Secondary metabolites from the fungus Chaetomium brasiliense

[摘要]：Two new depsidones, mollicellins I and J (1 and 2, resp.), and a new chromone, 2-(hydroxymethyl)-6-methylmethyleugenin (3), along with six known compounds, 4-9, were isolated from the ethyl acetate extract of a solid-state fermented culture of Chaetomium brasiliense. Their structures were elucidated based on spectroscopic analysis. Mollicellins I and H (5) exhibited significant growth inhibitory activity against human breast cancer (Bre04), human lung (Lu04), and human neuroma (N04) cell lines with GI(50) values between 2.5-8.6 mu g/ml.
