Title: Quantitative structure-activity relationships of 2, 4-diamino-5-(2-X-benzyl)pyrimidines versus bacterial and avian dihydrofolate reductase.

Authors: Selassie CD, Gan WX, Kallander LS, Klein TE.

Abstract: 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 binding process and subsequent inhibition of the catalytic process in both the prokaryotic and eucaryotic DHFRs. Comparisons between the two QSARs reveal subtle differences at specific positions which can be optimized to design more selective antibacterial agents.
