HMG-CoA还原酶抑制剂的3D-QSAR研究

3-羟基-3-甲基戊二酰辅酶A还原酶（HMG—CoAR）是肝脏中胆固醇合成的限速酶．酶的底物HMG—CoA和NADP分子分别与酶的L区和S区充分结合，催化HMG—CoA还原裂解生成甲羟戊酸（mevalonate）．甲羟戊酸经一系列反应生成胆固醇，而高胆固醇和高脂蛋白是心血管疾病的主要危险因素，因此HMG—CoAR是治疗心脑血管疾病、冠心病、心肌梗塞主要靶标酶．他汀类药物可以选择性地进入肝脏HMG—CoAR活性空腔，

3D-QSAR study of statin inhibitors of HMG-CoA reductase

HMG-CoA reductase converts HMG-CoA to mevalonate,with this catalysis constituting a committed step in the biosynthesis of cholesterol.So,it's primary drone in treatment coronary artery disease.At present,several statins are available in the drug market,however,up to now the quantitative structure-activity relationship of all of known inhibitors hasn't been reported.In order to provide a theoretical guide for the synthesis of novel inhibitors,the quantitative structure-activity relationship of the inhibitors of HMG-CoA reductase were performed by using 3D-QSAR approach: comparative molecular field analysis(CoMFA).The computed obtained CoMFA model with(q~2=0.4,) r~2=0.955,SE=0.110,F=85.335.It not only can be used to explain the structure-activity relationship of compound but also has powerful predictive ability.
