  Investigation on bile acid receptor regulators. Discovery of cholanoic acid derivatives with dual G-protein coupled bile acid receptor 1 (GPBAR1) antagonistic and farnesoid X receptor (FXR) modulatory activity

  摘要：

  Bile acids, the end products of cholesterol metabolism, activate multiple mechanisms through the interaction with membrane G-protein coupled receptors including the bile acid receptor GPBAR1 and nuclear receptors such as the bile acid sensor, farnesoid X receptor (FXR). Even if dual FXR/GPBAR1 agonists are largely considered a novel opportunity in the treatment of several liver and metabolic diseases, selective targeting of one of these receptors represents an attractive therapeutic approach for a wide range of disorders in which dual modulation is associated to severe side effects. In the present study we have investigated around the structure of LCA generating a small library of cholane derivatives, endowed with dual FXR agonism/GPBAR1 antagonism. To the best of our knowledge, this is the first report of bile acid derivatives able to antagonize GPBAR1. (C) 2015 Elsevier Inc. All rights reserved.

• A convenient new procedure for the oxidative cleavage of the bile acid and lanosterol side chains
  作者：M. Fetizon、F.J. Kakis、V. Ignatiadou-Ragoussis

  A new method for the degradation of the side chain of lanosterol and bile acids is described. The cleavage was brought about by the action of molecular oxygen on basic solutions of the phenyl ketones (1, 7, and 15). Thus, the side chains were reduced by two C atoms, leading to the 23,24-bisnor series in appreciable yields. A method for converting the bisnor compounds to 20-ketosteroids is also described

  描述了一种用于降解羊毛甾醇和胆汁酸侧链的新方法。裂解物通过分子氧对苯基酮（的碱性溶液的作用带来的1，7，和15）。因此，侧链被两个C原子还原，从而以可观的收率得到23,24-bisnor系列。还描述了将比斯诺化合物转化为20-酮类固醇的方法。获得的结果表明，降解产物的性质取决于α-氢的酸度，反应介质的碱性强度和溶剂的性质。包括对该机制的简短讨论。
