Piritrexim (PTX) (1), a lipophilicinhibitor of the human dihydrofolate reductase, has been evaluated as an anticancer agent. The synthesis of four structural variations (2-5) of PTX is reported. The PTX analogues 2-5 were obtained by reaction of suitable C3-building blocks with pyrimidine-2,4,6-triamine (14) or with cyanacetamide (7) and guanidine (10). The evaluation of 2-4 for antitumor activity
