  Exploitation of Cholane Scaffold for the Discovery of Potent and Selective Farnesoid X Receptor (FXR) and G-Protein Coupled Bile Acid Receptor 1 (GP-BAR1) Ligands

  摘要：

  Nuclear and G-protein coupled receptors are considered major targets for drug discovery. FXR and GP-BAR1, two bile acid-activated receptors, have gained increasing consideration as druggable receptors. Because endogenous bile acids often target both receptor families, the development of selective ligands has been proven difficult, exposing patients to side effects linked to an unwanted activation of one of the two receptors. In the present study, we describe a novel library of semisynthetic bile acid derivatives obtained by modifications on the cholane scaffold. The pharmacological characterization of this library led to the discovery of 7a-hydroxy-5 beta-cholan-24-sulfate (7), 6 beta-ethyl-3a,7 beta-dihydroxy-5 beta-cholan-24-ol (EUDCOH, 26), and 6a-ethyl-3a, 7a-dihydroxy-24-nor-5 beta-cholan-23-ol (NorECDCOH, 30) as novel ligands for FXR and GP-BAR1 that might hold utility in the treatment of FXR and GP-BAR1 mediated disorders.

  A highly selective hydrogenation of 3-keto in steroids to 3-hydroxyl steroids catalyzed by hydroxysteroid dehydrogenases (HSDHs) was demonstrated. The Ct3α-HSDH-catalyzed hydrogenation generated 3α-hydroxyl steroids as the main enantiopure isomers in high yields, while the Ss3β-HSDH catalytic system afforded 3β-hydroxyl steroids in excellent yields. In both catalytic systems, the hydrogenation proceeded

  证明了在羟基类固醇脱氢酶 (HSDH) 的催化下，类固醇中的 3-酮基可以高度选择性地氢化为 3-羟基类固醇。 Ct3α-HSDH催化的氢化反应以高产率产生了作为主要对映体纯异构体的3α-羟基类固醇，而Ss3β-HSDH催化体系则以优异的产率产生了3β-羟基类固醇。在两种催化体系中，氢化反应在 3-酮基上进行区域选择性，7-、11-、17-和 20-酮基几乎未反应，并且在 C=C 键和酯基未受攻击的情况下进行化学选择性氢化。我们的HSDH促进的氢化反应具有区域选择性、化学选择性和对映选择性高、收率好、条件温和、底物范围广、适合克级合成等优点。值得注意的是，通过我们的氢化方法，可以轻松、高产地获得脱氢表雄酮、布烯醇酮和阿法沙酮等生物活性分子。
