Epostane (INN, USAN, BAN) (developmental code name WIN-32729) is an inhibitor of 3β-hydroxysteroid dehydrogenase (3β-HSD) that was developed as a contraceptive, abortifacient, and oxytocic drug but was never marketed.[1][2][3] By inhibiting 3β-HSD, epostane blocks the biosynthesis of progesterone from pregnenolone (and also the conversion of dehydroepiandrosterone to androstenedione), thereby functioning as an antiprogestogen and terminating pregnancy.[1] The drug was trialed and in a study was found to be slightly more effective at inducing abortion relative to mifepristone.[4]
