Studies on the metabolites of Zygosporium masonii. Part II. Structures of zygosporins D, E, F, and G
Abstract
Zygosporins D, E, F, and G were isolated as minor metabolites of the fungus Zygosporium masonii and their cycloundeca[d]isoindole-1,11-dione structures were elucidated as (II), (IV), (III), and (IX), respectively. These compounds showed cytotoxicity against HeLa cells.
