In view of the pharmacological activities of 1,2,4-triazinones, a series of 4-amino-6-arylfuranylmethyl-3-mercapto-1,2,4-triazin-5(4H)-ones 7 have been synthesized by refluxing pyruvic acids 5 in ethanol with thiocarbohydrazide 6 on a steam-bath. The structures of 7 are confirmed by elemental analysis, IR, NMR and mass spectral data. Also, these compounds 7 have been screened for antibacterial activities against E. coli, S.aureus, P. aeruginosa and G. bacillus. Their MIC values are determined. The results indicate that among the compounds tested, compounds 7a and 7c carrying p-chloro and p-bromo substituents show excellent antibacterial activity against all the bacteria tested. It is concluded that compounds 7a, 7c, 7d and 7f may prove to be promising antibacterial agents.
