Abstract

Eight new phenethoxy derivatives, trichoasperellins A-H (1-8), were isolated from the endophytic fungus Trichoderma asperellum G10 isolated from the medicinal plant Areca catechu L. The structures of these compounds were elucidated from spectroscopic data, J-based configurational analysis, and Mosher's methods. Compounds 1-4 and 6-8 bear one or two multioxidized C7 moieties with the same carbon skeleton. The carbon skeletons of compounds 6-8 are new, all containing three moieties connected via two acetal carbons similar to those of disaccharide glycosides. Compound 4 inhibited nitric oxide production with an IC50 value of 48.3 μM, comparable to that of the positive control indomethacin (IC50, 42.3 μM).
