  • 3β-HSD is also known as delta Δ5-4-isomerase, which catalyzes the oxidative conversion of Δ5-3β-hydroxysteroids to the Δ4-3-keto configuration and is, therefore, essential for the biosynthesis of all classes of hormonal steroids, namely progesterone, glucocorticoids, mineralocorticoids, androgens, and estrogens.

  • 3β-Hydroxysteroid dehydrogenase (3β-HSD) inhibitors such as amphenone B, azastene, cyanoketone, epostane, mitotane, and trilostane inhibit the conversion of Δ5-3β-hydroxysteroids into Δ4-3-ketosteroids and thereby inhibit the production of most of the steroid hormones. (wikipedia.org)
