mode of action, which confers long-lasting antioxidant activity. PUR0110 has also been demonstrated to have a strong anti-inflammatory effect. PurGenesis has conducted a number of in vitro and in vivo studies illustrating specific actions of PUR0110 on the inflammatory process which include Balancing inflammatory cytokines and Neutralizing harmful energy produced during inflammation. These studies led to the exploration of PUR0110 in disease states such as psoriasis and ulcerative colitis, where inflammation is thought to play a key role in the disease process. Indeed, the company is initiating its first in human study with PUR 0110 as an enema formulation which will be following by a study in psoriasis patients in the falls 2009. Plants continue to serve as a valuable source of therapeutic compounds because of their vast biosynthetic capacity and PurGenesis is dedicated to the extraction and development of such products. OC-19 A RANDOMIZED CONTROLLED TRIAL OF VIUSID IN COMBINATION TO DIET AND EXERCISE IN PATIENTS WITH NONALCOHOLIC STEATOHEPATITIS. Dr. Eduardo Vilar*, Adelaida Rodríguez**, Bienvenido Gra**, Enrique Arús*, Raimundo Llanio****, Luis Calzadilla*, Ali Yasells****, María del Rosario Abreu*****. *Departamento de Hepatología, **Departamento de Nutrición *** Departamento de Patología, ****Departamento de Gastroenterología, *****Departamento de Bioestadística. Instituto Nacional de Gastroenterología, Habana, Cuba. Nonalcoholic steatohepatitis is a significant health problem for which there is no universally accepted pharmacologic treatment. Nowadays, lifestyle modification remains the gold standard to treat nonalcoholic steatohepatitis. The combination of weight loss and antioxidant drugs to ameliorate insulin resistance and improve steatosis, inflammation, and fibrosis, provide the rational for therapeutic trials. Aim: Our study evaluated the efficacy and safety of viusid in association with diet and exercise for nonalcoholic steatohepatitis. Methods: A randomized, controlled, and parallel-group trial was conduced in a tertiary care academic center 52 FAPRONATURA 2009 Second International Symposia on Pharmacology of Natural Products Varadero, Cuba. June 3-7, 2009 http://www.scf.sld.cu Revista Cubana de Plantas Medicinales vol. 14 (Suplemento Especial):53, 2009 (National Institute of Gastroenterology, Havana, Cuba). We randomly assigned 60 patients with liver biopsyproven steatohepatitis to 6 months of treatment with a hypocaloric diet plus aerobic exercise daily and 3 viusid sachets daily or a hypocaloric diet and exercise. The clinical research network score with minor modifications was used to compare the histologic changes as the primary end point. All biopsies were scored by a single pathologist unaware to the patient clinical and biochemical data, treatment assigned and liver biopsy sequence. Biochemical, metabolic, and anthropometric tests were secondary end points. Results: A significant improvement in steatosis, necroinflammation, and fibrosis was seen in each group of treatment (P<0.01 for each feature). The viusid group, as compared with control group, significantly reduced the mean total score (from 4.78 to 0.89 points in the viusid group versus 4.95 to 2.64 points in the control group [P=0.004]). On between groups comparison, viusid was associated with a significantly greater improvement in steatosis (P<0.001), ballooning (P=0.002), and lobular inflammation (P=0.025), but not fibrosis (P=0.25). Viusid was well tolerated. Conclusions: Our results indicate that treatment with diet and exercise leads to a notable improvement in histological features of nonalcoholic steatohepatitis; however, the administration of viusid intensifies the improvements of histological findings, especially of steatosis and inflammation.

Hernández Yero, David Vargas González, Raquel Jorge González National Institute of Endocrinology, Hospital Pediátrico del Cerro. Introduction: The nutricional supplement Diamel, can have a favourable influence in the diabetes type 2. This supplement contains amino acids, vitamins, oligoelements and extracts of the lettuce and the bilberry, activated by a process of the molecular magnetization, and acts at level of the pancreatic beta cells and the gastrointestinal tractus. Objectives: To evaluate sensitivity to the insulin and the function of the beta cells with the determination of the Homa-B and Homa-IR indexes, in patients with type 2 diabetes that received treatment with glibenclamide more Diamel. Design and methods of the investigation: A total 60 patients with type 2 diabetes was selected at random to administer Diamel plus glibenclamide (group A, n=30) and glibenclamide alone, group control, (group B, n=30). Two capsules of Diamel were administered 30 minutes before the breakfast, lunch and the supper. The patients including were between 40 and 65 years of the age and had 0 to 10 years of history of the diabetes. Those patients with the greater HbA1c from 10% or with moderate or severe chronic complications were excluded. The patients were followed during 6 months with basal determinations of insulinemia and glucemia, as well as glucemia post-prandiales of two hours and HbA1ç and determinations of the Homa-B indixes and Homa-IR to the beginning, to the 3 and 6 months. Results: The patients of the group A and group B presented to similar characteristic clinicals at the beginning and received identical recommendations about nutrition and physical activity. The levels of the glicemic control, measured by fast blood glucose and post-prandial blood glucose and the HbA1c displayed a significant diminution in the group that used the Diamel. The correlation between fast blood glucose and cells beta function expressed at HOMA - B was positive in both groups at the beginning of the study but it was more significant positive mind in the group A To that in group B, to the 6 months of the pursuit. The relation with the HbA1c was a weak positive correlation to the 6 months in group B whereas the group with the Diamel these results were significant. The correlations between the HOMA - IR with the BMI and the abdominal circumference and waist/hip index remained positives in both groups, but was more consistent statistically and significative in group A. Conclusions: The nutricional suplement was useful in to increase the function of the beta cells in patients with type 2 diabetes during the 6 months of the pursuit. The anthropometric variables BMI, waist circumference and index waist / hip presented a correlation significant with the index Homa-IR with the use of the Diamel. 53 FAPRONATURA 2009 Second International Symposia on Pharmacology of Natural Products Varadero, Cuba.

E-mail: [email protected] y [email protected] Since 1985, the Microbiology Department of CEBIMAR have isolated marine microorganisms from sea water, the objective of this, was to create a Marine Bacteria Collection (CBM) with biotechnology potentialities. These microorganisms had been classified on basis of capacity of heterotrophic bacteria to producing different substances from simple media during their metabolism. The CBM contain more than 400 strains with capacity to produce important metabolites like as antitumor activities, antimicrobial activities, surfactants, etc. In this collection more than 120 strains are capable to use hydrocarbons as unique carbon and energy source, with this potentialities were obtained two bioproducts at industrial scale, called IDO-503 and BIOIL-FC. The first one was used in microbial enhance oil recovery in the Boca de Jaruco oil field and was capable to recover more than 10 000 ton of crude oil. BIOIL-FC was developed against oil pollution and was used since 1992 with excellent results at different ecosystems like mangroves, beaches, bays, rivers and soil. The oxidation of all fractions of oil was significative in all of cases more than 85 %. We develop, at pilot scale, some antimicrobial substances used against different pathogenic agents, in order to obtain standardized products that will be used for increasing the quality of live. OC-22 PHARMACOLOGICAL CHARACTERIZATION OF BIOACTIVE COMPOUNDS FROM THE SEA ANEMONE EPICYSTIS CRUCIFER.

Sea anemones represent a valuable source of different biologically active compounds, being the Na+ and K+ channel toxins the most known. In this work we studied chromatographic fractions of high and intermediate purity, obtained from the sea anemone Epicystis crucifer, on voltage- and ligand-activated currents. The biological evaluations were done in dorsal root ganglion (DRGs) cells in culture and in fresh isolated cells of the snail Helix aspersa, using whole cell patch clamp techniques. The evaluation of Sephadex G-50 fractions showed Na+, K+ and acid-sensing ionic channels (ASICs) channel blocking actions in fraction III and antiglutamatergic action in fraction II, respectively. Fraction II and III were submitted to further purification steps comprising ion exchange and reversed-phase chromatography. A peptidic compound (MW 5297.88 Da according to MALDI-TOF measurement) was obtained from Fraction II, which blocked glutamate (1 mM) currents in isolated snails neurons (IC50=7.36 ± 3.9 µM, n=15 ). Also, another new peptidic compound was obtained from fraction III (MW 3475 Da according to MALDI-TOF measurement). In preliminary experiments, it is shown that this peptide inhibited ASICs currents on DRG cells in the micromolar range (n=5). The characterization of these peptides on other currents is now in progress. These findings support the presence of Na+ and K+ channel toxins as well as novel glutamate and ASICs inhibitors in this sea anemone that should be further characterized because of their potential therapeutic interest. 54 FAPRONATURA 2009 Second International Symposia on Pharmacology of Natural Products Varadero, Cuba.

Menéndez R, Garateix A, García T, Morales R, Marrero G, Rodeiro I, Laguna A, Regalado E, Fernández MD. Centro de Bioproductos Marinos. Agencia de Medio Ambiente. La Habana. Cuba. BM-21, the standardized extract obtained from the sea grass T. testudinum, a marine plant highly abundant in Cuban coasts, was evaluated for its antioxidant and citoprotective effects in experimental models. The plant extracts showed free radical scavenger effects on OH*, ABTS+, O*- and peroxilic radicals, as well as inhibitory effects on “in vitro” spontaneous and metal-induced lipid peroxidation in brain and liver membranes, respectively. Also, pretreatment with BM-21 (24h, 5 - 100µg.ml-1) prevented the tert-butyl hydroperoxide-induced cell damage (IC50 190 µg.mL-1) the rise in malondialdehide (MDA) and the significant depletion of reduced glutathione (GSH) of freshly isolated rat hepatocytes. Accordingly, BM-21 exhibited remarkable hepatoprotective activity “in vivo” against acetaminophen-induced hepatotoxicity (1.5 g.kg-1) in mice after single and repeated oral administration (100 mg.kg-1). Besides, repeated oral administration (100 and 400 mg.kg-1) prevented death rate and neurological symptoms after unilateral carotid occlusion in Mongolian gerbils and decreased malondialdehide content in whole brain at the same doses. Oral administration of BM-21 (400 mg.kg-1) prevented toxicity induced by the subcutaneous administration of achrylamide (70 mg.kg-1). At the same doses, the extract restored stress oxidative parameters in sciatic nerve, liver and whole brain homogenates. In conclusion, this study is the first to demonstrated the citoproof T. testudinum extract in experimental models. The key finding of the present study in that BM-21 has central and peripheral neurorpotective effects. Although further investigations ate necessary to identify the effective citoprotective compounds our present results suggest that BM-21 contain selective antioxidants that could be useful in preventing cell damage caused by oxidative stress. OC-24 NEW COMPOUNDS OBTAINED PHARMACOLOGICAL ACTIVITY FROM SPONGES FROM CUBAN COASTS WITH Erik Regalado, Abilio Laguna, Olivie Thomas* Centre of Marine Bioproducts, Loma & 37, Vedado, PC 10600, Havana City, Cuba; e-mail: [email protected] *Laboratory of Chemistry of Bioactive Molecules and Fragrances, University of Nice-Sophia Antipolis, Faculty of Sciences, Nice, France. The exploration of the marine environment as a potential source of bioactive natural products with original structures is in full expansion. Nowadays, there are only four marine-derived products currently available: vidarabine (antiviral), cytarabine (antitumor), cephalosporine (antibiotic) and (Yondelis®, antitumor). Furthermore, more than 15 new compounds isolated from ascidians, seaweeds, bryozoans, or sponges are now under clinical trials for drug development, mainly for anticancer therapy. Prialt™, an omega conotoxin isolated from Conus magus, is the first drug of marine origin to reach the FDA approvable status, and is the most powerful painkiller known to date. In recent years, several compounds has been obtained from sponges from all over the world that shows promissory antitumor activity and our group decided to search for new bioactive substances with pharmacological activity from sponges that grows in Cuban coasts. These studies were aimed at developing a standardized approach to characterize the marine chemo-diversity in a model community. Several sponges were studied and those that it extracts shows antitumor activity were studied in order to isolate its main components. From Agelas sp. were obtained 5 bromopyrrole alkaloids and from Niphates sp. were obtained 6 nucleosides that never have been previously described from a marine organism. 55 FAPRONATURA 2009 Second International Symposia on Pharmacology of Natural Products Varadero, Cuba.

In our continuing investigations to determine if some of the compounds produced by these marine organisms can possess industrial applications, the common reef sponge Amphimedon compressa was collected by SCUBA in Port Royal, Jamaica, lyophilized and extracted with MeOH:CH2Cl2 (1:1) at room temperature. The crude extract, when concentrated under reduced pressure, yielded a red-brown pasty residue which, on chromatography with Sephadex LH-20, afforded the pyridinium alkaloid amphitoxin as its major constituent, the structure of which was elucidated by interpretation of spectroscopic data from 1H and 13C NMR experiments. The crude extract and the fractions containing high percentages of the metabolite were assessed for ichthyotoxic activity over a three hour period using the Xiphophorus variatus (moon fish) in which note was taken of the rate and manner of swimming activity as well as mortality in the organism. Insecticidal activity with the agriculturally significant pest Cylas formicarius elegantulus (Sweet potato weevil) was examined to determine the potential of the extract for an agricultural application. The extracts were dissolved in acetone and topically applied to the dorsal part of the insects. The ability of the extract to cause mortality in the rodent, Rattus norvegicus (Norway rat), was examined with fifteen randomly selected rats who were given varying concentrations of aqueous solutions of the fractions and the crude extract. From the experiments conducted, moderate insecticidal activity was observed while toxicity of the fish was evidenced by the high mortality rates in all the fractions tested. The species of rodent examined did not appear to be adversely affected by the metabolite under study.

It has become obvious that the marine environment produces chemical compounds that have significant activities against mammalian cell. Perhaps the first notable discovery of biologically active compounds from marine source was reported from 1950 to 1956 by Bergman et al on two compounds Spogouridine, spongothymidine. Introduction: There are significant number of compounds available from marine source presently on clinical /preclinical trials as anticancer agents. Although currently there are no approved agent that have come directly from the marine environment. It was realized that marine environment should produce a very large number of exquisitely potent compounds, a probable reason for the presence of extremely active chemo types that the dilution effect of see water means that any toxins must be very potent , as it usually has to cross a finite distance to deter any predator. 56 FAPRONATURA 2009 Second International Symposia on Pharmacology of Natural Products Varadero, Cuba.

OC-27 IMPACT ON CUBA NEONATAL MORTALITY WITH THE USE OF A NATURAL SURFACTANT. FUTURE NEW INDICATIONS Fernández-Limia O, Díaz E. National Centre for Animal and Plant Health (CENSA). Carretera de Jamaica y Autopista Nacional, San José de las Lajas, La Habana, Cuba. E-mail: [email protected] Since the beginning of the 1980s, the application of natural first and synthetic surfactants after, either therapeutic or prophylactic has had a major impact in reducing infant mortality by Newborn Respiratory Distress Syndrome (NRDS) formerly called Hyaline Membrane Syndrome which is observed in premature infants and is caused by lung immaturity with a deficit of endogenous surfactant. Due to difficulties in acquiring these drugs, in part because of its high price and mostly by the blockade that is subject the country and at neonatologist’s request, for over 10 years there has been a natural surfactant Surfacen of porcine origin produced by our center. Production has been increased so that now fully meets the needs of the country. This, together with the artificial ventilatory facilities, has been determined a reduction in infant mortality by SDRN of 0.8 to 0.2 per 1000 live births. Currently under clinical efficacy evaluation in other conditions such as the Acute Respiratory Distress Syndrome (ARDS) that occurs at any age after birth for many reasons that cause lung inflammation and transudate of protein and other elements of the blood which inactivate the surfactant system causing alveolar collapse and reduced gas exchange due to the, anti-inflammatory, antimicrobial and antioxidant properties that Surfacen has. In addition there a number of questions as the effect of long-term complications, the method of administration, combined with new maneuvers, its prophylactic use in SDRN and continue the search for new ventilation surfactants with greater efficacy and lower cost.

Autopista Novia del Mediodía, Km 6 ½, La Lisa, Ciudad de La Habana, Cuba. *[email protected] The antiviral activity of Phyllanthus orbicularis against herpesviruses and hepatotropic viruses has extensively been investigated. In this work, the inhibitory activity of the aqueous extract from this Cuban endemic plant was evaluated against Poliovirus 1, Coxsackievirus B5 and Echovirus 9. Citotoxicity of the test extract was assessed by means of the MTT colorimetric assay and antiviral activity was determined as a function of viral-induced cytopathic effect (CPE) reduction under a light microscope. The time of inhibition was studied using a time-ofaddition experiment and virucidal assays were carried out in order to assess the extracellular virus-inactivating capacity of the plant extract. P. orbicularis inhibited the in vitro propagation of all tested viruses. CE50 values ranged from 115 to 130 µg/mL. Selectivity indexes (SI) recorded for this extract was greater than 9. An extracellular virucidal activity was found for this plant since viral suspensions titres decreased by 1 log10 or more after treatment with the extract. P. orbicularis was effective against all studied enteroviruses. No previously works are available in literature describing anti enteroviral activity from this species.

For that reason, two experimental techniques were developed: edema to plant induced by dextrano and granulomas induced by cotton disks. In the experimental test doses of 2.5, 5.0 and 10 mg/Kg of weight were used , the volume of administration of 10 mL/Kg; as positive control a solution of Indometacine was used (7 and 5 mg/Kg) and negative control water distilled. The gonfrenol-3-O - [ α- L-rhamnosil-(1→2) - β- D-xilósido] presented antiinflammatory activity in the acute phase to superior dose to 2.5 mg/Kg in the experimental pattern of edema to plant induced by dextrano; also, this activity increased when increasing the dose. In the granulomas pattern induced by cotton disks, the compound presented similar anti-inflammatory activity to the Indometacine to all the evaluated doses, being bigger the effect to the 10 mg/Kg dose. The statistical analysis was carried out by the test of Kruskal-Wallis with an interval of trust of 99% and a level of significance of 0.816. The flavonol; showed significant dose-dependent inhibition of both acute and chronic inflammation. The activity was comparable to that of the standard reference drug, indometacine The results of the present investigation indicated that the flavonol isolated of B purpurascens, Cav. shows profound antiinflammatory activity Keywords: Boldoa purpurascens, Nyctaginaceae, flavonol glycosides, gomphrenol glycosides.

Introduction: Rhizophora mangle L. has a potential activity against experimental models of acute and chronic gastric ulcers (Sánchez, 2001; 2004; Beringuer, 2006). We were studied another pharmacological test as part of pharmacological II. The not toxic effect was shown in acute and genotoxicological trials. In the present work we described other pharmacological evaluation and chemistry-pharmacology test in the development from a new drug by the treatment of gastroduodenal ulcers. We were proceeding to formulate tablets since laboratory to industrial scale with dried aqueous extract from barks of this plant. We studied the stability of intermediate product and final formulation. We validate the analytical method by CLAR to determinate a mark in tablets as quality indicator in self. Some tests were made to evaluate the gut absorption of active extract and tablets and we determinate the digestibility of protein in presence of the active extract. It was possible to formulate tablet by directed compression in lab and industrial scales. Intermediate product and tablets were stable by 1 year in environmental condition with good quality parameters (technology, chemistry and biological activity). Dried aqueous extract has high gut absorption and this extract not affect the proteins digestibility. The dissolution of tablets was 30-70 % in different dissolution medium. References: 1.

Delgado R Scientific Director and Clinical Pharmacology Department, National Centre of Clinical Trials, Havana, Cuba. Email: [email protected] Since the origin of the man’s existence, plants and other natural sources have been used with medicinal purposes. In Cuba, during several years, aqueous extract from stem bark of Mangifera indica L. was obtained and used during a lot of time by empiric practitioners as nutritional supplement for the treatment of diverse affections. The extract was studied by Centre of Pharmaceutical Chemistry in order to development and standardize pharmaceuticals production and for these purposes were carried out different projects and investigations with the objective to get a complete phytochemical, analytical, toxicological and pharmacological characterization according to international and Cuban regulatory requirements for using phytomedicine products. Few times, in the investigation of medicinal plants in our country, the preclinical evaluation of a natural product is studied in details. These studies have been published in scientific journals with high impact factor. Approximately 15 years, we have been working with this extract, demonstrating antioxidant, anti-inflammatory, analgesic and immunomodulatory activities. The institution began the development of a strategy of clinical evaluation, in order to demonstrate the therapeutic effectiveness of the extract in diverse pharmaceutical forms through controlled clinical trials in diseases with an important inflammatory or/and oxidative stress component that guarantee the introduction of Vimang® like phytomedicine. Up to now, the clinical trials carried out have not shown conclusive results and this is the main challenge of the natural products: To demonstrate their true clinical effectiveness, in spite of they show excellent preclinical activity. In order to confirm it, in the clinical trials, is necessary to dose adjustments, to identify the best time of administration, chronopharmacological determinations, and other pharmacological strategies with the objective to find the best way for using these products in the clinical practice. After the conclusion of preclinical phase, there are many aspects for clarifying in the near future, until to reach the true clinical effectiveness of the products like a standardized phytomedicine. The biggest challenge, therefore, we have not even reached and this is to introduce this phytomedicine in the clinical practice for specific therapeutic indications.

Cervantes M., Penton Roll G. Center for Genetic Engineering and Biotechnology. Havana, Cuba. E-mail: [email protected] Organ specific or systemic autoimmune (AID) and chronic inflammatory diseases (CID), have been largely associated to the lack or failure of immune system regulatory an tolerance induction mechanisms. Mostly as a result of combined genetic, immune regulatory and environmental factors. The genetic predisposition conferred by the HLA have been described but probably not enough to the self-development of AID which are complex diseases that require the confluence of many genes and other factors. Tolerance to self is achieved through multiple and diverse mechanisms. Heading these processes is suppression of immune responses by regulatory T cells. Regulatory T cells control immune responses to self-antigens thereby preventing autoimmunity, and limit responses to foreign antigens thereby minimizing T cell-mediated immunopathology. Natural products have been, and continue to be, a major source of pharmacologically active substances from which drugs can be developed. Natural products capable of modulating the immune system as well as its mechanisms of cytokine production and activation e.g : c-Phycocyanin, Resveratrol, Royal jelly, Boswellic acid, Gum resin of Boswellia serrata tree, N-acetylcysteine, Fish oil, Curcumin (diferuloylmethane), Bromelain, Vitamin-C and vitamin-E, are known. Treg cell's essential role in the management of immune response to specific auto, allo and tumor antigens has also been detailed. Balance between regulatory and effector arms of the immune system is a necessity for immune homeostasis. The importance of direct manipulation of Treg cells using “disease modifying therapies” from natural origin to attenuate hypersensitivity, cancer, infection, autoimmunity and alloimmunity and their further related benefits will be discussed. OC-34 PKC ACTIVATION BY PHORBOL ESTERS ISOLATED FROM JATROPHA CURCAS Li N, Wilkins R, Rauf A, Sim C, Dimaki C* School of Biology, Newcastle University, KGVI building, Newcastle upon Tyne, NE1 7RU, United Kingdom. *E-mail: [email protected] Phorbol esters are plant diterpenes based on the tetracyclic tigliane and mainly occur in the family Euphorbiaceae. Phorbol esters show toxic effects in animals such as inflammation, cell proliferation and differentiation and promote tumour formation. They are also activators of protein kinase C (PKC), by mimicking the normal activator, diacylglycerol (DAG). The toxicity of the seeds and oil of Jatropha curcas (Euphorbiaceae) a plant promoted for biodiesel and animal feed production is partly attributed to the presence of phorbol esters, unique to this species. The bioactivity therefore of the phorbol esters needs to be understood. We report here the fractionation of individual phorbol esters from the seed, oil and defatted seedcake of J. curcas and determination of their PKC activity. The phorbol esters were extracted from the plant material using methanol and their concentration was determined using RP-HPLC with internal standard the phorbol myristate acetate (PMA), a synthetic analogue with high PKC activity. The mixture of phorbol esters was fractionated by analytical HPLC to high purity as determined by diode array detection. The isolated fractions were assayed for activity using TruLight TM PKC-α assay kit (Merck Chemicals Ltd.) which is based on quenching of fluorescence by the phosphorylated peptide. The activity of the J. curcas phorbol esters was evaluated along with a range of synthetic phorbol esters. Phorbol esters profile differed among jatropha extracts of different origin (seed, oil and seedcake). Fractions of J. curcas extracts at the concentrations run showed considerable activation of PKC in comparison to the control. 61 FAPRONATURA 2009 Second International Symposia on Pharmacology of Natural Products Varadero, Cuba.

Rao, M. Vijayakumar, S.K.Ojha and A.K.S. Rawat Pharmacology Laboratory, National Botanical Research Institute, Lucknow – 226 001, Uttar Pradesh, India. Email: [email protected] Introduction: The oesophageal reflux disease has gained clinical and surgical importance over the past decade and it is a common disease that affects children and adults. Oxygen-derived free radicals and superoxide anions are the main cause of free radical damage in reflux oesophagitis.The preventive effect of bioflavonoids rutin, quercetin, and kaempferol, on experimental reflux oesophagitis in rats was investigated. Materials and Methods: Rats separately received rutin quercetin, and kaempferol (100mg/kg x 3days; p.o x o.d), omeprazole (30 mg/kg; i.p x o.d) and given last dose at 1 h prior to surgery. Oesophagitis was induced by ligating between the fore stomach and glandular portion followed by pylorus ligation. Results: Rutin, quercetin and kaempferol significantly inhibited the oesophagitis index to 1.12 ± 0.15 (P<0.001), 1.42 ± 0.12 (P<0.001) and 2.48 ± 0.12 (P<0.001) respectively, as compare to control group 3.2 ± 0.23. Further, acid and pepsin out put of gastric contents were significantly decreased in treated groups. Rutin significantly inhibited the lipid peroxidation (from 0.68 ± 0.024 to 0.34 ± 0.04 nmoles of malonyldialdehyde (MDA) / mg protein) (P <0.001) and increased in levels of catalase to 28.5 ± 1.6 units of catalase activity/ mg protein and superoxide dismutase (SOD) to 88.4 ± 7.5 units/ mg protein (P <0.001). Quercetin and kaempferol also showed significant inhibition in lipid peroxidation (0.38 ± 0.02, and 0.44 ± 0.02) (P <0.01) and enhanced the activities of catalase (24.3 ± 2.6 and 21.5 ± 3.4) (P <0.01) and SOD (85.3 ± 7.2 and 78.60 ± 6.5) activity. Rutin, quercetin and kaempferol treated group significantly increased the glutathione level to 38.5 ± 2.42 (P <0.01), 35.4 ± 3.28 (P <0.01) and 30.5 ± 3.32 (P <0.05) respectively. Rutin, Quercetin and kaempferol significantly attenuated the elevated level of collagen in oesophageal tissue as of the omeprazole. Conclusion: The results suggest bioflavonoids could attenuate the severity of reflux oesophagitis and prevent the oesophageal mucosal damage. OC-36 INTERFERENCE OF SELECTED FLAVONOIDS WITH THE GROWTH OF FILAMENTOUS FUNGUS R. nigricans Lenasi H1, Kužnik M1, Abram V.2 1 Institute of Biochemistry, Medical Faculty, University of Ljubljana, Vrazov trg 1, SI-1000 Ljubljana, Slovenia, [email protected] 2 Chair of Chemistry, Biotechnical Faculty, University of Ljubljana, Jamnikarjeva 101, SI-1000 Ljubljana, Slovenia, [email protected] A saprophytic fungus Rhizopus nigricans (R. nigricans) is a potential pathogen; it may cause some allergic reactions in immunocompromised persons because it interferes with human respiratory tract. Many of generally known fungicides are noxious to human health, therefore it is desirable to find some natural products with inhibitory action on fungal growth, and possibly positive influence on individual healthiness. Natural plant compounds, such as polyphenolics flavonoids, might meet these requirements. Flavonoids are produced by the host plant during fungal infection and interfere with signaling involved in fungal growth and virulence. R. nigricans can be easily grown in vitro. Our previous studies revealed that some steroids, especially progesterone, were fungitoxic; in addition, progesterone activated in the fungus signaling pathway containing cytosolic progesterone receptors. In the present report we investigated the interaction of R. nigricans with flavonoids in comparison to fungitoxic progesterone. Fungal growth inhibition by selected compounds (100 µM) was examined in agar, results expressed in percent of inhibition of hypheal radial spreading: biocanin a (100% inhibition), progesterone (85%), flavone (82%), α-naphthoflavone (49%), chrysin-dimethylether (48%), 6methoxy-flavone (33%), 6-hydroxyflavone (26%), chrysin (20%), kaempferol-trimethylether (14%), genistein 62 FAPRONATURA 2009 Second International Symposia on Pharmacology of Natural Products Varadero, Cuba. June 3-7, 2009 http://www.scf.sld.cu Revista Cubana de Plantas Medicinales vol. 14 (Suplemento Especial):63, 2009 (4%). These results indicated the important role of the hydrophobicity of compounds in their fungitoxic effect. All the above listed flavonoids were also tested as ligands of progesterone receptors in fungal cytosol. Results were obtained by competitive analyses using (3H)progesterone and different excesses of nonlabeled flavonoids. Competition curves and EC50 values revealed the binding of flavonoids to a putative allosteric binding sites on the receptor. So far, we were not able to elucidate the biological role of flavonoid binding to progesterone receptors in R. nigricans, thus further investigation is needed. In conclusion, some natural flavonoids exert toxic effects on R. nigricans and may be used as antifungal compounds. However, the mode of their action as inhibitors of fungal growth is not known yet.

E-mail [email protected] 2 Centre for Studies in Industrial Biotechnology. Universidad de Oriente, Santiago de Cuba. Tamarindus indica L., or tamarind as is usually known, is a medicinal tree with ethnopharmacological uses in microbial diseases. In the present work, the antimicrobial activity of four primary extracts from Tamarindus indica L. leaves, and other five fractions obtained by successive liquid-liquid separation of the most active primary extract, were evaluated against Staphylococcus aureus, Bacillus subtilis, Enterococcus faecalis, Escherichia coli, Pseudomonas aeruginosa, Salmonellas typhimurium and Candida albicans, employing both disk diffusion and the macrodilution tests. Totals phenols as tannic acid and flavonoids as quercetin were also calculated to all extracts by calibration curve, computing the relationships between these chemicals variables and the antimicrobial activity against each specific bacteria. A disclosure was the not appreciable relationship between these variable, with the exception in Bacillus subtilis in which good correlation with total phenols were recognized. Primary extracts showed acceptable levels of activities against Gram positive bacteria, larger than for Gram negative, and inactivity against Candida albicans. Fluid extract at ethanol 70% exhibit a broad spectrum and the high antimicrobial activity in comparison to the others primary extracts, having too the lofty capacity for phenols and flavonoids extraction with 18.494 y 0.369 mg/mL. Aqueous extracts and in particular the obtained from fresh leaves is the less active. The evaluation of the five fractions obtained from the fluid extract in ethanol 70% show the impossibility to find activity for a single fraction while no one was active in lesser doses than the primary fluid extract.

In the present study, we determined the effects of Vimang's tablets and other formulations in persons with chronic pain. The Complex Regional Pain Syndrome (CRPS) (n=15) and Pain Associate with Zoster patients (n=12) received a daily dose of 1800 mg of extract (three coated Vimang tablets, 300 mg each, before meals, and cream 1,2 % as topical agent for 120 and 90 days respectively ). Compress containing the disolution 2 % was utilized on skin lesions in 6 Herpes Zoster (HZ) patients for 30 days. In knee osteoarthritis (OA) patients (n=10), 3 groups were design, group 1 n=3 received a daily dose of 1800 mg (tablets), group 2 n=3 900 mg (tablets) and group 3 received a combination of tablets 900 mg and cream for 90 days. The change in average daily pain daily score through a Likert scale, the area and rate of dynamic allodynia, rate of thermal allodynia, and burning spontaneous pain frequency were evaluated. The deep somatic allodynia and joint's function in CRPS patients were evaluated too. The WOMAC Index (Western Ontario and McMaster Universities) was utilized in knee OA and evaluated the presence of synovitis and effusion for ultrasonography. From week 2 pain scores and sensory abnormalities showed a significant greater improvement. The joint's function increased in CRPS patients. In acute Herpes Zoster patients, the analgesic effect was observed from week 1 and none developed postherpetic neuralgia (PHN). In patients with persistent pain less than 3 months post HZ and PHN, pain scores and sensory abnormalities showed a significant improvement from week 4. The analgesic effect and improved joint's function were observed from week 2 associated with the decreased of the synovial effusion in knee OA patients. Booth effects, the increase and decrease in synovial thickness (mm) were independent of the analgesia. The inhibition of the proliferation was significant only in the group 2. Our results suggest that Vimang's formulations might be appropriate to prevent and treat chronic pain. 1 This works was development the last year in the Department of Biomedical Research, Center of Pharmaceutical Chemistry, actually, Center of Biomolecular Chemistry. ** Garrido G working in this moment at University of Chile.

Instituto de Faramacia y Alimentos (IFAL), Universidad de La Habana. Laboratorios López (Guatemala-Salvador). It has been shown that a decrease in the concentrations of total cholesterol and LDL-col by diets and drugs reduces the risk of peripheral vascular disease. Policosanol and atorvastatin have shown they are capable of reducing both parameters in type II hypercholesterolemia. Some of the steps in the mechanism of action of these drugs are differents and could show results sums, when we used in combination. They also show a pleiotropic effect given by its general antioxidant action and antioxidant effect on the peroxidation. Objectives: To compare the effect of treatment with the combination with Atorvastatin and Atorvastatin-Policosanol on cholesterol concentrations of atherogenic lipoproteins, and the possible antioxidant action. Patients and Methods: We studied 104 patients of both sexes in a range of ages between 40 and 60 years. It was taken as a criterion for inclusion Col-LDL levels above 3.3 mmol / L. Patients were randomly distributed into two groups (one treated with atorvastatin and the other with Atorvastatin + Policosanol). Measurements were made of serum lipoproteins, and hemodynamic studies and oxidative stress before and after three months of treatment. Results: Was found when comparing the groups among themselves, a decrease (p <0.05) in the values of T Col, Col-LDL, TG, VLDL and RAC. Average values were lower (p <0.05) from Col-LDL in the group treated with the combination of both drugs, as well as variations in the parameters which measure oxidative stress (GSH (p <0.05) increased and MDA decreased). Conclusion: The combination of Policosanol and Atorvastatin in the treatment of hypercholesterolemic patients offers better results than using each separately.

Nacional Institute of Gastroenterology, Havana City, Cuba. Introduction: Recent studies have validated the feasibilities of IFN-based therapies for decompensated cirrhotic patients but have provided no data on benefit of therapy in disease progression and survival rates. Aims: The efficacy and safety of antioxidant therapy in preventing disease progression in patients with chronic hepatitis C with compensated and decompensated cirrhosis is unknown. Methods: One hundred patients with chronic hepatitis C who had clinically suspected or histologically confirmed cirrhosis were randomly assigned in a 1:1 ratio to receive 3 sachets of Viusid or placebo daily for a maximum of 96 weeks. The primary end point was the survival rate and the secondary end points were time to disease progression, defined as clinical hepatic decompensation (ascites, encephalopathy, bleeding gastroesophageal varices and spontaneous bacterial peritonitis) or MELD score impairments of at least 4 points as compared with the pretreatment score, and hepatocellular carcinoma. An independent data and safety monitoring board monitored the progress of the study and performed interim analyses of the data. The study was terminated after a median duration of treatment of 64 weeks (ranges, 24-96) owing to a significant difference between each group of treatment and number of end points reached. Results: Primary end point was reached by 92 percent (46 of 50) of patients receiving Viusid 65 FAPRONATURA 2009 Second International Symposia on Pharmacology of Natural Products Varadero, Cuba.

The secondary end point was reached by 50 percent (25 of 50) of patients receiving placebo in comparison with 25 percent (9 of 50) of those receiving Viusid (hazard ratio for time to disease progression, 3 [95% CI. 1.4-6.6]; P=0.002). Hepatocellular carcinoma occurred in 5 patients assigned to placebo as compared with 1 patient assigned to Viusid (hazard ratio, 3.9 [95% CI. 0.5-33]; P=0.17). Viusid tolerability was excellent and none severe adverse event was reported. Conclusions: Continuous treatment with Viusid delays clinical progression in patients with chronic hepatitis C and cirrhosis by significantly reducing the time to disease progression and increasing the survival rates. OC-42 CLINICAL STUDIES CONSIDERATIONS OF ALL BOTANICAL PRODUCTS. Marrero Miragaya MA National Centre of Clinical Trial, Calle 200 esquina 21, Reparto Atabey, Playa. Telephone: 2718308, 2718935. [email protected] Background Botanical products are finished, labeled products that contain vegetable matter as ingredients. A botanical product may be a food (including a dietary supplement), a drug (including a biological drug), a medical device (e.g., gutta-percha), or a cosmetic under the Act. Methods: In this review, the authors will summarize research on many different clinical studies design in different phases. Results: The initial clinical trial for a botanical product currently marketed under the Dietary Supplement Health and Education Act (DSHEA) will ordinarily be a well-controlled study capable of demonstrating effectiveness. In general, initial clinical investigations of nonmarketed botanical preparations should be similar to those of marketed products. Because of the lack of current marketing experience, however, greater concerns could exist about toxicity. Expanded studies of botanicals have the same purpose as expanded studies of synthetic drugs, including further evaluation of dose-response for favorable and unfavorable effects and evaluation of long-term safety and effectiveness, different populations, different stages/severity of disease, and drug-drug interactions. Conclusion: The results show that the sponsor were to eventually identify the active constituents in the new drug application, the active constituents might not be identified during the investigational new drug applications (IND) stage. OC-43 MAGIC BULLETS AND POISON ARROWS: THE ROLE OF NATURAL MEDICINES IN TREATING NEUROCOGNITIVE DECLINE AND NEURODEGENERATION Scholey, A National Institute of Complementary Medicine (NICM) Collaborative research Centre in Neurocognition and Natural medicines, Brain Sciences Institute, Swinburne University, PO Box 218 Hawthorn, Victoria, 3122 AUSTRALIA. [email protected] Like other degenerative diseases, dementia can be considered to be product of a pathological cascade involving progressively accelerating neurotoxic interactions between oxidative stress, inflammatory responses, neurohormonal pathology and compromised cerebral metabolism. These lead to pathological endpoints which, in the case of Alzheimer disease, include neurofibrillary tangle generation and -amyloid deposition, damage to the cholinergic system. Thus neurodegeneration can best be viewed as a “multiple systems breakdown“. Given the multifaceted nature of AD, it is perhaps unsurprising that monopharmacological treatments have had little impact. It may be that systemic polypharmacology inherent in herbal medicines offers a more promising approach to treating neurocognitive health. Herbal medicines often posses a complement of multiple components with different pharmacological targets and some of these are extremely pertinent to processes underlying neurocognitive decline. This talk will present specific empirical examples which make a case for the development and use of herbal medicines in the treatment of neurodegenerative disease. 66 FAPRONATURA 2009 Second International Symposia on Pharmacology of Natural Products Varadero, Cuba.

Eva Obregón Dominguez Instituto Mexicano de Aromaterapia S.C. Introduction: The Linaloe tree (Bursera linaloe, Burseraceae family) native from Mexico, growing in the area known as Alto Balsas in Guerrero. Since the XVII century this essential oil has been obtained through hydrodistillation. Materials and Methods: This Essential Oil was obtained from the fruits of the tree, keeping in mind not to damage the species (ecologically), which was already deteriorated due to the over-exploitation. The sample comes from the 2007 August and September harvest obtained from steam distillation. The chemical analysis was obtained testing the CG gases chromatography with hexano. Results: The Essential Oil has the therpens chemical characterization. The main components are Beta Mirceno, Limoneno, Geraniol, Linalilo and acetate of linalilo. These 5 main components give the aromatic and therapeutic characters to the oil. Bibliography: Hersch, P. and Glass, R. Linaloe: an aromatic challenge.

OC-45 APHRODISIAC ACTIVITY OF CURCULIGO ORCHIODES GAERTN Nagendra Singh Chauhan and V.K.Dixit Department of Pharmaceutical Sciences, Dr. H.S. Gour University, Sagar (M.P.), 470003 India. E-mail: [email protected] Curculigo orchiodes Gaertn, commonly referred to as ‘Kali Musli’, is widely recognized in Ayurvedic system of Indian medicine as tonic and rejuvenator. The rhizomes are also considered aphrodisiac and sexual stimulant. Ethyl acetate fraction of ethanolic extract of the rhizomes was studied for its effect on sexual behavior, spermatogenesis, sperm count and hormone level. Fructose levels in seminal vesicles of albino rats were also recorded. Two doses i.e. 5 and 10 mg/kg of ethyl acetate fraction of ethanol extract on administration in albino rats showed pronounced anabolic and spermatogenic effect in animals of respective groups. The sperm count and fructose levels in seminal vesicle were markedly increased. Improvement in sexual behavior of male rats was characterized by increased mount and intromission frequency and reduced mount and intromission latency. The extract had a dose dependent influence on sperm count and seminal fructose concentration which increased significantly. The extract also increases testosterone level. These may be due to flavanoides present in the extracts. These findings support the folk use of this plant as aphrodisiac. Acknowledgements: Author N. S.

The use of traditional medicines in the management of HIV and AIDS is steadily increasing. There are several reasons for this, including the fact that, there is no cure for HIV and AIDS, and there are no simple and satisfactory programmes for managing this pandemic. On the other hand, because most traditional medicines have been used for decades, they are often assumed to be safe and efficacious. Their concomitant use with prescription drugs has not been well-studied, and in addition their efficacy has not been evaluated in controlled clinical trials. Methods: Peer-reviewed and ethical methodologies have been developed to test the possible toxicity of traditional medicines. The methodology, developed is a sub-chronic repeat dose toxicology study using vervet monkeys (Cercopithecus aethiops), will be presented in respect of PHELA. The safety evaluation of PHELA, using a parallel group, dose escalation and placebo controlled Phase I clinical trials will be presented. In vitro and in vivo studies using cytochrome P-450 metabolizing enzymes have been developed to evaluate which enzymes are involved in metabolizing traditional medicinal products. Results: The toxicological effects of traditional medicines tested using sub-chronic non-human primate models have been conducted and will be reported on. Most of the products have shown no toxicity at dose higher than would be consumed by humans and also that some products have exhibited toxicological effects which are mild and reversible on withdrawal of the product. The Phase I controlled clinical trial has shown that the toxicity exhibited in the vervet monkeys was not reproduced in healthy human participants. The prescribed doses in the latter, however, were not at the same levels. The herbal extract had no effect on the activity of CYP2D6, CYP3A4, CYP1A2, CYP2B6 and CYP2C9. Conclusion: The results show that reliable controlled methodologies have been developed to evaluate the preclinical toxicology, using non-human primate model, and the safety of traditional medicines. The study has also shown how an in vitro system can be used to evaluate the effect of traditional medicines on P450 cytochrome enzymes and how traditional medicines are metabolised. Although in a Phase I study of PHELA, no harmful side effects could be found, a preclinical study with vervets demonstrated toxicity. However, this was due to the very high doses used in vervets. The results will further enable us to develop larger controlled clinical methodologies to evaluate the efficacy of traditional medicines in multi centre studies. OC-47 THE ROLE OF SCIENTIFIC EVIDENCE ON THE ATITUDES OF HERBAL MEDICINE CONSUMERS OF DIADEMA (SÃO PAULO, SOUTHEASTERN BRAZIL) Lanini J, Duarte-Almeida JM, Nappo S, Carlini EA Departamento de Psicobiologia/ UNIFESP Rua Botucatu 862, 04023-062, São Paulo/SP, Brazil. [email protected] Medicinal plants (MP) have been used world-wide for treatment or prevention of health conditions, and due to their natural origin, they have been considered harmless and are commonly used for self-medication. The aim of the study was to evaluate the role of scientific evidence in the decision of making use of MP. Qualitative study carried out with an intentional sample of users of MP. The participants were recruited by means of the chain sampling method and they were inquired to answer a semi-structured interview, that was designed to provide more reliable and complete information about the safety of MP as well as socio-demographic characteristics of the sample. We also asked about the influence of scientific evidence versus TV information on the believes and atitudes in MP of the volunteers. The participants included 13 women and 5 men (average age = 54,4).

The majority (n=11) of them reported that they would continue their treatment besides a negative scientific report. Moreover, 16 volunteers declared that information from TV programs were more significant for their decision than scientific reports. Users tend to rely on personal types of evidence to make decisions regarding MP use. The same observations have also been reported by other authors (Vanderheyden et al., 2004). Our study strengthens the call for more research and educational efforts into this complex area.

PPP-01 CYTOTOXIC ACTIVITIES OF PEROXIDASES AND POLYPHENOLS AND OTHER NATURAL COMPOUNDS HYPOHALOUS ACIDS. PROTECTION BY Ronca F.°*, Tagliazucchi D.^, Maltinti S.°, Gondres Amaro Y., Ronca G.° °Department of Human and Environmental Science, via Roma 55, 56121 Pisa Italy ^ Department of Agricultural Science, via Amendola 2, 42100 Reggio Emilia, Italy *[email protected] Mammalian peroxidases (XPO) have a role in both disease prevention and some pathologies. The oxidants (hipohalous acids, halamines, reactive oxygen species…) generated by myeloperoxidase and eosinophil peroxidase defend the organism from bacteria, parasites and other invading pathogens. Peroxidases closely related to or identical to lactoperoxidase have a role in oral hygen and airway defence. The initiation and accumulation of oxidative damages mediated by XPO play a role in progression of atherosclerosis and cardiovascular diseases, cystic fibrosis, Alzheimer disease. The protective effects of natural compounds such as polyphenols present in foods and beverages against oxygen reactive species (ROS) has been extensively investigated. Few data are available on their effects toward the cytotoxic activity of peroxidases and hypohalous acids. The cytolytic activity of XPO-H2O2-halide ion system and hypohalous acids on human erythrocytes has been used to evaluate the protective effects of wines, vinegars, teas, polyphenols and hydrophilic extracts of some vegetable and fruits. After a lag of several minutes in the presence of XPO-H2O2-halide ion or hypohalous acids erythrocyte lysis is observed. Wines, vinagres and teas increase the lag period and the time of 50% lysis. The protective effect depends from the total polyphenols content, type of polyphenols and it is concentration dependent. The protective effect is not simply related to their capacity to scavenge ROS. Hydrophilic extracts of artichoke, white cabbage, melon and apricot are very effective in protection of erythrocytes from lysis. The protection efficacy is not related to ascorbic acid content. The results obtained show that polyphenols and other natural compounds present in foods and beverages protect not only from ROS damages but also from toxic effects of XPO due to the formation of hypohalous acids. 69 FAPRONATURA 2009 Second International Symposia on Pharmacology of Natural Products Varadero, Cuba.

Traditional balsamic vinegar (TBV) is produced by the alcoholic fermentation and acetic biossidation of cooked and concentrated grape must and subjected to at least 12 year of ageing with sequential transfer in 5 wooden casks of different volume. The final product is drawn from the smallest cask. TBV is a dark, thick and aromatic product containing high sugar concentration, organic acids, polyphenols and melanoidins. The aim of this work is to verify the formation of melanoidins and their contribution to the total antioxidant activity of TBV during ageing process. Samples came from two sets of barrels (A and B) composed of 5 wooden casks at different ageing. HMWM (> 10KDa) were separated from low molecular weight compounds. The TBV and HMWM samples were analyzed for their reducing ability (ferric reducing/antioxidant power FRAP assay ) and radical scavenging activity (ABTS assay). The amount of HMWM was determined by measuring the browning index at 420 nm and by weighing after drying of the samples. During TBV ageing there is an increase of the antioxidant activity and a gradual synthesis and accumulation of HMWM. The increase in antioxidant activity is highly correlated to the increase in the amount of melanoidins measured in the fractions (r= 0.954; P= 0.012 and r= 0.923; P= 0.026 for the set of barrels A in the ABTS and FRAP assays, respectively, and r= 0.991; P= 0.001 and r= 0.990; P= 0.001 for the set of barrels B in the ABTS and FRAP assays, respectively). We found that HMWM may contribute up to 50 % of the total antioxidant activity of aged TBV and can play an important role in protecting the gastrointestinal tract from oxidative damage.

E-mail: [email protected] Introduction: - Numerous studies have shown that moderate red wine consumption can evoke beneficial effects to human health as cardioprotection and/or neuroprotection. This effect has been attributed, in part, to the phenolic compounds present in wines, which shown qualitative and quantitative differences, depending on factors such as grape variety and winemaking technique. The aim of this work was to study the vascular smooth muscle relaxation and the neuroprotective effects of Spanish red wines and to relate them to their polyphenolic composition. Materials and Methods.-Monovarietal red wines were obtained from Vitis vinifera L. grapes: Merlot, Tempranillo, Garnacha and Cabernet-Sauvignon, cultivated at one and same agricultural and climatic conditions, at similar conditions of winemaking. For Neuroprotection study, survival rate of human astrocytoma U-373 MG cell culture was assessed against three toxins, FeSO4, H2O2 and FeSO4 + 1 H2O2 with respect to the studied wines. In the quantitative assessment of cellular viability and proliferation, MTT reduction assay was used.

Vascular reactivity experiments were carried out on thoracic rats aorta rings (Sprage-Dawley). Vasodilatory effects of different doses of wines were studied on arteries pre-contracted with norepinephrine 10-6 M. Isometric contractions were recorded by a Grass model FTO3D force-displacement transducer/79E polygraph. Phenolic compounds were identified and quantified by HPLC-DAD-MS. Results and Conclusions.-The polyphenolics identified in wines were hydroxybenzoics, hydroxycinnamics, flavanols, flavonols, anthocyanins and stilbenes Every wine showed dose-dependent vasodilatory response and neuroprotective effect. Wine from Merlot variety induced the maximum effect for both assays, this wine showing the major content of proanthocyanidins, flavonols and resveratrol.

E-mail: [email protected] INTRODUCCION: Ipomoea stans es una planta que se emplea en la medicina tradicional mexicana para tratar enfermedades renales y biliares, entre otros usos. De esta planta se aisló un glicolípido tetrasacárido, denominado Stancina IV, para el que se mostró un efecto citotóxico sobre las líneas KB, HCT-15, UISIO-SQC1 y OVCAR-5. En este trabajo nosotros proponemos continuar el estudio de este potencial, analizando nuevas líneas celulares, particularmente de origen linfoide, y ampliando los estudios para determinar las concentraciones letales medias (CL50). MATERIALES Y METODOS: Se utilizaron las líneas celulares THP-1, Jurkat y MDCK de la compañía ATCC. El efecto citotóxico del compuesto se determinó a las 24, 48 y 72Hrs de incubación mediante la técnica de MTT. Los resultados se analizaron en un lector de placas marca Labsystem a 570nm. La CL50 se determinó mediante el ajuste de la curva concentración vs viabilidad. RESULTADOS: Nuestros resultados muestran que el compuesto indujo la muerte de las tres líneas celulares analizadas, teniendo un efecto máximo a las 48 horas. Las CL50 fueron para MDCK de 12.3µg/ml, para THP-1 <4µg/ml y para Jurkat de 5.9µg/ml. CONCLUSIONES: El glicolípido tetrasacárido Stancina IV de Ipomoaea stans es capaz de inducir la muerte de un amplio espectro de células de diferente origen, a concentraciones letales medias de 12 a >4 g/ml, por lo que de acuerdo a las guías del NCI ouede ser una molécula adecuada para estudiar como anticancerígeno.

PPP-06 ANTIAGING ACTION OF MELATONIN Prieto-Gómez B., Santibáñez-Olvera C., Moreno-López Y. L., Reyes-Prieto N. M. y Velázquez-Paniagua M. Laboratorio de Neurofisiología Integrativa Depto. de Fisiología, Facultad de Medicina, D.F.04510 ([email protected]) UNAM, México Melatonin is considered the best endogenous antioxidant due to its capacity of crossing every cellular membrane. Over the years, the concentration of melatonin is reduced in the organism and its antioxidant action also falls. Diverse neurodegenerative diseases are associated with this decrease of melatonin and the increase of free radicals. In a previous work, we showed that the chronic application of melatonin reduces the free radicals in the CA1 and CA3 areas of the rat’s hippocampus. Furthermore, an increase of the expression of MAP2 was described. Having demonstrated that there is a better cellular stability in the hippocampus with melatonin, we hypothesized that these cells should also maintain their function. Two groups of Wistar rats were employed for these analyses. Group 1 was treated with melatonin (M) and group two was the control (C) In animals treated for 2, 4 and 8 months with melatonin, the unitary extracellular activity from CA1 hippocampal area was recorded. The spontaneous activity in both M and C groups at 2 months of treatment showed regular firing in the form of bursts, being greater the frequency in the rats dealt with melatonin. In the four months treated rats, the frequency of neuronal firing was reduced in both groups compared with the youngest rats, but the difference between C and M was conserved. After 8 months, the activity of melatonin rats was very similar to the activity of the 2 months old control rats. The results indicate that, even though the animals are not “old”, both groups show changes in the cell firing rate as time goes by and treating them with melatonin “preserves” a greater frequency of firing. PPP-07 MELATONIN REGULATES FERTILITY AND SEXUAL BEHAVIOR OF MALE RATS 1 Velázquez-Paniagua M., 2Parra-Gámez L., 1Gutiérrez-Ruiz J., 2García-Hidalgo A., 1Balderas-López Eduardo J., and 1Prieto-Gómez B. 1 Laboratorio de Neurofisiología Integrativa Departamento de Fisiología, 2Laboratorio de Neuroanatomía Funcional Departamento de Anatomía, Facultad de Medicina UNAM, México D.F. 04510 ([email protected]) A decrease of testosterone in rodents and humans treated with melatonin was demonstrated. In previous experiments, we showed that melatonin reduces the production of spermatozoa and modifies the citoarchitecture of the seminiferous tubules. In this work, we determined the effects of the chronic application of melatonin on fertility and sexual behavior of male Wistar rats and the reversion of these effects. Two months old rats were utilized. They were divided in 2 groups: melatonin (M) with an i.p. daily injection of 1mg/kg of body weight for 3 months; and control (C), with vehicle application. Phase 1, when the pharmacological treatment on 72 FAPRONATURA 2009 Second International Symposia on Pharmacology of Natural Products Varadero, Cuba. June 3-7, 2009 http://www.scf.sld.cu Revista Cubana de Plantas Medicinales vol. 14 (Suplemento Especial):73, 2009 both groups was concluded, we tested fertility and sexual behavior and analyzed the number of spermatozoa. For the fertility analysis, the rats were left to mate and the number of pregnant females was evaluated. For the sexual behavior test, the male rats were left to mate with ovariectomized and hormonally stimulated females. We determined the number of copulatory rats, the accumulated number of copulatory series, the latency in ejaculation and we also counted the spermatozoa. Phase 2, we kept both groups (this time without treatment) for another two months and evaluated them with the previously described analysis. In the first phase, the M group had a significant decrease in the number of spermatozoa and in fertility, and an increased sexual behavior compared to the C group. On the contrary, in the second phase, both the number of spermatozoa and fertility increased and the sexual behavior was reduced. PPP-08 METABOLIC STUDIES ON THE ANTISPERMATOGENIC EFFECT OF CARICA PAPAYA LINN. SEED EXTRACTION Dr C. CHANGAMMA Assistant Professor, Department of Zoology, S.V.University PG centre KAVALI – 524 201 (A.P.) INDIA. E mail: [email protected] In recent years more emphasis is being laid on male rather than female antifertility agents. A number of synthetic compounds have been reported to arrest spermatogenesis or induced functional sterility, but were unsuitable for human use due to toxic manifestations (Waites 1993). Now a days more emphasis is being laid on plant materials which are ecofriendly in approach and interfere with the natural patterns of reproduction (Dixit1992). It was therefore of interest to investigate the effect of biologically active botanical ecofriendly plants such as carica papaya seed extract (Udoh & Kehinde 1999). In the present study healthy adult male Wistar strain albino rats of 90 days age group weighing 120±10g have been selected for experimentation. The experimental rats were administered with 5mg/kg body wt. /day of alcoholic extraction of papaya seed for 7days intramuscularly. The extract was prepared according to WHO protocol CG-04 for the preparation of an alcoholic extract (WHO 1983). After 24hrs from the last dosing the animals were autopsized and the testes were isolated, chilled immediately and used for biochemical analysis. The glycogen metabolism of the testis was evaluated. The decreased glucose and glycogen content was noted through accelerated glycogenolysis. This might reveal its possible mobilization towards either hexose monophosphate or diphosphate pathway. The concentration of the enzymes aldolase and Phosphorylases were elevated slightly. The elevated FDP-aldolase suggest the stepped-up operation of hexose diphosphate pathway. The higher content of pyruvic acid showed higher rate of glycolysis. The decreased content of lactic acid in spite of elevated glycolysis suggests the possible stepped up mobilization of lactic acid into citric acid cycle. Since carbohydrate reserves were decreased in the treated testes and the more mature germinal cell population depends on testicular carbohydrate reserves, impaired germ cell structure and function can be suggested. The degenerative change of germ cells like spermatocytes, spermatids and spermatozoa (Lohia et al 1999&Lohiya et al 2005) supports such a possibility. The decrease in ATPase activity could be attributed to androgen dependent parameters (Mohammad Hossein Dehghan et al 2005). The depleted energy reserves may be responsible for the impaired spermatogenesis in papaya seed extraction treated rat testes. 73 FAPRONATURA 2009 Second International Symposia on Pharmacology of Natural Products Varadero, Cuba.

Medical College of Villa Clara. Clinical Trials Center. Acueduct Rd. and Circunvalation. Santa Clara, Villa Clara, Cuba. E-mail: [email protected] Introduction: Bidens pilosa L, known as romerillo blanco, is widely used by the cuban population. It is chemically composed by flavonoids (quercetin) with proved antioxidant proprieties. Objective: A preclinical study was carried out to evaluate the hepatoprotective effect of Bidens pilosa L in the toxicity induced by paracetamol. Materials and Methods: Male adults MNRI mice were used to evaluate the effect of oral administration of threelevel dose (150, 300 y 600 mg/Kg weight) of Bidens pilosa L extract, 30 minutes before and 2 hours after the hepatotoxicity induced by paracetamol (600 mg/Kg, oral, unique dose) establishing as markers the evaluation of: clinical signals, enzymatic activity of alkaline fosfatase, alanine aminotransferase (ALT) and aspartate aminotransferase (AST); and histological changes produced by hepatocites. Results: Abnormalities in the behavior of animal, were not evidenced during the trials. The analysis of plasmatic concentrations of the tree enzymes in the groups treated with the plant showed high significant statistic in respect to control group treated with paracetamol. Values within the reference values range for the specimen were obtained. Anatomopathological results confirm the cellular protection, either macroscopic or microscopically, in the livers of the animals treated with the plant. Conclusion: To sum up, the administration of Bidens pilosa L extract showed a protective effect on the liver against the toxicity of paracetamol, with no relation between dose and pharmacologic action. PPP-10 PRECLINICAL EVALUATION OF THE ANTI-INFLAMMATORY ACTIVITY OF WHITE BIDENS (ROMERILLO). Pajarín F L, Álvarez G RM. Instituto Superior de Ciencias Médicas Santiago de Cuba. Facultad Medicina I E mail: [email protected] Introduction: The use of the medicinal plants goes back to the oldest origins of the humanity. The past century arose an alive interest by the study and consumption from the medicinal plants which opened a wide field to them to application. Well-known white Bidens in our country like “romerillo” has been used in the treatment of diverse anti-inflammatory affections,and it has inquired into its properties that motivated the development of this investigation. Materials and Methods: An experimental study with the objective was made to determine the effect anti-inflammatory. In these experiment were used: 30 Sprague Dawley male rats, 30 Wistar male rats and 30 Swiss mice. The determination of the anti-inflammatory activity using different pharmacological procedures were used: the technique of granulomas induced by cotton discs, edema to plant by auricular carragenin and edema induced by oil of croton according standardized protocols. The extract was used by oral way in three different doses and its effect was compared with alcohol 50 % (vehicle of the extract), indometacin and bicarbonate to 4 %. Results: The extract was administered to white Bidens in dose of 200mg/kg showing antiinflammatory action comparable with the obtained one with indometacin, using the technique of granulomas induced by cotton discs. This extract is as effective as indometacin in the protection of plant edema induced by carragenin. The extract (200 mg/kg) also inhibits the inflammatory response caused by the croton oil administration. Conclusions: Preclinical evaluation of white bidens (Romerillo) showed anti-inflammatory activity using different models of inflammation. The anti-inflammatory activity of the extract result similar to antiinflammatory drugs indometacin. These results permit to consider the employment of extracts of this plant as phytopharmaceuticals products with anti-inflammatory activity, which could substitute anti-inflammatory drugs as indometacin (or others AINEs), characterized these for their high gastrointestinal toxicity.

Casado C., Gutierrez Y., Garcia G., López R., Miranda M. Pharmacy and Foods Institute. University of Havana. 23 Ave. # 21425 b/ 214 and 222. La Coronela. La Lisa. Havana. Cuba. E-mail: [email protected] Safety on the external use of Murraya paniculata or pain and inflammation relief in arthritis, arthrosis and other rheumatic diseases has been settled by means of a study of Dermal Acute Toxicity, using the methodology described in EODC # 402 Guides. This medicinal plant shows a wide spectrum of biological activities due to an important number of biologically active components reported around the world. In this sense, the anti-inflammatory effect of Murraya paniculata was evaluated, using the Induced Edema Rehearsal, on 15 albino mice (OF1 - males) in 3 work groups: Negative Control, Positive Control (Bencidamina) and Treated Group (Murraya paniculata). The antioxidant and analgesic potential were also determined by means of FRAP (Ferric Reduction Antioxidant Power) and Hot Plate methodologies, respectively. Additionally, a non probabilistic sample (60 patients) was interviewed, in order to evaluate the acceptance of the phytopharmaceutical product produced from Murraya paniculata and the level of trust toward its attributed therapeutic activity, as well as the security of its use. The inflammation percentage produced in the ear was lower, compared to the value reported for the inflammation produced with Croton Oil. The inflammation inhibition was similar for Bencidamina and Murraya paniculata. There were found: a reduction power above 200µΜ, around a 90% of effectiveness of the treatment with the phytopharmaceutical product, and no evidence of adverse reactions in patients. The obtained results let us conclude that this phytopharmaceutical posses high potential for extensive use in traditional medicine, and also for more phytochemical studies. PPP-12 ANTI-INFLAMMATORY ACTIVITY OF TWO FLAVONOLIC EXTRACTS OF THE PETIVERIA ALLIACEA L. IN RATS. Gross Fernández MC. Medical University of Santiago de Cuba. E-mail: mferná[email protected] Introduction:The vegetable specie Petiveria alliacea L. (anamú), is one of the medicinal plants approved by the Ministry of Public Health of Cuba for its integral study; it has been used for various generations for different therapeutic uses; among these are the anti-inflammatory action. Materials and Methods: The Critical Route of Investigation in Medicinal Plants with the elaboration of a herbalist medication for the treatment of Psoriasis; however, the active substances for the anti-inflammatory activity are unknown; therefore assuming that flavonoids are responsible for this action, without having carried out any scientific validation. Due to this, this study is a pharmacological preclinical evaluation I of two flavonolic extracts of this plant to prove antiinflammatory action. These two soft extracts: one of the leaf and another of the root, elaborated according to the procedure described in the Ramal Norm of Public Health 311 and using as menses, hydroalcoholic solutions at 30 and 50%, respectively; according to farmacognostic studies carried out. These extracts underwent liquid – liquid fractioning, using solvents in ascending order of polarity: n-hexane, chloroform, ethyl acetate and nbutanol in a consecutive form, for the obtention of a flavonolic extract of the leaf and another of the root; both from the n-butanol fraction and with a concentration of 10 mg/mL. With these two samples, the preclinic evaluation was carried out using an internationally accepted biological valuation model for the search of new non- steroidal anti-inflammatory drugs: "Subplantar Edema for Carragenin" in rats Sprague Dowley of the masculine sex. The doses tested were: 100, 150 and 180 mg/kg of corporal weight for both extracts, taking into account bibliographical records; a suspension of indomethacine 10 mg/Kg of weight as the positive control and hydroalcoholic mixtures at 30 and 50% as negative controls. The administration route was intraperitoneal. Results: The results demonstrated that both extracts at the three tested doses possess activity and antiinflammatory efficacy; therefore confirming that the flavonoids present in the soft extract of the leaf and the root 75 FAPRONATURA 2009 Second International Symposia on Pharmacology of Natural Products Varadero, Cuba.

Carretera Central Oeste s/n. One of the fields that awake bigger interest in the evaluation pharmacognostic is the study of vegetable species with anti-inflammatory properties. The flavonoids presence confers to some plants anti-inflammatory and antioxidant activity, among others. Presently work intended to evaluate “in vivo” the extracted flavonoid of the Thymus vulgaris (thyme), starting from experimental models of inflammation, as well as to prove its cytotoxic activity. The anti-inflammatory study was carried out by means of the inflammation method in mouse-ear, caused by the administration of 13-acetate of 12-or-tetradecanonoiforbol (TPA) that acts as irritating agent to a dose of 2 µg/ear. The mouse separated in group control, group study treaties with the flavonoid and a group of reference treaty with dexametasone. The typical deviation is determined and the error type gives each one of the obtained stockings, as well as the statistical significance of the differences using the test of Dunnett (P <0,05). For the rehearsal of the cytotoxicity the method was used in vitro of the tetrazolio 3-(4,5-dimetiltiazol-2il)-2,5-difenil-bromide (MTT) that is based in the conversion of the MTT from yellow colour to its formazan of dark blue colour. The viability of the cells is calculated by means of the expression: % viability = Ām/Āc x 100. He was proven that the rehearsed compound reduces the inflammation induced by the TPA in 61%. According to the results obtained in the cytotoxicity rehearsal, the compound doesn't present this activity in front of peritoneal neutrophils to the concentration of 10 µM. Therefore, it could demonstrate himself the anti-inflammatory effectiveness of the flavonoid and their null cytotoxic activity. PPP-14 EVALUATION IN VIVO OF A FLAVONOID OF PIPER AURITUM IN A MODEL OF RETARDED HYPERSENSITIVITY Pérez PL, Ferrándiz D, Iglesias E, Valls AR. Universidad de Camagüey. Circunvalación Norte Km 51/2 Email: [email protected] Plant world brings at principles, with act through out different mechanisms or to different levels of the inflammatory process, with the resulting additive or stimulating effect of their therapeutic propieties and scarce tonicity. Flavonoids are phenolic compounds derived from 2-fenilcroman, that has been reconized since a long time for having anti-inflammatory activity. Therefore, we focused on the evaluation of reactions with retarded hypersensitiveness on an experimental model of the flavonoid taken from the Piper auritum. Swiss, female, albino rats of 3 months old and about 25-30g weight werw used. The retarded hypersensitiveness reaction is induced by external use, with a dosage of 2,4 dinitro-1-flourobencen. Two different procedures are followed. One pre-treatment, were the products are given before the inflammatory reaction triggering, and another posttreatment, where the products are given after the reaction triggering. For the first procedure, the products are applied at a term of 24, 48 and 72 hours, while for the second the same application is done within a period of 2, 24, 48 and 72 hrs. In both test ears thickness is measured with a micrometer at 24 and 72 hrs after the inflammatory process. Hypersensitiveness reaction demostred a reduced inhibition percentage in 24 hrs for the studied product and the regarded drug (dexametasona). It was proved that in 72 hrs the flavonoid had a 73 percent inhibition for the reaction which is considered efficient while comparing it to 83 percent obtained with the dexamentasona. 76 FAPRONATURA 2009 Second International Symposia on Pharmacology of Natural Products Varadero, Cuba.

(MIE) on colitis in 4 % dextran sulfate sodium-induced rats which were supplemented orally for 7 days. MIE (150 mg/Kg) was administrated in two different treatment ways: one group was co-treated with MIE, rectal via during 7 days at the same time of DSS administration (group B), the other group was co-treated with MIE, rectal via like group B, but moreover received MIE (150 mg/Kg) orally during 14 days once a day prior DSS exposition (group C). General observations of clinical signs were performed. Anti-inflammatory activity of MIE was assessed by neutrophil infiltration and colonic lipid peroxidation, and determined by myeloperoxidase (MPO) activity and levels of thiobarbituric acid reactive substances (TBARs), respectively in DSS system. Reduced glutathione (GSH) levels, expression of inflammation related mediators (iNOS, COX-2, TNF-α and TNF receptors 1 and 2), IL-6 and TNFα serum levels were also measured. The results of experiment demonstrated that MIE have anti-inflammatory properties by improvement of clinical signs and inhibition of MPO activity. In addition, administration of MIE 14 days previously to DSS exposition resulted in a decrease of GSH and TBARs levels, reduction of iNOS, COX-2, TNF-α and TNF R-2 expression and depletion of IL-6 and TNF-α serum levels. In conclusion, MIE have antiinflammatory activity and the prior administration become it in a more effective agent. Therefore, we suggest this product for the prevention and treatment of ulcerative colitis. PPP-16 EFFECT OF POLICOSANOL FROM SUGAR CANE ON INFLAMMATORY AND WOUND HEALING IN EXPERIMENTAL MODELS.

Those policosanols are attributed anti-inflammatory and wound healing properties which are not experimentally evaluated yet, so the objective of our work is to evaluate those properties in biological models. Material and Methods: wound healing effect was evaluated using Balb/C mice administered with two preparations one of policosanol 1% in hydrophylic cream and another one of policosanol 0,5% and 1% in sunflower oil. The mice were made a 2 cm diameter wound in the escapular region. Anti-infammatory effects were evaluated in SD rats who were made plantar oedema by using carragenin (acute inflammation) and subcutaneous granuloma (chronic inflammation) by cotton discs and administered with policosanol in sunflower oil at doses of 200, 400 and 800 mg/kg BW. The effect on ear oedema was done in Balb/C mice using PMA as inflammatory agent. Results: there is only significative antiinflammatory effect in the model of plantar oedema at the dose of 800 mg/kg BW and this preparation has no effect on chronic inflammation so its action is very limited. There was a significative decrease of ear oedema when policosanols in acetone were topically applied. Conclusions: This policosanols mixture has a discrete wound healing action and its anti-inflammatory effect is very limited. 77 FAPRONATURA 2009 Second International Symposia on Pharmacology of Natural Products Varadero, Cuba.

CUBA 1 Introduction: In Cuba exists about 179 medicinal plants which are known because of their diuretic properties according to their traditional use, although in just some cases their effects have been proved experimentally. Objective: To value the diuretic activity attributed to six medicinal plants used by the Cuban population: Ocimum basilicum, Parthenium hysterophorus L, Justicia pectorales, Oreganum bulgharis L, Allium cepa and Citrus aurantium L. Materials and Methods: There were prepared hydroalcoholic extracts from the dry drug of the first four plants mentioned previously, and in the case of the Allium cepa and Citrus aurantium L from their natural juice. There were distributed at random eight Sprague-Dawley male rats in each of the eight homogeneous groups formed: group 1, received 20 mg/kg of furosemide (reference drug); group 2, received NaCl (0.9%), and groups from 3 to 8 received doses of 400 mg/kg, using in all of the cases an 18G intragastric cannula. All the treatments were administrated at a volume of 40 ml/kg. Rats were put in metabolic cages, where it was measured the urinary excretion during the ½, 1, 2, 3, 4, 6 and 24 hours. Results: There was observed that all treated groups increase their urine volume in relation with the negative control group. Urinary excretion, action and diuretic activity were superior in the experimental group Allium cepa, similar to the action of the reference diuretic. Conclusion: This research allowed us to confirm experimentally the popular use of six plants used by the Cuban population.

There are two different receptors in the duodenum for the absorption of the ionic and the heme form of iron and that ferrous state is necessary for ionic iron absorption. Therefore, a formulation containing the two type of iron at the same time could favor total iron absorption if it is capable to preserve the ionic iron in its reduced state. Trofin® is an antianemic natural formulation containing blood caw as heme iron source and proteins. The addition of a ferrous salt to the Trofin formulation may increase its efficacy. Thus, the aim of this work was to evaluate the influence of Trofin® on ionic iron redox status in order to propose a rationale for the inclusion of ionic iron into the Trofin formulation. It were prepared four different combinations of Trofin® +Fe+2 in a w/w relation of: 500:1, 2 500: 1, 5000:1 and 10 000:1, each containing 20 µM Fe+2 from Ferrous Sulphate salt in 50 mM HEPES buffer pH=6,5. We also studied the Trofin® effect on Ferric iron and the influence of pH. The remaining Fe+2 concentration was spectrophotometrically determined at 0, 5, 10, 15, 20, 25 and 30 minutes of Trofin®-iron incubation using 1 mM 1,10 Phenantroline at 510 nm. The oxidative damage of different Trofin® +Fe+2 mixture on brain homogenate of weaned rat was also studied. Trofin® dose dependently caused a diminution of Fe2+ concentration, an effect that was prevented by 78 FAPRONATURA 2009 Second International Symposia on Pharmacology of Natural Products Varadero, Cuba.

The increased in Trofin® concentration significantly decreased the lipid peroxidation in brain homogenate exposed to ferrous iron. These results suggest that the development of new antianemic formulation containing Trofin®+ Fe+2 should be observed cautiously and should comprise amounts of Trofin® below the proportion 500:1 w/w in relation to iron and should contain ascorbic acid. The results also suggest for the first time an antioxidant effect for the Trofin formulation.

San Lázaro y L, Ciudad Habana 1 Diabetes is a serious problem of health at world for its high prevalence and its complications. Its development and complications on various organs have been attributed to increased oxidative stress. Recently several studies have been reported a relationship between the zinc functions and the oxidative stress associated to diabetes. This has been associated among other factors to changes in the zinc metabolism that modify the insulin answer and metallothionein antioxidative properties, which is very rich in cysteine and is an excellent scavenger of reactive oxidative species. The homeostasis of Zinc is proposed as a key factor in the onset and/or progression of the DM, observed by numerous examples in animal models and in clinical studies. In Cuba have been designed and developed several modified natural zeolites. One of them is the e zeolitic natural product activated with zinc ions named ZZ. ZZ performs as a control releaser of zinc. Taking into account we studied ZZ antihyperglyceamia effect and its effects on oxidative stress markers levels.Five groups of rats were classified as follow: (1) positive control using as a diabetes inductor, (2) non-diabetic control treated with vehicle solution (3) ZZ group receiving 21 treatments (500 mg/kg), (4) ZZ group receiving 21 treatments (1000 mg/kg), (5) ZZ group receiving 21 treatments (1500 mg/kg). The ZZ treatment improved glycemic control and prevented oxidative stress. The results of this study show that repeated administration of ZZ might play a role in the control of diabetes and its complications.

E-mail: [email protected] Polyphenols are a large number of family compounds which are well represented in many plants all over the world. Their pharmacological properties of many of them have been studied and it is well recognized the antiinflammatory, antioxidant, antimicrobial, among other biological activities. In particular the wound healing process starts with an inflammatory phase which is accomplished of reactive oxygen species (ROS) increasement; so to study the effect of polyphenolic compound on the REDOX mechanism involved in this process was the goal of the present research. Rhizophora mangle (L.) bark aqueous extract and its major component, high molecular weight polyphenols fraction, were evaluated for antioxidant and wound healing properties on a rat (SD) model of aseptic wounds.

Different markers representing REDOX balance during the wound healing process were also measured in the new formed tissue at 0, 3, 7 and 14 days comparing the evolution in treated and non treated wounds: Dismutase Superoxide (SOD), Catalase (CAT), reduced Glutahione (GSH) and malonildialdehyde (MDA). Results showed that the wound area was reduced in that treated with both the extract and R. mangle fraction comparing with control groups (p< 0.05). Also the activity of antioxidants enzymes SOD and CAT, and GSH concentrations were increased in presence of the extract, its fraction and positive control (Ascorbic acid) compared to non treated control group (p< 0.05); while the MDA concentrations was decreased in these groups (p< 0.05). This is the 1rst report showing the pharmacological activity of Rhizophora mangle (L.), modifying the REDOX balance of the wounds evolution with benefit for the healing process due to the increasing of the antioxidant biomarkers and the decreasing pro-oxidant indicators in the wound.

As a result the search for new treatment products from natural sources constitute an important task of modern pharmacology. The present study evaluated the anti-tumour effect of the aqueous extract of the Mangifera indica L. stem bark extract (MISBE) and of its main component mangiferin, on the tumor cell lines 3LLD/122 and U1906. In anti-proliferative studies, MISBE showed little toxicity on the 3LLD/122 cell line, with a IC50 of ≈ 216.7 µg/ml, and the mangiferin did not 80 FAPRONATURA 2009 Second International Symposia on Pharmacology of Natural Products Varadero, Cuba.

It was determined, using flow cytometry 24 hours after treatment, that MISBE, as mangiferina, did not induce apoptotic mechanisms of death; nevertheless, both products did induce necrotic mechanisms. 48 hours after treatment, MISBE was able to induce apoptotic mechanisms. It was obtained in in vivo studies that MISBE (25, 50 and 100mg/Kg) and mangiferin (5, 10 and 20mg/Kg) inhibited significantly the tumor growth in the dorsal line of mice C57BL/6, 24 days after the challenge. In the treatment with both products there was a higher percentage survival rate 45 days after the challenge. These results show that both products could be considered for use concurrently with conventional cancer treatments.

For it, a growing interest exists in developing new products with radioprotective character that diminish the adverse effects of the radiotherapy. The aminotioles (as the amifostina) are the agents that more they have been used with this end. However, the continuous employment of this type of compounds causes severe secondary effects. For this reason, the current tendency is focused to obtaining radioprotective agents from natural sources. The natural product, Vimang, that one obtains from the bark of Mangifera indica L. constitutes an interesting candidate for the evaluation as radioprotective if one keeps in mind that the pharmacological studies carried out until the moment, corroborate its effectiveness like antinflamatorio, analgesic, inmunomodulador and characteristic antioxidante all described for an ideal radioprotector. The execution of the SOS Chromotest indicated that the extract is not genotoxic in the analyzed range of concentrations (50, 250, 500 and 1000 µg/mL); in presence or not of metabolic activation. Additionally, it was determined that the Vimang presents character radioprotector on the genetic material, when it is used to a same concentration or superior to 250 µg/mL. Evaluations carried out in human red blood cells indicated that the evaluated product inhibits the lipid peroxidation, when it is used between 500 and 1000 µg/mL and it diminishes the damages caused to the mitochondrion and its enzymes, when being used in a similar range of concentrations. These results demonstrate that the extract is able to protect the cellular structure at several levels: nuclear material, cellular membranes and mitochondrial enzymatic systems, of the damages induced by the gamma radiation.

The main DNA lesions induced by UVB light, cyclobutane pyrimidine dimers (CPDs) and 6-4 photoproducts (6-4PPs), are considered the major causes of apoptosis and mutagenesis induction. Also this mutagen increases cellular reactive oxygen species levels (ROS). One approach to protect human skin against UVB harmful effects is the use of natural products as photoprotectors. In this sense, the aim of the present investigation was to evaluate Phyllanthus orbicularis HBK extract properties in the protection of human cells against UVB light-induced damage. DNA repair proficient and deficient fibroblasts (MRC5-SV and XP4PA) were used as experimental models. The damaging effects of UV were evaluated through clonogenic cell survival and apoptosis induction, while DNA repair was determined by the removal of cyclobutane pyrimidine dimers. The results indicated that an extract of P.orbicularis protects human cells against UVB light-induced damage in concentrations where no light absorption is observed; this protection being mainly related to positive modulation of cell ability to repair this type of DNA damage.

Adequate chemoprotection by means of vegetable extracts is a new strategie essential to control harmful overexposure to solar UV. In this study we evaluated the photoprotector capacity of aqueous extract of Cymbopogon citratus (DC) Staff against cyclobutane pyrimidine dimers (CPD), the most frequent photolesions induced by UV radiation. We use supercoiled circular plasmid DNA model to evaluate the photoprotection by the extracts before, during, and after having irradiated with UVC 200J/m2. These studies showed that C. citratus presents photoprotector properties against genotoxicity of UV that could be sustained by different action mechanisms.

Endophytes may contribute to their host plant by producing a plethora of substances that provide protection and survival value to the plant. Recently, these compounds, once isolated and characterized, may also have potential for use in modern medicine, agriculture, and industry. Endophytic fungi from 10 plant species were isolated. Identification was based on colony morphology, hyphal morphology and reproductive structures when present. Liquid medium were inoculated with fungi culture and were allowed to grow at 25°C until the glucose level was 0. The filtered broth and the mycelium were extracted with organic solvents. Chromatography methods were used to obtain fractions and purify the antimicrobial compounds. Antimicrobial activity of extracts was evaluated again bacteria and fungi using diffusion agar method. 42 isolations of fungi were obtained. The predominant endophyte genera found in all plants were Alternaria, Pestalotia and Phomopsis. Alternaria and Phompsis produced a variety of antimicrobial compound. Extracts from the filtered broth showed greater antimicrobial activity than extracts made from the mycelium. Endophytic fungi studied showed a varied production of secondary metabolites with antimicrobial activity. PPP-28 ANTILEISHMANIAL ACTIVITY OF BIXA ORELLANA.

Actually, leishmaniasis is prevalent in 88 tropical countries throughout the world and it estimated that 1.5 million to 2 million reports of new cases occurs annually. Control of leishmaniasis relies on chemotherapy, but the availability and effect of conventional drugs are limited. Although exist some drugs, these are toxic, expensive and require long-term course of therapy. The Program of Tropical Diseases of WHO considered the investigation of plant as essential priority for the treatment of Leishmania. In the present study the antileishmanial activity of alcoholic extract of Bixa orellana against Leishmania amazonensis was evaluated. 83 FAPRONATURA 2009 Second International Symposia on Pharmacology of Natural Products Varadero, Cuba.

In the in vivo assays female of BALB/c mice was used. In the in vitro assays the extract showed CI50 values of 22.05 y 9.1 µg/mL against promatigotes and amastigotes respectively, while a moderate toxicity on macrophages from BALB/c mice was observed. At a dose of 100 mg/Kg/day the extract was effective when administered during 15 days by intraperitoneal route to BALB/c mice experimentally infected.

Monzote L1, García M1, Scull R2, Miranda M2 Departamento de Parasitología, Instituto de Medicina Tropical “Pedro Kourí”, Cuba. 2 Instituto de Farmacia y Alimentos, Universidad de La Habana, Cuba. 1 Leishmaniasis defines a group of endemic diseases caused by species of the genus Leishmania. Due to the high death and morbidity rates the World Health Organisation has considered it as a major tropical disease. New anti-leishmanial drug discovery is a need as currently available therapy includes only parenterally administrable drugs, requires hospitalisation for long treatment periods, is expensive, is potentially toxic and parasite resistance has emerged as a further problem. About 60% of patients use traditional medicine and that have served as source to search for new therapy choices. In the present work we tested the efficacy of essential oils extracted from Piper auritum (commonly known as “caisimón”) on Leishmania. The oil extract was characterised by gas chromatography – mass spectrometry. Major component was safrole (87%). The oil of Piper was active against promastigotes of L. major, L. mexicana, L. braziliensis y L. donovani, with an 50% inhibitory concentration (IC50) below to 100 µg/ml. The IC50 against amastigotes of L. donovani was of 40 µg/ml and against peritoneal macrophages from BALB/c was of 106 µg/ml, showing the better selectivity index. These results show the potential of essential oils from Piper auritum as anti-leishmanial therapy.

In previous research we studied the antibacterial, antifungal and antiparasitic activity of plant species belonging to the SIPARUNACEAE family and whereas Siparuna bífida is a potentially exploitable specie since its essential oil showed an interesting antiparasitic activity, in this work it was considered to study the effect caused by seasonal variability in the composition and biological activity that presents the essence of the Siparuna bifida from the Valley of the Sacta-Carrasco (Cochabamba-Bolivia). Random samples were collected from the aerial parts of plants in the months of October (full flowering) and December (fruiting). Essential oils were obtained from fresh material by the water steam extraction method (Hidrodiffusion), reaching yields between 0.1 and 0.3% on wet basis. GC and GC-MS analysis allowed the identification of the majority components of essential oils, those that were put under an evaluation “in Vitro” to determine their antiparasitic activity in Chagas (Tripanosoma cruzi), Malaria 84 FAPRONATURA 2009 Second International Symposia on Pharmacology of Natural Products Varadero, Cuba.

The chromatographic profiles of the essences obtained in both months are similar, being basically represented by terpénics hydrocarbons (56%) and oxygenated terpenes (44%). Quantitative variations in single some components are observed such as: biciclogermacrene (15.0 to 7.3%) and -bisabolene (19.2 to 15.8%). Although the essential oils obtained at the time of flowering and fruiting, present activity before the 3 studied parasites, the essential oil obtained from flowering stage exhibits a greater activity in front of the parasites that produce Malaria and Chagas. The essence of better quality would be obtained with plants in full bloom; due to these variations it would be interesting for future works, the analysis of the ontogenic effect on the composition of the essential oil and therefore in the biological activity of the vegetal specie.

In this scenario, the search for antiviral metabolites from natural sources represents a promising strategy. In this work, the chemical composition and antiviral activity of extracts from Ageratina havanenis (Family Asteraceae) stems and leaves were investigated. Citotoxicity of the test extracts were assessed by means of the MTT colorimetric assay and antiviral activity was determined as a function of viral-induced cytopathic effect (CPE) reduction under a light microscope. Viruses used in this study included Poliovirus 1, Coxsackievirus A16, Coxsackievirus B5, Echovirus 9, Rabbit vesivirus (RNA viruses) and Herpes Simplex Virus type 2 (DNA virus). Ethanol extract from stems and ethanol extract from leaves were effective against Poliovirus 1 (selectivity indexes 3.2 and 2.1, respectively) and HSV-2 (SI 2.6 and 2.2 respectively), while ethanol extract from leaves was further active against Coxsackievirus B5 and Coxsackievirus A16 (SI 3.2 and 3.3 respectively). The higher inhibitory activity was recorded for the ethanol extract from stems against Rabbit vesivirus (SI= 4.7). Triterpenoids, steroids, flavonoids and glycosides were the major constituents detected in A. havanensis extracts.

In this work, extracts obtained from stem and leaves from this plant, with different solvents (ethanol: EtOH, n-butanol: nBtOH, ethyl acetate: AcOEt), were screened for inhibitory activity against Rabbit Vesivirus (RaV) (Family Caliciviridae). 1 Citotoxicity of the test extracts were assessed by means of the MTT colorimetric assay and antiviral activity was determined as a function of viral-induced cytopathic effect (CPE) reduction under a light microscope. The time of inhibition was studied using a time-of-addition experiment. Virucidal assays were carried out in order to assess the extracellular virus-inactivating capacity of the plant extracts. Selectivity indexes (SI) ranged from 2.3 to 4.7. The strongest inhibition was recorded for extracts obtained from stems. A. havanensis affected intracellular viral replication processes rather than early events, as it could be demonstrated by time-of-addition assay. No virucidal effect was found for the plant against this virus, since viral suspensions remained infective after treatment with 8-fold EC50 extract concentration, no matter the time of exposure employed. The mechanisms underlying intracellular viral inhibition merit further research.

The high toxicity of synthetic anti herpes compounds and the lack of an efficacious vaccine have emphasized the search for new inhibitors among natural products, particularly from plants. In this work, the antiviral activity of Phyllanthus orbicularis aqueous extract was evaluated in vitro against a virus panel including acyclovir (ACV)-sensible and resistant HSV-1 and HSV-2 references strains and clinical isolates, as well as against HCMV reference strain AD169. Citotoxicity of the test extract was assessed by means of the MTT colorimetric assay and antiviral activity was determined as a function of viral-induced cytopathic effect (CPE) reduction under a light microscope. The time of inhibition was studied using a time-of-addition experiment and virucidal assays were carried out in order to assess the extracellular virus-inactivating capacity of the plant extract. Anti HCMV activity was further confirmed by a real time PCR assay. P. orbicularis was effective against all studied viruses and selectivity indexes (SI) ranged from 8.7 and 40.8. The product was effective from the very early events of viral infection and a strong virucidal effect was achieved since viral suspensions titres decreased by 1 log10 or more after treatment with the extract. In the presence of P. orbicularis, the concentrations of HCMV viral DNA in infected-cultures supernatants were at least 5-fold lower when compared to that of untreated infected cells. 86 FAPRONATURA 2009 Second International Symposia on Pharmacology of Natural Products Varadero, Cuba.

Email: [email protected] Medicinal plants have been widely used for the treatment of infectious diseases. In Cuba several plants are commercially available. In this work the antiviral properties of plants extracts derived from three medicinal plants used in Cuba: Calendula officinalis L., Psidium guajava L. and Eucaliptus spp., against the hepatitis B virus were evaluated at subtoxic concentrations in the in vitro PLC/PRF/5 system or Alexander cells, a cell line expressing constitutively the virus surface antigen (HBsAg). The cell viability was measured by the MTT method and the mean cytotoxic concentration values (CC50) were calculated. The antiviral activity was considered as the ability to inhibit the HBsAg production during 48 hours of treatment and expressed as IC50. The relation between CC50 and IC50 represented the Selective Index (SI). Eucalyptus spp. showed a lower toxicity in the cells, followed by Psidium guajava L. and finally Calendula officinalis that had a much higher toxicity than the previous extracts. The data obtained showed an inhibitory activity in the case of the Eucalyptus extract (IS=25.21) higher than the guava extract (IS=6.70), whereas Calendula did not show any inhibition in the assayed concentrations, which proves the absence of the searched activity in this extract. The behaviour of the HBsAg intracellular produced after the treatment of the cells with Eucalyptus and guava is similar to those obtained for the extracellular antigen.

The antiviral properties of the species of Phyllanthus are attributed to the presence of phenol type compounds. These inhibit the DNA polymerase and reverse transcriptase. The study examines the correlation between the concentration of phenolic compounds and the reduction of surface antigen of hepatitis B viral (AgsVBH) cuban species with reported antiviral action. Materials and Methods. Aqueous extractions were made of plant material. Were measured concentrations of phenolic compounds c(PhC) by colorimetric method and were standardized extracts concentrations (0.1 to 0.7) mg / ml. To each extract was determined the activity by reducing of AgsVBH in serums from seropositive patients (ΛAgsVBH) for the interval (1/800 to 1/51 200) using the ELISA technique. Correlated pairs by the method of least squares (R). The correlation coefficients obtained were subjected to analysis of variance. Results. The increase in c(PhC) is inversely and linearly proportional to the reduction of antigen (ΛAgsVBH), because (R) 2 are in ranges from 67.73 to 51.12 with an analysis of variance results P < 0.05. This proves the metabolite-bioactivity relationship and define the coefficient of inhibition (Cinh) as the slope of the straight line correlation (ΛAgsVBH) vs c (CPhC). Conclusions The coefficient of specificity of inhibition (Cinh) AgsVHB lets compare the magnitude of the effectiveness of antiviral action in vitro of species of Phyllanthus. The highest value corresponds to the root of P. chamaecristiodes. 87 FAPRONATURA 2009 Second International Symposia on Pharmacology of Natural Products Varadero, Cuba.

E-mail: [email protected] Currently investigations in the world look for new and effective proposals for the management of bacterial infections. In studies already carried out with Petiveria alliacea L., it was observed that plant extracts do not undergo microbial contamination when they are exposed to uncontrolled storage conditions. This fact led to the antimicrobial evaluation of 8 total extracts of the leaf: two of them in the ratio of 1:4 were prepared from the dried leaf and ethanol 30% as the solvent; the remaining 6 were prepared using fresh leaves and ethanol 30%, 80% and isopropylic alchohol as solvents, in the ratio of 1:4 and 1:6 respectively. For the antimicrobial evaluation, the Kirby-Bauer disk diffusion method was opted using the following different strains of reference: Staphylococcus aureus, Escherichia coli, Enterococcus faecalis, Pseudomonas aeruginosa and Candida albicans. The results showed that only antibacterial activity was obtained with a zone of inhibition of more than 6mm. in 3 of the soft extracts: 2 with isopropylic alchohol (1:4 and 1:6) and 1 with ethanol 80%(1:6), against Staphylococcus aureus and Escherichia coli; thereby corroborating that heat and drying of the plant destroys the components with antimicrobial activity in anamú1 and that non-polar solvents are more adecuate for the extraction process of the components with the mentioned activity. The soft extracts with isopropylic alchohol possess higher antibacterial activity. Antifungal activity was not obtained on the assayed extracts. 1. Seokwon K., Roman K., Rabi A. M.

Among the chemical groups have been isolated alkaloids, flavonoids, triterpenes. The first stage in the study of any product as a potential antiviral is a quantitative assay to assess their effects on cells or cytotoxicity, expressed as the concentration value that causes cell damage evident at the 50% of the treated cultures cytotoxic concentration median(CC50). Knowing this value allows subsequent use or lower concentration for testing antiviral activity. In our work, we evaluated the cytotoxicity of 11 chemical fractions from of the specie Erythroxylum minutifoluim. The experimental design consisted of determining the Cytotoxicity Concentration Median (CC50) on Vero and FPH cell lines. The effect was determined by the calorimetric method of MTT. The fractions EM-C and EM-CM at concentrations of 778.05 µg/mL and 792.63 µg/mL, respectively, showed a cellular viability higher than 90% in the Vero cell line and the concentrations of 863.72 µg/mL and 898.06 µg/mL in the FPH cell line. While for the Fractions P-FA, FA, FA-1, FA-2, FP, EX1, EX2, EX3 and P remained above 90% until a concentration of 1000 µg/mL. The behavior of the variables in the 11 fractions, showed no statistically significant differences between the two cell lines for p> 0.05, for that reason it possibility use both cell lines for antiviral assay . Fractions P-FA, FA, FA-1, FA-2, FP, P, EX1, EX2 and EX3 were not toxic up to a concentration of 1000 µg/mL in the cell lines used.

Its study is a wide field of research since those toxins are commonly very specific and potent, and therefore usefull tools in electrophysiology and promising drugs for therapeutics. Subjects: The aims of this work were to purify the Physalia physalis crude extract and to determine the effects of the low molecular weight fractions on a model of insulin secretion of beta cells from Wistar rats pancreas. Materials and Methods: The Physalia physalis crude extract were purified by a gel filtration using a Superdex 200 HiLoad 60/30 column in an AKTA-FPLC system (Amersham Pharmacia Biotech). Mass spectrometry MALDI-TOF (Bruker Daltonics) and RP-HPLC (Ultrasphere-DABS C18 column, Agilent 1100 system) were assessed to each fraction collected from gel filtration. The biological activity of low molecular weight fractions was assessed in a reverse haemolitic plaque assay on primary cultures of pancreatic beta cells from male Wistar rats. Results: Fractions IV and V from gel filtration increased the secretion index at both glucose levels (5.6 mM and 16.5 mM) whereas at low glucose they exert their effects by increasing the inmunoplaque area but also recruiting a population of non secretory beta cells.

E-mail: [email protected] 2 National Centre for Animal and Plant Health (CENSA) Carretera de Jamaica y Autopista Nacional, San José de las Lajas, La Habana, Cuba 1 The acute respiratory distress syndrome (ARDS) is caused by a pulmonary inflammation with plasma transudate and destruction of pulmonary surfactant, causing a disruption in the exchange of gases with high mortality, the application of exogenous surfactant improves oxygenation but has not yet been able to demonstrate convincingly reduced mortality or other variables such as length of stay in ICU or mechanical ventilation. Our objective was to evaluate the effect of Surfacen in low dose and sustained for three days on the oxygenation of patients with ARDS. To this end we conducted a controlled randomized, multicentre clinical trial, in 39 adult patients of whom 21 were treated with 100 mg Surfacen 3 times for 3 days and 18 remained only with mechanical ventilation. The response was assessed as positive when the ratio PaO2/FiO2 ≥ 200 at the end of treatment, we also considered the followings evaluations: gasometry, Clinic and X ray, safety, mortality, days of stay in ICU, days of intubation and days with mechanical ventilation. The results showed a better response indicator PaO2/FiO2 in the treated group (P = 0.0560) and if included 3 patients who did not reach the end of the evaluation period this difference was maintained (P = 0.0411). There were no differences in mortality (P = 0.296) among groups, 11 patients died in the Surfacen group and 6 in the control group, however the causes of death were not by ARDS but because the basic pathology. The treated group showed a decrease (P = 0.0341) of 7.23 in the days of endotracheal intubation, there was not difference in the days of mechanical ventilation (P = 0.132) or stay in the ICU (P = 0.108) although there was a tendency to be better in the group treated with Surfacen. We conclude that the use of surfactant in ARDS improved oxygenation in patients with lower FiO2 requirements, reduced the time of endotracheal intubation and had a good safety.

Valdés Carrillo R*, Trasanco Delgado M*, Becerra N*, Tur Behar R** *“Abel Santamaría Cuadrado”, Provincial Hospital. Pinar del Río. **Servier Laboratories. Medicaribe SA. Email: [email protected] Introduction: Lepidium Meyeni (MACA) is used from ancient times due to its supposed aphrodisiac properties. The present study is aimed at determining if the administration of MACA during 12 weeks improves the sexual desire in males over 50 years of age being treated with this product or placebo and the blood reproductive hormone levels. Method: A randomized - double blind controlled by placebo design. Forty males between 50 and 59 years old who were given 1500 mg of gelatinous MACA or placebo over 12 weeks were studied. They were valuated at 0, 2, 4, 8 and 12 weeks of treatment, valuating the sexual desire using a questionnaire and the levels of LH, FSH, prolactin (using the Irma method), testosterone and estradiol (E2) by RIA. Results: The analysis of logistic regression shows that MACA has an independent effect on sexual desire at 8 and 12 weeks after treatment. The levels of hypophyseal reproductive hormone (LH, FSH) after and before treatment were not changed during the 12 weeks using this product. Prolactin dosage showed a light and a non significant increase (536, 5 ± 212 ng / ml) with any anxiety or depression symptoms as a result of hyperprolactinemia. The levels of testosterone had a non significant increase. (5, 33 ± 4, 37 mU / ml). Estradiol (E2) showed a decreased in the values which are considered in males. (1, 09± 0, 74 ng /ml). Conclusions: It is proved that in males supposedly healthy, MACA improves the sexual desire not affecting the hypophyseal reproductive hormone levels, testosterone showed high levels (a transitory hyperprolactinemia was observed using this product). Further studies for validating which was found in the present study are needed. 91 FAPRONATURA 2009 Second International Symposia on Pharmacology of Natural Products Varadero, Cuba.

An open, parallel, controlled and randomized clinical trial was made in 60 patients with a diagnosis of squamosa and corporis tinea pedis, coming from the consultation of Dermatology of the "Camilo Cienfuegos" Hospital of Sancti Spíritus, with the objectives of evaluating the clinical effectiveness, as well as the security of the product. Two groups of 30 patients were made up. Dermofural 0,15% was applied topically in ointment to the first one and ketoconazol 2% to the control, in both for a period of 6 weeks of treatment. The clinical and mycological evaluation variables were used at the beginning and the end of the treatment, establishing the results in cured and not cured. We observe that of a total of 39 patients that finished the final evaluation in both groups. 21,1% of cure was obtained with dermofural and 15% with ketoconazol; of these 72,2% had negative mycotic cultures with the drug in study and a 85,7% with the control. A percent of cure of 11,1% was found with dermofural and 19% with ketoconazol with a signficant difference. A total of 10 adverse events occurred in 5 patients treated with dermofural (27,7%) and none with the control product. The most common reactions were pruritus and erythema, classified as severe and related with the product in the first case, and as slight and not related in the second. It is concluded that dermofural is a product with an antimycotic effect and with a low toxicity, useful for the treatment of these affections.

[email protected] The medicinal plants constitute important resources in rural communities, where the traditional medicine occupies a central role as a strategy of primary attention of health (Tabuti et al., 2003; Bermúdez, 2007). This study aims to register the traditional uses and estimating the relative importance of the medicinal plants in rural communities, of the Andean piedmont, Venezuela. The ethnobotanic inventory was conducted in three communities of Monay's Plains, Trujillo state. The ethnopharmacologic information was registered utilizing the TRAMIL survey (Robineau, 1995), while the relative importance was evaluated utilizing index of level of significant use (Robineau, 1995) and pharmacologic versatility (Bennett and Prance, 2000). 118 species, which belong to 106 genders and 54 families were registered, those were utilized to treat 72 local problems of health, within 16 categories of diseases. A significant correlation between the local incidence of the categories of diseases and the average of utilized plants to treat them was found. The majority of the traditional treatments are prepared with the aerial parts of the plants by means of decoction, to be administered orally. Only 05 species evidenced significant uses, while 10 presented high pharmacologic versatility. The results suggest than at this region, the use of plants still constitutes an alternative in the primary attention of health, as it becomes evident in the number of registered species and the existent relation between the riches of the local pharmacopoeia and the incidence of diseases.

The ethnopharmacological information was registered utilizing the TRAMIL survey (Robineau, 1995), the relative importance was estimated by means of index levels of significant use (Robineau, 1995 ) and the pattern of distribution of the traditional knowledge was evaluated using Chi-square test ( p 0.05 ). 37 species, which belong to 28 botanical families, were utilized to treat 22 local problems of health, within 08 categories of diseases. The majority of traditional treatments is prepared with the aerial parts of the plants by means of decoction, and is to be administered orally. Only 04 sorts evidenced significant uses. No differences were found between the averages of the number of plants quoted by sex, but older people, above 50, possess a higher level of traditional knowledge. These results suggest than in urban communities of the Trujillo state, the utilization of medicinal plants for primary attention of health has died off, as compared with rural communities, and that the traditional knowledge is distributed preferentially among elderly population.

A total of 136 patients were enrolled (88 patients elegible). A clinical and bacteriological diagnosis was made as a method of confirming the disease. In the infected areas of the skin a topical ambulatory treatment with mupirocine (control group) or ozonized oil was applied for 10 days. An initial, intermediary (after 5 days), and a final (after the treatment) assessment was completed. A clinical and bacteriological assessment was made for determinate the efficacy of each treatment. There were analyzed the costs of each treatment data outlining as objective the determination of the most efficient alternative for the therapy of impetigo. Efficacy and the most direct costs in both therapies were evaluated and it was carried out a pharmacoeconomic analysis type cost-efficacy. As result, the treatment with the national drug was effective as an adequate therapy in the management of patients with impetigo, and the other hand, it turned out to be the alternative of more efficiency in this therapy with a significant difference in cost reduction (about 30 % than mupirocin cost). With the use of national product is significativaly reduced the cost of this pharmacotherapy. 95 FAPRONATURA 2009 Second International Symposia on Pharmacology of Natural Products Varadero, Cuba.

P.O.: 50200 E-mail: [email protected] Introduction: it is well known that is feasible the support of natural drugs to synthetic and semisynthetic ones and there is a universe of medicinal plants used traditionally in Cuba which are attributed hypoglycemic activity based only in informations of empical use which means whitout any scietific experimental evidence, some of those plants are: Catharantus roseus, Rhoeo spathacea, Parthenium hysterophorus and Orthosifon aristatus. Materials and Methods: Plants were cultivated, colected and the extracts were made according to the regulations of Agriculture Ministery and later the extracts were determined their phytochemical composition. Hypoglicemic effect was studied in two groups (Treated and negative control: SSF 2 ml/animal of 10 animals each one) of normoglycemic male SD rats, glycemia levels were measured before and after the three days administration of the aequous extracts (400 mg/kg BW based on total solids). Acute oral toxicity was carried our according to the alternative CTA limit dose method (2000 mg/kg BW) as stated in OECD Test guideline 423. Results: the extracts showed no hypoglycemic effect a the dose essaied when compared to non treated animals, coinciding with the existing ethnomedical data and showed no symptoms or signs of toxicity. Conclusions: this four plants have no hypoglycemic activity and can be considered as non toxic under the experimental conditions applied.

Under the name of Erythroxylum or Erythroxylon like genus, in Cuba are described 22 species. Some of these plants have been used in the traditional medicine like anti-inflammatory in the cure of respiratory diseases. In this work the cytotoxic and genotoxic potential of an etanolic extract of Erythroxylum minutifolium var Griseb (ExM) was analized using a modified protocol of the SOS Chromotest and the Comet assay. Results showed that E. minutifolium extract was cytotoxic using E. coli strain PQ37 at the concentration of 200ug/ml in presence and absence of S9 mix activation system.The extract no induced primary DNA damage in the cells of E. coli PQ37 at neither of the tested concentration using the SOS Chromotest assay. However, at the concentration of 100ug/ml in presence of metabolic fraction and 200ug/ml without and with addition of metabolic activation system, the extract was genotoxic in the Comet assay. Results obtained can be influenced by the extract composition. Further investigations regarding dose-response-relationships and other aspects relevant for extrapolation to human exposure seem necessary. 97 FAPRONATURA 2009 Second International Symposia on Pharmacology of Natural Products Varadero, Cuba.

E-mail: [email protected] Centro de Aplicaciones Tecnológicas y Desarrollo Nuclear (CEADEN). The seaweeds have attracted much attention as a source of natural preparations, which could find applications in the cosmetic industry, food technology and biomedicine. Bryothamnion triquetrum, Halimeda incrassatta and Halimeda monile are seaweed species whose aqueous extracts possess antioxidant properties. Nevertheless, as preclinical requirement, the employment of these natural sources should be studied from the genotoxic point of view. Because the knowledge about genotoxic properties of this seaweeds is limited, in the present work were analyzed the genotoxic effects of the aqueous crude extracts of the referred seaweed species. SOS chromotest assay, in its fluorescent variant, was used as genotoxic test. E. coli PQ37 cells were treated with different concentrations (0.1-2 mg/mL) of the extracts, during 30’. Then, the activity levels of β-galactosidase and alkaline phosphatase were taken as indicative of genotoxicity and citotoxicity, respectively. The results evidenced that the extracts were not genotoxic in this experimental conditions. Moreover, in E.coli cells treated with Halimeda monile extract, were observed SOS-induction factor levels significantly smaller that the obtained in not treated cells. 2 PTS-06 TOXICOLOGICAL AND PHARMACOLOGICAL PROPERTIES OF A LOW MOLECULAR WEIGHT FRACTION FROM ZOANTHUS SOCIATUS (CNIDARIA) ASSESSED IN OF-1 MICE.

The high affinity and specificity of such toxins make them interesting in basic and applied research. Objective: To purify Zoanthus sociatus crude extract by gel filtration (Sephadex G-50), to assess the effects of the low molecular weight fraction by a behavioral test in OF-1 mice and to determine the mortality-dose curve of acute toxicity. Materials and Methods: The specimens of Zoanthus sociatus were collected in the pools of the Nacional Acuarium of Cuba in September of 2008. The total body was homogenized in a Waring-Blender by autolysis in distilled water. The crude extract was filtered and then centrifuged, the supernatant was then lyophilized. After the purification by gel filtration (Sephadex G-50), a RP-HPLC (Ultrasphere-DABS C18 column, Agilent 1100 system) was assessed to the low molecular weight fraction, which effects were assayed by an Irwin test in OF-1 mice and its LD50 was calculated. Results: The low molecular weight fraction contains peptidic compounds mostly, and it also represent the major component of the crude extract. The pharmacological effects depend on the dose and the inoculation pathway; by the systemic way, the alterations are mostly autonomic. The LD50 was of 132 mg/Kg when it was inoculated intraperitoneally, and it reaches 100 % of lethality at a dose of 150 mg/Kg. Conclusions: Low molecular weight peptides in Zoanthus sociatus crude extract have neuroactive an autonomic effects depending on the dose and administration pathway and it is a moderate toxic fraction when it is administered intraperitoneally in mice. 98 FAPRONATURA 2009 Second International Symposia on Pharmacology of Natural Products Varadero, Cuba.

This case report is about the successful treatment of cats suffering from jaundice. Icterus (jaundice) is meant for the yellow pigmentation in the blood and tissues. It mostly occurs due to high levels of chemical bilirubin in blood. The presence of fleas, lice or ticks is the predisposing factor for jaundice in animals. In cats, in addition to these factors, other risk factors include infection with feline leukemia virus or feline infectious peritonitis virus. Two cats (with a history of jaundice) were brought to the clinic of medicine and surgery, University of agriculture, Faisalabad-Pakistan. Firstly, the diagnosis was confirmed by physical examination and by performing laboratory examinations for complete blood count and liver function test. After diagnosing, these cats were treated with Chellidonium® drops (a homeopathic medicine) 30 potency through oral route, two drops three times a day for 10 days. During this duration the supportive therapy was also continued. After 10 days, complete blood count and liver function tests were again performed which showed positive results towards recovery, the mucous membranes and sclerae became normal and animal showed good recovery in its health status as well. This lead us to the conclusion that icterus in animals could be overcome with the help of Chellidonium® drops orally along with supportive therapy parentally.

Email: [email protected] 1 A prospective, descriptive study, with inferential analysis was carried out to evaluate the therapeutic effect of acupoint injections with minimal doses of steroids in the treatment of joint pain resistant to other therapeutic procedures. A total of 74 patients from the Provincial Center of Traditional and Natural Medicine “Dr. Mario E. Dihigo” of Matanzas were included, all of them having received previous allopathic and CAM treatments, including Acupuncture. Visual Analogical Scale (VAS) was applied to evaluate pain intensity. Traditional and Clinical diagnoses were determined for each patient and allopathic drugs consumption was also evaluated. Based on pain topography local acupoits were punctured with minimal doses of steroids. Initial pain score was 7.9±0.53 for 74 patients while at the end it was 1,74±0,6 for only 9 patients. Only these 9 patients ended with allopathic drugs consumption but at lower doses. According to these findings acupoint injections with minimal doses of steroids is a recommended procedure for treating joint pain resistant to other treatments.

An on-going randomized-triple blinded clinical trial was carried out to evaluate the haemostatic effect of ultra high dilutions of Phosphorus in the surgical patient. Prostatectomy, hysterectomy and knee surgery were the three surgical procedure included. Only 30 patients were evaluated as a preliminary sample, divided into three groups which received Phosphorus 200 CH, Phosphorus 1000 CH and a placebo. Haematocrite, Coagulation and Bleeding time were performed to every patient, previous and after medication, except Haematocrite which was performed after surgery. Statistical tests to compare average of non-independent samples and KruskalWallis test were applied to the clinical and laboratory data obtained. Even when the haemostatic effect was not statistically demonstrated, a lower Coagulation time with statistical significance was observed for the group treated with Phosphorus 1000 CH and both Phosphorus groups had a lower Bleeding time but without statistical significance. No differences on blood loss were observed and it is recommended to keep on increasing the number of patients for this trial.

In this investigation, using a solar dryer, the solar drying curves were built in actual hours and in equivalent hours of sunshine to the leaf of three medicinal species: the white Basil (Ocimum basilicum L.), is employed as antispasmodic, Melissa (Melissa officinalis L.) used as a sedative and Malojillo or Caña santa (Cymbopogon citratus D.C.), consumed mainly as antihypertensive and anti-inflammatory. These species are commonly used, produced and marketed in the state of Trujillo, andean region of the Bolivarian Republic of Venezuela. The kinetics of moisture loss as a function of time is plotted, in three periods, until the material reached a humidity below 10%, with a temperature no higher than 45 Celsius degrees in the working fluid. The temperature in the drying chamber was regulated by a curtain down on the collector. Each test was replicated three times. The drying time was set as the time required to reach the recommended moisture content of 10% and was obtained by interpolation in the drying curves.Some parameters were determined to assess the energy converter. To generate the drying curves and compared those with the conventional drying outdoors reported in the literature cited, was found a significant reduction in drying time, in addition, it has the advantage of obtaining a better quality product because the material is not exposed to direct sunlight. In assessing the solar dryer was found a good control of the drying temperature for all cases tested.

Water and food salt (99.8% sodium chloride) were used as electrolyte solutions and at the same time as an extractant solution. The method was tested on caraway fruits as a source of carvone and limonene as the main components. The carvone also has a medical relevance, various works in the medical field were recently reviewed and discussed by Carvalho et al., 2005. These authors described how carvone may lead to better drugs and to an effective treatment for candidal infections. It was also used in the stereoselective synthesis of the marine antitumor agent eleutherobin, this was proved a class of potential chemopreventive anticarcinogenic agents and it was found to be helpful in the prevention of cancer. 102 FAPRONATURA 2009 Second International Symposia on Pharmacology of Natural Products Varadero, Cuba.

Traducción: Edgardo Fundora Diseño: Luciano O. Sánchez Núñez La revista Cubana de Plantas Medicinales es una revista arbitrada. Su arbitraje es a doble ciego, lo que hace anónimo el importante trabajo del que depende en gran medida la calidad del contenido de la publicación. Si bien el anonimato se aplica a que no se conoce quién revisa un trabajo determinado, sí puede informarse quiénes realizan esta tarea. Dar a conocer nuestros árbitros es la única forma de retribución, en este caso moral, que la revista puede ofrecer.
