11α-Hydroxyprogesterone (11α-OHP), or 11α-hydroxypregn-4-ene-3,20-dione is an endogenous steroid and metabolite of progesterone.[1][2][3] It is a weak antiandrogen, and is devoid of androgenic, estrogenic, and progestogenic activity.[4][5][6]

11α-OHP was investigated as a topical antiandrogen for the treatment of androgen-dependent skin conditions in the early 1950s, and was found to produce some benefit.[7] In 1995, 11α-OHP, along with its epimer 11β-hydroxyprogesterone, was identified as a very potent competitive inhibitor of both isoforms (1 and 2) of 11β-hydroxysteroid dehydrogenase (11β-HSD).[2][3] It is notably not metabolized by 11β-HSD2.[8]

11α-OHP is a more potent inhibitor of 11β-HSD than enoxolone (glycyrrhetinic acid) or carbenoxolone in vitro (IC50 = 0.9 nM; IC50 = 5 nM in transfected cells).[8][9][10] The compound has been found to be highly active in conferring mineralocorticoid sodium-retaining activity of corticosterone in vivo in rat bioassays and in increasing blood pressure, effects that it mediates by preventing the 11β-HSD-mediated inactivation of endogenous corticosteroids.[2][3]

11α-OHP is used as a precursor in chemical syntheses of cortisone and hydrocortisone.[11][12][13]
