A new azaphilone, chaephilone E, eight azaphilone derivatives, and three chaetoglobosins were isolated from endophytic fungi Chaetomium globosum. The structures of the compounds were elucidated by 1D and 2D NMR as well as HR‐ESI‐MS data, and the absolute configuration of chaephilone E was established on the basis of electronic circular dichroism and NOESY spectrum. The activity of chaephilone E was evaluated via the cytotoxic assay (human hepatoma cell lines HepG‐2) and brine shrimp (Artemia salina) bioassay. 相似文献

Two new azaphilone compounds, daldinins G ( 1 ) and H ( 2 ), together with nine known compounds daldinin D ( 3 ), sargassopenilline B ( 4 ), austalide V ( 5 ), austalide K ( 6 ), austalide P ( 7 ), austalide P acid ( 8 ), austalide H ( 9 ), 13-O-deacetyaustalide I ( 10 ), and 17-O-demethylaustalide B ( 11 ), were isolated from the soft coral-derived fungus Penicillium glabrum glmu003. The new structures of 1 and 2 were elucidated on the basis of 1D and 2D NMR, mass spectra, and electronic circular dichroism (ECD) data analysis. Compound 5 showed weak inhibitory activity against pancreatic lipase (PL) with IC50 value of 23.9 μg/mL. 相似文献
