Quantitative structure-activity relationships (QSAR) have been formulated for a set of 15 2,4-diamino-5-(2-X-benzyl)pyrimidines versus dihydrofolate reductase from Lactobacillus casei and chicken liver. QSARs were also developed for comprehensive data sets containing mono-, di-, and trisubstituted benzyl derivatives. Particular emphasis was placed on the role played by ortho substituents in the overall
定量结构-活性关系(QSAR)已针对一组15个2,4-二氨基-5-(2-X-苄基)嘧啶与干酪乳杆菌和鸡肝中的二氢叶酸还原酶进行了配制。还为包含单,二和三取代的苄基衍生物的综合数据集开发了QSAR。特别强调了在原核和真核DHFR中,邻位取代基在整个结合过程中的作用以及随后对催化过程的抑制作用。两种QSAR的比较显示出特定位置的细微差异,可以对其进行优化以设计更具选择性的抗菌剂。
