Abstract

Three new metabolites, vibralactones D-F (1-3) were isolated from cultures of the basidiomycete Boreostereum vibrans. The relative configuration of 1 was established on the basis of X-ray diffraction analysis, while the absolute configurations of 1-3 were assigned using a modified Mosher's method. Compound 1 showed weak inhibitory activities against isozymes of 11beta-hydroxysteroid dehydrogenases (HSD) with IC(50) values of 85.7 microM (human HSD1), 295.2 microM (mouse HSD1), and 87.1 microM (human HSD2).
