摘要: To study the cytotoxic constituents from marine actinomycete Streptomyces sp. (124092) of rhizosphere soil of mangrove plant Heritiera littoralis, five compounds were isolated by column chromatography from the fermentation broth of marine actinomycete Streptomyces sp. (124092 Their structures were elucidated as p-tolyl 3-aminopropanoate(1) 6-amino-3-(4-hydroxybenzyl) -1, 4-diazonane-2,5-dione(2), n-butyl mannoside(3), daidzein(4), and indole-g-carboxylic acid(5), by MS, NMR, (1)H-(1)H COSY, HMQC, and HMBC spectra. Among them, compounds I and 2 are new compounds. Cytotoxic bioassay results show that compounds 1-4 possess inhibitory effects on human hepatoma SMMC-7721 cell line in vitro.
