The synthesized compounds were evaluated against Mtb (H(37)Rv and Dormant stage H37Ra), their cytotoxicity was assessed (HepG2 and A549 cell lines), and selectivity toward Mtb was evaluated by testing against other bacterial strains. Some derivatives showed promising activity along with low cytotoxicity. The most potent compound in the whole cell assay (MIC 0.325 mu M against H(37)Rv) showed selectivity in the enzyme assay and exhibited synergy with second line anti-TB agent p-amino salicylic acid. This study therefore provides promising molecules for further development as antituberculosis DHFR inhibitors.</p>10aDiamino triazine10adihydrofolate reductase10aenzyme assay10amolecular modeling10aMycobacterium tuberculosis10aselectivity10asynergy1 aLele, Arundhati, C.1 aRaju, Archana1 aKhambete, Mihir, P.1 aRay, M., K.1 aRajan, M., G.
