A series of lipophilic soft drugs structurally related to the nonclassical dihydrofolate reductase (DHFR) inhibitors trimetrexate and piritrexim have been designed, synthesized, and evaluated in DHFR assays, with special emphasis on the inhibition of P. carinii DHFR. The best inhibitors, encompassing an ester bond in the bridge connecting the two aromatic systems, were approximately 10 times less potent

It is disclosed that 5-methyl-5-deazamethotrexate and 5-methyl-5-deaza-10-ethylaminopterin are more than 10 times as potent as 5-deazamethotrexate in the L1210 cell growth inhibition test.
