Microbial transformation of contraceptive drug etonogestrel into new metabolites with Cunninghamella blakesleeana and Cunninghamella echinulata
文摘

Five metabolites of contraceptive drug etonogestrel (1) were synthesized through biotransformation by fungi.

Biotransformation of 1Cunninghamella blakesleeana yielded metabolites 2–6.

Biotransformation of 1Cunninghamella echinulata yielded metabolites 2, 4, and 6.

6β-Hydroxy-etonogestrel (5) was found to be active against β-glucuronidase enzyme.
