5β-双氢睾酮

化合物

5β-双氢睾酮(英語:5β-Dihydrotestosterone,简称为5β-DHT,也称为5β-雄甾烷-17β-醇-3-酮,5β-androstan-17β-ol-3-one,或本胆烷-17β-醇-3-酮,etiocholan-17β-ol-3-one)是一种本胆烷类(5β-雄烷甾体物质,和睾酮的无雄激素活性的代谢产物,由肝脏骨髓中的5β还原酶生成[1][2],同时也是生成3α-本胆烷二醇3β-本胆烷二醇(分别由3α-3β-羟基类固醇脱氢酶催化)的底物,之后再分别转化为本胆烷醇酮表本胆烷醇酮(由17β-羟基类固醇脱氢酶催化)[3][4]。和其表观异构体5α-双氢睾酮(5α-DHT或简称DHT)不同,5β-DHT只有非常弱的结合雄激素受体的能力[1]。作为主要的睾酮代谢产物,5β-DHT的A环和B环形之间的“顺式”结构使两个环在空间上形成了一个角度,故而缺乏了雄激素活性[5]。5β-DHT和5α-DHT的另一个不同点是,5β-DHT还缺乏神经甾体活性[6][7]但其代谢产物,本胆烷醇酮却有神经甾体活性[8][9]
