Androstenediol
From DrugPedia: A Wikipedia for Drug discovery
Androstenediol is a term used to refer to two different steroids with molecular weights of 290.44. They are 4-androstenediol (4-androstene-3beta,17beta-diol) and 5-androstenediol (5-androstene-3beta,17beta-diol).
4-Androstenediol is closer to testosterone structurally, and has androgenic effects.
5-Androstenediol is a direct metabolite of the most abundant steroid produced by the human adrenal cortex, dehydroepiandrosterone (DHEA). 5-Androstenediol is less androgenic than 4-androstenediol, and stimulates the immune system. When administered to rats in vivo, 5-androstenediol has approximately 1/70 the androgenicity of DHEA, 1/185 the androgenicity of androstenedione, and 1/475 the androgenicity of testosterone (Coffey, 1988). Because it induces production of white blood cells and platelets, 5-androstenediol is being developed as a radiation countermeasure by the Armed Forces Radiobiology Research Institute. Until 2007, it was being developed as a radiation countermeasure by Hollis-Eden Pharmaceuticals as Neumune (HE2100).
Androstenediol is on the list of substances banned by the Major League Baseball drug policy.

An intermediate in TESTOSTERONE biosynthesis, found in the TESTIS or the ADRENAL GLANDS. Androstenediol, derived from DEHYDROEPIANDROSTERONE by the reduction of the 17-keto group (17-HYDROXYSTEROID DEHYDROGENASES), is converted to TESTOSTERONE by the oxidation of the 3-beta hydroxyl group to a 3-keto group (3-HYDROXYSTEROID DEHYDROGENASES).
