Abstract

Microbial transformation of adrenosterone (1) by suspended-cell cultures of the filamentous fungus Cunninghamella elegans resulted in the production of five metabolites 2–6, which were identified as 9α-hydroxyadrenosterone (2), 11-ketotestosterone (3), 6β-hydroxyadrenosterone (4), 9α-hydroxy-11-ketotestosterone (5), and 6β-hydroxy-11-ketotestosterone (6). Structures of new metabolites 2, 5, and 6 were established by single-crystal X-ray diffraction analysis.
