Metabolite Identification
Common Name5-Androstenediol
Description5-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 (Wikipedia ). Because it induces production of white blood cells and platelets, 5-androstenediol is being developed as a radiation countermeasure as Neumune (HE2100). An intermediate in testosterone biosynthesis, found in the testis or the adrenal glands. 5-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-fydroxysteroid dehydrogenase).
