Gestadienol acetate

Gestadienol acetate (developmental code name CIBA-31458-Ba or CIBA-31458) an orally active progestin which was described in the literature in 1967 and was never marketed.[3][1][2][4][5] It has no androgenic or estrogenic effects.[6] The effects of gestadienol acetate on the endometrium and its general pharmacology were studied in a clinical trial in women.[2][5] It has also been studied in a clinical trial for benign prostatic hyperplasia in men, but was ineffective.[6]

Gestadienol acetate, also known as norhydroxy-δ6-progesterone acetate, 6-dehydro-17α-hydroxy-19-norprogesterone 17α-acetate, or 17α-hydroxy-19-norpregn-4,6-diene-3,20-dione 17α-acetate, is a synthetic norpregnane steroid and a derivative of progesterone.[3] It is specifically a combined derivative of 17α-hydroxyprogesterone and 19-norprogesterone, or of gestronol (17α-hydroxy-19-norprogesterone), with an acetate ester at the C17α position and a double bond between the C6 and C7 positions.[3] Gestadienol acetate is the C17α acetate ester of gestadienol.[3] Analogues of gestadienol acetate include algestone acetophenide (dihydroxyprogesterone acetophenide), demegestone, gestonorone caproate (norhydroxyprogesterone caproate), hydroxyprogesterone acetate, hydroxyprogesterone caproate, nomegestrol acetate, norgestomet, and segesterone acetate (nestorone).[3]
