Secondary Metabolites from Aspergillus fumigatus, an Endophytic Fungus from the Liverwort Heteroscyphus tener (STEPH.) SCHIFFN.

摘要

Three new metabolites, asperfumigatin (1), isochaetominine (10), and 8'-O-methylasterric acid (21), together with nineteen known compounds, were obtained from the culture of Aspergillus fumigatus, an endophytic fungus from the Chinese liverwort Heteroscyphus tener (STEPH.) SCHIFFN. Their structures were established by extensive analysis of the spectroscopic data. The absolute configurations of 1 and 10 were determined by analysis of their respective CD spectra. Cytotoxicity of these isolates against four human cancer cell lines was also determined.
