elegans and Fusarium lini yielded 11α,17α- dihydroxypregn-4-ene-3,20-dione (9), and 17α-hydroxypregna-1,4-diene-3,20-dione (10). The structures of the metabolites 3 - 10 were deduced on the basis of spectroscopic methods. Compound 3 was identified as a new metabolite, which exhibited a promising inhibitory activity against the α-glucosidase enzyme.
11α-羟基孕酮 (1) 与 Cunninghamella elegans、Gibberella fujikuroi、Fusarium lini 和白色念珠菌的微生物转化产生 11α,15α,16α-trihydroxypregn-4-ene-3,20-dione (3), 11α-hydroxy pregnane-3,20-dione (4), 6β,11α-dihydroxypregn-4-ene-3,20-dione (5), 11α-hydroxypregna-1,4-diene-3,20-dione (6), 11α ,17β-dihydroxyandrost-4-en-3-one (7) 和 11α,15α-dihydroxypregn-4-ene-3,20-dione (8)。另一方面,17α-羟基孕酮 (2) 与 Cunninghamella elegans 和 Fusarium
