This paper describes the synthesis of 4′-substituted and 3′,4′-disubstituted 5-benzyl-2,4-diaminopyrimidines as selective inhibitors of leishmanial and trypanosomal dihydrofolate reductase. Compounds were then assayed against the recombinant parasite and human enzymes. Some of the compounds showed good activity. They were also tested against the intact parasites using in vitro assays. Good activity was found against Trypanosoma cruzi, moderate activity against Trypanosoma brucei and Leishmania donovani. Molecular modeling was undertaken to explain the results. The leishmanial enzyme was found to have a more extensive lipophilic binding region in the active site than the human enzyme. Compounds which bound within the pocket showed the highest selectivity.

2,4-Diamino-5-benzylpyrimidines 1-23 with lipophilic substitution in the benzylic moiety were synthesized by the morpholino-anilino-procedure. Their effects against various mycobacteria were verified by MIC (minimum inhibitory concentration) in whole cells and I50-measurements in whole cell and cell-free systems. Especially the substances 7-12 are strong inhibitors of some atypical mycobacterial strains which are sometimes associated with tuberculosis in the elderly and with AIDS. They might be promising candidates for therapy.
