16.7 µM, making it more potent than the clinically used allopurinol (IC50=30.7 µM). Herein, a structure-activity relationship analysis of the polar part analogs of HC was conducted and an inhibitor was discovered with a potency 13 times that of HC. Kinetic studies have revealed that HC and its active analog inhibit XO in an uncompetitive manner. The binding structure prediction of these inhibitor molecules
羟基
邻苯二酚(HC),是从Piper betle LINN的叶子中获得的。(Piperaceae)可抑制
黄嘌呤氧化酶(XO),IC50值为16.7 µM,使其比临床使用的别
嘌呤醇(IC50 = 30.7 µM)更有效。在此,对HC的极性部分类似物进行了构效关系分析,发现了一种
抑制剂,其效价是HC的13倍。动力学研究表明,HC及其活性类似物以非竞争性方式抑制XO。这些
抑制剂分子与
黄嘌呤的XO配合物的结合结构预测表明,这两种化合物(HC及其类似物)都可以同时与
黄嘌呤和XO形成氢键。
