用途
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.
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.
製法・合成法
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).
