title: Androsterone 3beta-substituted derivatives as inhibitors of type 3 17beta-hydroxysteroid dehydrogenase.
abstract: Androsterone derivatives substituted at position 3 were synthesized starting from dihydrotestosterone in a short sequence of reactions. They proved to be potent inhibitors (IC50 = 57-147 nM) of type 3 17beta-hydroxysteroid dehydrogenase, a key enzyme of steroidogenesis, which catalyzes the transformation of androstenedione to steroid active androgen testosterone.
