Abstract
AIM To study on synthesis and antibacterial activity evaluation of polyheterocycles. METHODS The condensation of 4-amino-3-pyridin-3-yl-4H-[1,2,4] triazole-5-thiol with 2-chloromethyl-5-substituted phenyl-[1,3,4] oxadiazoles gave the corresponding title heterocycle amines, and the in vitro antibacterial activity was primarily evaluated by the method of cup-plate diffusion solution. RESULTS Twelve novel compounds were synthesized, and their structures were confirmed by IR, 1H NMR, MS and element analysis. Biological screening results demonstrated that most of the compounds prepared showed good antibacterial activity. CONCLUSION Oxadiazoles incorporting pyridyl triazole ring may be a pharmacophor structure in the molecule for developing antibacterial candidate drugs.
