Abstract

Seven cadinane sesquiterpenoids, named boreovibrins A–G 1 –7 , three dihydrobenzofurans 8 –10 , and two lactones 11 and 12 , together with one known compound 13 , were isolated from cultures of the basidiomycete Boreostereum vibrans. The new structures were elucidated by means of spectroscopic methods. Compounds 5 , 6 , and 11 showed weak inhibitory activities against isozymes of 11β-hydroxysteroid dehydrogenases 11β-HSD.
