エピアンドロステロン 化學(xué)特性,用途語(yǔ),生産方法
説明
Epiandrosterone is a steroid hormone with weak androgenic activity, derived from 5 α-androstane. It is a dehydroepiandrosterone metabolite and an androgen. It is a precursor of testosterone and estradiol with hypolipidemic and anabolic activities.
化學(xué)的特性
white to off-white crystalline powder. Musky odor when heated.
使用
Epiandrosterone is used for weight loss, to improve athletic performance, to reduce sexual problems, and for many other uses, but there is no good scientific evidence to support its use. Epiandrosterone might also be unsafe.
Epiandrosterone is a steroid hormone that is present in normal human urine as a minor constituent , it is a less active 3β-isomer of the androgen Androsterone (A635535). Controlled Substance.
定義
ChEBI: Epiandrosterone is a 3beta-hydroxy steroid that is (5alpha)-androstane substituted by a beta-hydroxy group at position 3 and an oxo group at position 17. It has a role as an androgen and a human metabolite. It is a 17-oxo steroid, a 3beta-hydroxy steroid and an androstanoid. It derives from a 5alpha-androstane.
純化方法
Purify epi-androsterone via the acetate, hydrolyse this and recrystallise it from CHCl3/hexane or aqueous EtOH. The acetate [1239-31-2] is purified by chromatography and when crystallised from pet ether has m 103-104o, []D +68.5o (c 1, CHCl3). The oxime has m 194-196o (from MeOH), []D +17.5o (c 6.2, CHCl3). The racemic ketone is sublimed at 130o/high vacuum and after two crystallisations from methylcyclohexane it gives prisms with m 161-162o (which changed crystal form at 140-145o).
