Inhibition of dihydrofolate reductase. Structure-activity correlations of quinazolines

Abstract
A quantitative structure-activity relationship (QSAR) was formulated for antitumor quinazolines causing 50% inhibition of liver dihydrofolate reductase. The QSAR for the quinazolines is compared with QSAR for triazine and pyrimidine inhibitors. The 3 QSAR suggest new possibilities for the design of inhibitors of mammalian dihydrofolate reductase.
