In our previous publication (Blaney, J. M.; Dietrich, S. W.; Reynolds, M. A.; Hansch, C. J. Med. Chem. 1979, 22, 614), correlation equations were presented for the inhibition of bovine liver and Escherichia coli dihydrofolate reductase (DHFR) by 5-(substituted benzyl)-2,4-diaminopyrimidines. These equations brought out differences in the way these two enzymes interact with substituents, which explain
在我们以前的出版物中(Blaney,JM; Dietrich,SW; Reynolds,MA; Hansch,CJ Med。Chem。1979,22,614),提出了相关方程式对牛肝和大肠杆菌二氢叶酸还原酶(DHFR)的抑制作用。 5-(取代的苄基)-2,4-二氨基嘧啶。这些方程式揭示了这两种酶与取代基相互作用的方式的差异,这解释了甲氧苄啶等药物的高选择性。我们在本报告中测试并进一步开发了这些方程式。特别令人感兴趣的是,我们先前发布的大肠杆菌DHFR相关方程可准确预测目前在临床上使用的甲氧苄氨嘧啶(tetroxoprim)的商业竞争者的效力。我们认为,可以通过两个相关方程设计甲氧苄啶的新的有效竞争者。
