Abstract

In a continuing effort to design small-molecule inhibitors of dihydrofolate reductase (DHFR) that combine the enzyme-binding selectivity of 2, 4-diamino-5-(3', 4', 5'-trimethoxybenzyl) pyrimidine (trimethoprim, TMP) with the potency of 2, 4-diamino-5-methyl-6-(2', 5'- dimethoxybenzyl) pyrido [2, 3-d] pyrimidine (piritrexim, PTX), seven previously undescribed 2, 4-diamino-5-[2'-methoxy-5'-(substituted benzyl)] pyrimidines were synthesized in which ...
