CAS 53-41-8 Androsterone Product Name: AndrosteroneCAS No.: 53-41-8EINECS:200-173-4Molecular Formula: C19H30O2Molecular Weight: 290.44Assay: 99% Melting Point: 181-184 centigradeAppearance: White or white crystalline powder Usage:Pharmaceutical Androsterone, or 3-hydroxy-5-androstan-17-one, is an endogenous steroid hormone, neurosteroid, and putative pheromone. It is a weak androgen with a potency that is approximately 17th that of testosterone.In addition, it can be converted to dihydrotestosterone (DHT) from 3-hydroxysteroid dehydrogenase and 17-hydroxysteroid dehydrogenase, bypassing conventional intermediates such as androstenedione and testosterone, and as such, can be considered to be a metabolic intermediate in its own right.Androsterone is also known to be an inhibitory androstane neurosteroid, acting as a positive allosteric modulator of the GABAA receptor, and possesses anticonvulsant effects.The unnatural enantiomer of androsterone is more potent as a positive allosteric modulator of GABAA receptors and as an anticonvulsant than the natural form. Androsterone's 3-isomer is epiandrosterone, and its 5-epimer is etiocholanolone.
