Quantitative structure-activity relationships (QSAR) have been derived for the action of 68 5-(substituted benzyl)-2,4-diaminopyrimidines on dihydrofolate reductase (DHFR) from Lactobacillus casei and chicken liver. The QSAR are analyzed with respect to the stereographics models of the active sites of the enzymes and found to be in good agreement. Using these QSAR equations, we have attempted to design
定量的构效关系(QSAR)已经推导了68个5-(取代的苄基)-2,4-二氨基嘧啶对干酪乳杆菌和鸡肝中二氢叶酸还原酶(DHFR)的作用。根据酶活性位点的立体模型对QSAR进行了分析,发现QSAR具有良好的一致性。使用这些QSAR方程,我们尝试设计对细菌酶具有更高选择性的新型甲氧苄啶型抗叶酸剂。讨论了开发选择性抑制剂的一般问题。
