Abstract

Three novel cytotoxic substances named prenylterphenyllin (1), 4''-deoxyprenylterphenyllin (2), and 4''-deoxyisoterprenin (3) were isolated from a cultured marine-derived fungus of Aspergillus candidus IF10 together with 4''-deoxyterprenin (4). Their chemical structures were elucidated on the basis of 2D NMR analysis. These compounds 1 approximately 4 showed cytotoxic activity against human epidermoid carcinoma KB cells (KB3-1) with IC(50) of 8.5, 3.0, 2.5, and 4.5 microg/ml, respectively.
