Original Research


In the present study, synthesis of a series of some novel 3-(Quinolin-3-yl)-5,7-dimethyl-1,2,4-triazolo[4,3-a]pyrimidine derivatives (4ae) has been achieved by oxidative cyclization of new pyrimidinyl hydrazone intermediates (3ae) using hypervalent iodine reagent(III) under mild conditions. The structures of all synthesized compounds were established on the basis of IR, NMR (1H and 13C), mass spectral data, and elemental analysis. All compounds were evaluated for their DNA photocleavage activity. Compounds 4a, 4b, 4d and 3ae were found to possess good activity at 40 μg/μl concentration and were mainly responsible for the conversion of supercoiled form of DNA into open circular form. Further, docking study was carried out using Molegro Virtual Docker version 2010.4.2.0 using PDB (1AB4) in support of the results obtained.
