dc.description.abstract | Fracionamento cromatográfico do extrato antileishmania obtido da fermentação do fungo endofítico Penicillium citrinum, isolado de folhas de Ageratum myriadenia, rendeu três alcalóides de dicetopiperazina; ciclo(L-Pro-L-Leu) (1), ciclo-(L-Pro-L-Phe) (2) e triprostatina B (3). O estruturas desses compostos foram estabelecidas com base em métodos espectroscópicos e comparação com a literatura. Os compostos 1 e 2 foram ativos contra ambas as formas de Leishmania (Leishmania) amazonensis e amastigotas intracelulares de L. (Leishmania) infantum com aproximadamente 50% de inibição do crescimento do parasita a 100 μM. Nenhum dos compostos foi considerado tóxico contra a linha celular de monócitos de leucemia humana (THP-1) a 100 μM. É o primeiro relato sobre isolamento dessas dicetopiperazinas de P. citrinum e seu potencial antileishmania contra L. (L.) infantum. | pt_BR |
dc.description.resumo | Chromatographic fractionation of the antileishmanial extract obtained from fermentation of the endophytic fungus Penicillium citrinum, isolated from leaves of Ageratum myriadenia, yielded three diketopiperazine alkaloids; cyclo(L-Pro-L-Leu) (1), cyclo-(L-Pro-L-Phe) (2) and tryprostatin B (3). The structures of these compounds were established on the basis of spectroscopic methods and comparison with the literature. Compounds 1 and 2 were active against both amastigote-like forms of Leishmania (Leishmania) amazonensis and intracelular amastigotes of L. (Leishmania) infantum with approximately 50% of parasite growth inhibition at 100 μM. None of the compounds were considered toxic against human leukemia monocyte cell line (THP-1) at 100 μM. It is the first report about isolation of these diketopiperazines from P. citrinum and their antileishmanial potential against L. (L.) infantum. | pt_BR |
