Thus, this study aimed considering the UFRRJ potential by interdisciplinary and multiprofessional manner proposing the establishment of a Stricto Sensu Post Graduation course in phytotherapics and medicinal plants prioritizing the formation of human resources acting in whole productive chain from plant raw material harvested in the field and its processing to phytotherapic medicine industrial manufacture, as well as establishing criteria for the rational use of medicinal plants within the context of the Practices of Integrative and Complementary Actions of Health Ministry for health professionals besides complying with the National Policy Guidelines for Medicinal Plants and Phytotherapics. This qualitative, descriptive and exploratory research was carried out at Universidade Federal Rural do Rio de Janeiro (UFRRJ) in Serop?dica municipality-RJ. Data from January to July, 2016 were collected. Open unstructured interviews of participant observations by telephone and e-mail with professionals working in related areas were the instruments used. As a result, the UFRRJ, for its tradition in Agricultural Sciences teaching and research has presented in its Institutes, Departments, Disciplines, Laboratories and Research Groups all the potential and infrastructure for organizing and complying with the implementation of Phytotherapics and Medicinal Plants Stricto sensu Post Graduation course . / Em todas as ?pocas e culturas o homem aprendeu a tirar proveito dos recursos naturais locais, incluindo-se o uso de plantas medicinais. A fitoterapia apresenta grande potencial de desenvolvimento econ?mico e social, considerando-se n?o somente a diversidade vegetal que o Brasil possui, mas tamb?m porque o uso das plantas medicinais est? intimamente ligado ? cultura popular. Nos ?ltimos 25 anos, 77,8% dos agentes anticancer?genos testados e aprovados foram derivados de produtos naturais sendo inquestion?vel a contribui??o dos mesmos no desenvolvimento de novos f?rmacos (NOGUEIRA et al., 2010). Por outro lado, a Universidade tem por responsabilidade acompanhar a realidade de seu tempo e gerar conhecimento e massa cr?tica para transformar realidades, em benef?cio da sociedade, formando profissionais competentes, ?ticos e cidad?os comprometidos com o bem-estar da sociedade de hoje e do futuro. Nesse sentido, a cria??o de um curso de p?s-gradua??o stricto sensu nos moldes de Mestrado em Plantas Medicinais e Fitoter?picos para forma??o de profissionais capacitados para o processamento, a produ??o e controle de qualidade desde a mat?ria prima vegetal at? o produ??o de fitoter?picos torna-se fundamental para que os profissionais prescritores possam entender as diferen?as entre o conceito de fitoter?pico como medicamento e o uso de plantas medicinais segundo as pol?ticas do governo de Terapias Integrativas e Complementares, observando sempre a import?ncia racional do seu uso. Assim, este trabalho tem como objetivo geral levantar as potencialidades da UFRRJ para de forma interdisciplinar e multiprofissional, avaliar as condi??es para propor a cria??o de um curso de p?s-gradua??o stricto sensu em plantas medicinais e fitoter?picos priorizando a forma??o de recursos humanos para atuar em toda a cadeia produtiva que vai desde a mat?ria prima vegetal cultivada no campo, seu processamento, at? a produ??o industrial do medicamento fitoter?pico, bem como estabelecer crit?rios para o uso racional de plantas medicinais dentro do contexto das Pr?ticas de A??es Integrativas e Complementares do Minist?rio da Sa?de para os profissionais da sa?de al?m de atender as Diretrizes da Pol?tica Nacional de Plantas Medicinais e Fitoter?picos.

O transtorno de ansiedade generalizada tem aumentado de forma significativa, sendo o segundo transtorno mais prevalente em locais de assist?ncia ? sa?de p?blica. A depress?o ? considerada um transtorno psiqui?trico cr?nico e comum que afeta 350 milh?es de indiv?duos de todas as idades ao redor do mundo. Neste contexto as condutas de interven??o farmacol?gica que v?m sendo empregadas, embora eficazes, deixam a desejar, quando observados seus efeitos adversos. A Passiflora ? uma variedade comumente conhecida comercialmente, mas tamb?m ? usada na medicina tradicional brasileira. A Passiflora edulis exibe consider?vel variabilidade morfol?gica. Esta planta produz dois tipos de fruto: o roxo (P. edulis var. edulis) e o amarelo (P. edulis var. flavicarpa). O presente estudo investigou os efeitos centrais do extrato aquoso das folhas de duas variedades da esp?cie Passiflora edulis em testes comportamentais utilizados para avaliar comportamentos relacionados ? ansiedade e depress?o, bem como investigou o potencial efeito do tipo antidepressivo das subfra??es da Passiflora edulis var. edulis e os mecanismos neurofarmacol?gicos respons?veis por essa a??o. Para a realiza??o desse estudo foram utilizados camundongos Swiss machos (2 meses de idade, pesando 30-35 g). Os animais receberam o extrato aquoso das folhas das duas esp?cies de Passiflora: Passiflora edulis Sims var. edulis (PEE - 100, 300, 1000 mg/Kg) e subfra??es AcOet, BuOH e residual (25, 50, 75, 100 mg/Kg), e a P. edulis var. flavicarpa (PEF - 30, 100, 300, 1000 mg/Kg) ou solu??o salina, por gavagem, 60 minutos antes dos testes do labirinto em cruz elevado (LCE), teste de campo aberto (TCA), teste de nata??o for?ada (TNF) e teste de seda??o induzido por tiopental. Para investigar o mecanismo de a??o da atividade do tipo antidepressiva das subfra??es foram utilizadas as seguintes drogas: PCPA (inibidor da s?ntese de 5-HT), AMPT (inibidor da s?ntese de catecolaminas), DSP-4 (neurotoxina noradren?rgica) e Sulpiride (antagonista seletivo de receptor dopamin?rgico D2). Foram utilizados como controle positivo padr?o, a fluoxetina e a nortriptilina. Os resultados do perfil fitoqu?mico demonstram caracter?sticas bem distintas para o extrato aquoso das variedades de P. edulis ?flavicarpa? e ?edulis?. Os extratos aquosos de ambas as variedades de P. edulis compartilham atividade do tipo ansiol?tica (PEE 300 mg/Kg; PEF 300 e 1000 mg/Kg) e antidepressiva (PEE 300 mg/Kg; PEF 1000 mg/Kg), enquanto o efeito hipolocomotor/sedativo s? foi visto para a PEE (1000 mg/Kg). Ambas subfra??es AcOet e BuOH do extrato aquoso da PEE apresentaram atividade do tipo antidepressiva na dose de 50 mg/Kg no TNF. Os dados sugerem que o efeito do tipo antidepressivo das subfra??es da P. edulis envolve a neurotransmiss?o serotonin?rgica e catecolamin?rgica, principalmente dopamin?rgica, haja visto que o pr?-tratamento com DSP-4 n?o afetou a a??o antidepressiva das subfra??es, enquanto que mostrou ser dependente da ativa??o de receptores dopamin?rgicos D2. / The medicinal plants constitute a rich source of biologically active compounds used for the treatment of many psychiatric disorders, such as anxiety disorders and depression. Generalized anxiety disorder has increased significantly, being the second most prevalent disorder in care facilities to public health. Depression is considered a chronic and common psychiatric disorder that affects 350 million people of all ages around the world. In this context, the pharmacological intervention conduits have been employed, effective, although leave to be desired when observed adverse effects. The genus Passiflora is commonly commercially known by its fruit, but is also widely used in traditional Brazilian medicine. Passiflora edulis displays considerable morphological variability. This plant produces two types of fruit: Purple (Passiflora edulis Sims fo. edulis) and yellow (Passiflora edulis fo. flavicarpa Degener). This study investigated the central effects of aqueous extract of the leaves of the two varieties of the species Passiflora edulis in tests used to assess behavior related to anxiety and depression, as well as investigating the potential effect of the antidepressant-like fractions of edulis fo. edulis and neuropharmacological mechanisms responsible for this action. To conduct this study used male Swiss mice (2 months old, weighing 30-35 g). The animals received the aqueous extract of the leaves of the two species of Passiflora: edulis fo. edulis (100, 300, 1000 mg / kg) and fractions ethyl acetate, butanol and aqueous waste (25, 50, 75, 100 mg / kg) and edulis fo. flavicarpa (30, 100, 300, 1000 mg / kg) or saline by gavage 60 minutes prior to the maze tests at high cross the open field test, test forced swim test and sedation induced by thiopental. To investigate the mechanism of action of the activity of antidepressant type of fractions the following drugs were used: PCPA (inhibitor of 5-HT synthesis) AMPT (inhibitor of catecholamine synthesis), DSP-4 (noradrenergic neurotoxin) and Sulpiride (antagonist selective dopamine D2 receptor). They were used as a standard positive control, fluoxetine and nortriptyline. The results of the phytochemical profile show very different characteristics to the aqueous extract of the varieties of Passiflora edulis "flavicarpa" and "edulis". The aqueous extracts of both varieties of Passiflora edulis share anxiolytic activity type (edulis fo. edulis 300 mg/kg; edulis fo. flavicarpa 300 and 1000 mg/kg) and antidepressant (edulis fo. edulis 300 mg/kg; edulis fo flavicarpa 1000 mg/kg), while the effect hipolocomotor/sedative was only seen for edulis fo. edulis (1000 mg/kg). Both fractions ethyl acetate, butanol aqueous extract edulis fo. edulis showed activity type antidepressant at a dose of 50 mg/kg in the forced swim test. The data suggest that the effect of antidepressant-like fractions edulis fo. edulis involves catecholaminergic and serotonergic neurotransmission, particularly dopaminergic, there is seen that pre-treatment DSP-4 is not affected antidepressant action of fractions as was dependent activation of dopamine D2 receptors.

No primeiro estudo, as estabilidades dos sistemas ER?-OHT (Receptor ? de Estr?geno-Hidroxitamoxifeno), ER?-RAL (Receptor ? de Estr?geno-Raloxifeno) e Integrina ?v?3-Cilengitide foram determinadas em termos energ?ticos a partir da t?cnica de fracionamento molecular com capuzes conjugados (MFCC) e no escopo da teoria do funcional da densidade (DFT) seguindo o esquema GGA-PBE-Grimme para calcular a intera??o energias dos sistemas estudados. No primeiro estudo, foi poss?vel predizer a relev?ncia individual dos amino?cidos Glu, Asp, Arg, Lys no sistema com o Tamoxifeno e Glu, Asp e Lys com o Raloxifeno. Para isso ser poss?vel, as for?as de atra??o e repuls?o dos res?duos que comp?em os sistemas foram calculadas. Cada um desses res?duos apresentou uma energia de intera??o que variou dependendo da natureza qu?mica da sua cadeia lateral, do ambiente de microsolvata??o que o envolve e dos contatos intermoleculares que estabelece. O estudo pioneiro da estabilidade conformacional em termos energ?ticos de uma regi?o livre de amino?cidos incitar? pesquisas centradas no desenvolvimento e s?ntese de novos antagonistas utilizados no tratamento de diversas patologias comuns na popula??o geral. No segundo estudo, foram determinadas as propriedades energ?ticas do sistema Integrina ?V?3-Cilengitide, cuja estrutura cristalogr?fica apresenta c?tions Mn+2. Observou-se a import?ncias dos amino?cidos Ser, Asp, Leu, Arg, Lys, Ala e Pro na intera?ao da integrina com o fragmento RGD (R: arginina; G: glicina; D: ?cido asp?rtico) do cilengitide. A import?ncia da integrina com o fragmento RGD no mecanismo de ades?o de diversas c?lulas envolvidas nas doen?as cancer?genas e tamb?m na implanta??o embrion?ria permitir? o desenvolvimento de novas terapias impactantes na sobrevida de pacientes portadores de diversas neoplasias e na reprodu??o humana. / This thesis deals with two researches with different conceptual nature in the field of molecular modeling based on similar theoretical principles of quantum physics and computational chemistry. In the first study the stabilities of ER?-OHT (Receptor ? Estrogen co-crystalyzed with Hydroxytamoxifen), ER?-RAL (?-Estrogen Receptor co-crystalyzed with Raloxifene) and integrin ?v?3 co-crystalyzed with cilengitide systems were determined in terms of energy from the Molecular Fractionation Technique Caps Conjugates (MFCC), and the scope of the Density Functional Theory (DFT) following GGA-PBE-Grimme scheme for calculating the interaction energy of the systems studied. In the first study, it was possible to predict the relevance of individual amino acids Glu, Asp, Arg, Lys in the system with Tamoxifen and Glu, Asp and Lys in Raloxifene system. For this to be possible, the attraction and repulsion forces of the residues that comprise the systems were calculated. Each of these residues had an energy of interaction that varied depending on the chemical nature of the side chain, the microsolvation environment that surrounds and intermolecular contacts establishing. The pioneer study of conformational stability in terms of energy of free amino acid region will encourage research focusing on the development and synthesis of new antagonists used in the treatment of several common diseases in the general population. In the second study, we determined the energetic properties of Integrin ?V?3-cilengitide system, whose crystallographic structure has Mn+2 cations. It was noted the importance of amino acids Ser, Asp, Leu, Arg, Lys, Ala and Pro in integrin interaction with the RGD fragment (R: arginine; G: glycine; D: aspartic acid) of cilengitide. The importance of integrin with the RGD fragment in the adhesion mechanism of various cells involved in cancers and in embryo implantation allows the development of new therapies impacting on survival of patients with various forms of neoplasms and in human reproduction.
