文摘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.
文摘目的:考察不同模板分子对距离比较法(DIStance COmparison,DISCO)构建HMG-CoA还原酶抑制剂药效团模型的影响。方法:以MDDR数据库中作用于大鼠肝细胞的13个HMG-CoA还原酶抑制剂为训练集,将活性最高的6个活性分子逐一作为模板分子,用DISCO方法构建的HMG-CoA还原酶抑制剂三维药效团模型和比较分子力场分析法(Comparative Molecular Field Analysis,CoMFA)进行分析。结果:最优HMG-CoA还原酶抑制剂药效团模型包含两个氢键受体和两个疏水中心,其模板分子的刚性和活性适中。结论:利用DISCO方法构建药效团模型时,合理选择模板分子是保证药效团可靠的关键因素之一。
