Abstract
Fermentation of mesterolone (1) with Cunninghamella blakesleeana yielded four new metabolites, 1α-methyl-1β,11β,17β-trihydroxy-5α-androstan-3-one (2), 1α-methyl-7α,11β,17β-trihydroxy-5α-androstan-3-one (3), 1α-methyl-1β,6α,17β-trihydroxy-5α-androstan-3-one (4) and 1α-methyl-1β,11α,17β-trihydroxy-5α-androstan-3-one (5), along with three known metabolites, 1α-methyl-11α,17β-dihydroxy-5α-androstan-3-one (6), 1α-methyl-6α,17β-dihydroxy-5α-androstan-3-one (7) and 1α-methyl-7α,17β-dihydroxy-5α-androstan-3-one (8). Biotransformation of 1 with Macrophomina phaseolina also yielded a new metabolite, 1α-methyl, 17β-hydroxy-5α-androstan-3,6-dione (9). The isolated metabolites were subjected to various in vitro biological assays, such as anti-cancer, inhibition of α-glucosidase, and phosphodiesterase-5 enzymes and oxidative brust. However, no significant results were observed. This is the first report of biotransformation of 1 with C. blakesleeana and M. phaseolina.Entities:
