Furan Derivatives and Polyketides from the Fungus Irpex lacteus

Abstract

Eight new furan derivatives, irpexins A‒H (1‒8), two new polyketides, irpexins I and J (9 and 10), together with nine known compounds were isolated from the fermentation of Irpex lacteus. The structures and absolute configurations were elucidated on the basis of extensive spectroscopic methods and Mosher ester reaction. All compounds shows no cytotoxicity to human MCF-7 and Hela cancer cell lines at the concentration of 10 μM.
