research 11α-Hydroxyprogesterone, a potent 11β-hydroxysteroid dehydrogenase inhibitor, is metabolised by steroid-5α-reductase and cytochrome P450 17α-hydroxylase/17,20-lyase to produce C11α-derivatives of 21-deoxycortisol and 11-hydroxyandrostenedione in vitro
This study found that 11α-hydroxyprogesterone is a potent inhibitor of 11βHSD2 in vitro and may serve as a precursor to unique C11α-hydroxy steroids in prostate cancer tissue.
