Isoprenylated chromone derivatives from the plant endophytic fungus Pestalotiopsis fici.
Pestaloficiols F-L (1-7), new isoprenylated chromone derivatives including one heterodimer (7), have been isolated from a scale-up fermentation extract of the plant endophytic fungus Pestalotiopsis fici. The structures of these compounds were elucidated primarily by NMR and MS methods. The absolute configurations of 1 and 4 were assigned using the modified Mosher method. Compounds 1-3, 5, and 6 displayed inhibitory effects on HIV-1 replication in C8166 cells, whereas 4-7 showed cytotoxic activity against the human tumor cell lines HeLa and MCF7.
