Ten polyketides, including three new chromone derivatives (1, 2 and 5), a pair of new epimer mixtures (3 and 4), a new azaphilone analogue (6) and four known compounds (7~10) were isolated from the deep-sea-derived fungus Diaporthe phaseolorumFS459. Their structures were elucidated by extensive spectroscopic analysis, while the absolute configurations were established by comparison of experimental and quantum chemical calculated electronic circular dichroism (ECD) spectra. Compounds 1~4 possessed a rare 2?,3?-dimethyl-dioxolane moiety. Thein vitro cytotoxicity, antibacterial activities and NO production inhibitory effects of compounds 1~10 were evaluated.

Key words: polyketides, deep-sea-derived fungus, Diaporthe phaseolorum, cytotoxicity
