ABSTRACT
Chemical investigation of the fungus Trichoderma asperellum SCNU-F0048 led to the discovery of two new steroids, ergosta-4,6,8 (14),22-tetraen-3-(3'-methyl-4'-hydroxyl-γ-butenolide) (1) and camphosterol B (2), as well as two known compounds, i.e. stigmasta-4,6,8(14),22-tetraen-3-one (3) and 4-hydroxy-17- methylincisterol (4). Their structures were elucidated by extensive nuclear mangnetic resonance, spectrum analysis and single crystal X-ray diffraction analysis. Bioassay disclosed that compound 1 showed strong cytotoxicity to a panel of tumor cell lines. Moreover, compounds 1 and 2 showed excellent antifungal activity against Penicillium italicum with IC50 values of 0.016 and 0.022 µM, respectively.
