摘要
Five new prenylated indole alkaloids, 17-hydroxynotoamide D (1), 17-O-ethylnotoamide M (2), 10-O-acetylsclerotiamide (3), 10-O-ethylsclerotiamide (4), and 10-O-ethylnotoamide R (5) were isolated from a co-culture of marine-derived fungi Aspergillus sulphureus KMM 4640 and Isaria felina KMM 4639. The structures of 1-5 were determined by detailed analysis of spectroscopic data and by comparison with related known compounds. The absolute configurations of 1-5 were determined by time-dependent density functional theory (TD-DFT) calculations of ECD spectra. Compound 2 is able to inhibit the colony formation of human prostate cancer cells 22Rv1 at non-cytotoxic concentration of 10 mu M.
