  Inhibitory potency of lithocholic acid analogs and other bile acids on glucuronosyltransferase activity in a colon cancer cell line

  摘要：

  The effectiveness of analogs of lithocholic acid and other bile acids in inhibiting glucuronosyltransferase activity in a colon cancer cell line was measured in order to identify structural features critical for inhibition of the enzyme. Analogs of lithocholic acid with modifications of the side chain (2-7) were synthesized, in part, to study their inhibitory effects on glucuronosyltransferase activity. Bishomolithocholic acid (4) was synthesized from the iodo derivative (9) by a free radical Michael type reaction using tris(trimethylsilyl)silane as a free radical mediator.

  三苯甲基保护的硫醇和醇的光催化裂解

  摘要：

  我们报告了在 pH 中性条件下三苯甲基硫醚或醚的可见光光催化裂解。该方法导致以中等到极好的收率形成相应的对称二硫化物和醇。该协议只需要添加合适的光催化剂和光使其与多种功能正交，包括酸不稳定保护基团。相同的条件可用于直接将三苯甲基保护的硫醇转化为不对称的二硫化物或硒硫化物，并在固相有机合成中裂解三苯甲基树脂。
