| Abstract: | Objective To study the chemical constituents in the cultured filaments of an antitumor actinomycete strain (N2010-37). Methods Compounds were isolated and purified by chromatographic techniques and recrystallization, and the structures were identified by spectral methods together with physicochemical analysis. The antitumor effects of these compounds were tested in vitro by MTT method. Results Three compounds were identified including two anthrones and one novel macrolide. They were (3S, 4R, 7R, 8R, 9S)-3, 8-dihydroxy-4, 7, 9-trimethyl-2, 6-cyclononanediiolacetone (1), 2-hydroxy-1-methoxy-3-methylanthraquinone (2), and 1, 6, 8-thihydroxy-3-methylanthraquinone (3). Conclusion Compound 1 is a new compound, and compounds 1 and 3 show the favorable cytotoxic activity against human chronic granulocytic leukemia cell line K562 strain by MTT method in vitro. |
