Penidioxolanes A and B, 1,3-Dioxolane Containing Azaphilone Derivatives from Marine-derived Penicillium sp. KCB12C078
2015
Two new azaphilone derivatives containing 1,3-dioxolane moiety, penidioxolanes A (1) and B (2), were isolated from marine-derived fungus Penicillium sp. KCB12C078, together with four known compounds (36) by chemical investigation. Compounds 1 6 were isolated by combination of silica gel, ODS column chromatography and preparative HPLC. Their structures were determined by analysis of spectroscopic data including 1D-, 2D-NMR, and MS techniques. The isolates were evaluated against cancer cell growth inhibition effects and antimicrobial activity.
