Produtos naturais: atualidade, desafios e perspectivas

Abstract: INTRODUÇÃOO Brasil, com a grandeza de seu litoral, de sua flora e, sendo o detentor da maior floresta equatorial e tropical úmida do planeta, não pode abdicar de sua vocação para os produtos naturais. A Quí-mica de Produtos Naturais (QPN) é, dentro da Química brasileira, a área mais antiga e a que, talvez ainda hoje, congregue o maior núme-ro de pesquisadores.Para facilitar a compreensão do texto e melhor situá-lo no contexto da QPN brasileira, julgou-se apropriado descrever alguns marcos históricos na evoluçã… Show more

“…Successive chromatography procedures of the CH 2 Cl 2 :MeOH (3:7) extract of L. theobromae cultivated in rice provided ergosterol (1). When cultivated in Czapeck broth, this fungus provided isocoumarin 4-hydroxymelein (2) and a new eremophilane-type sesquiterpene (3) after column chromatography of the EtOAc and n-BuOH fractions obtained by partition of the liquid medium ( Figure 1).…”

“…Because of the short life cycle and easy adaptability to external media, fungi can be manipulated for the production of secondary metabolites of biological interest. 1 About 1500 secondary metabolites from fungi were reported in the literature from 1993 to 2001, and more than 50% of these compounds showed antibacterial, antifungal and antitumoral activities. 2 Chemical investigation of phytopatogen fungi, especially those associated with serious agricultural problems, was recently begun.…”

“…Then, the 1 H and 13 C NMR data were compared with the literature allowing identify them as uracil (2), uridin (3) and p-hydroxybenzoic acid (4) (Marinho et al 2007). The compounds 2 and 3 are nitrogenous bases and show antiviral activity (Pinto et al 2002).…”
