Five new polyketides from the basidiomycete Craterellus odoratus


ABSTRACT: Five new polyketides, craterellones A–E (1–5), were isolated from cultures of basidiomycete Craterellus odoratus, together with five known compounds (6–10). Structures of 1–5 were elucidated on the basis of extensive spectroscopic analysis. All compounds were evaluated for their inhibitory activities against one isozyme of 11β-hydroxysteroid dehydrogenase (11β-HSD1) and cytotoxic activities on five tumor cell lines. Compound 10 exhibited significant cytotoxicity against HL-60, SMMC-7721, A-549, MCF-7, and SW-480, with IC50 values of 0.50, 0.69, 0.64, 1.10, 0.54 µM, respectively.
