Abstract

A series of new N-benzoyl-N'-triazine thiourea derivatives have been synthesized via the reaction of 4-amino-6-methyl-3-thioxo-3,4-dihydro-1,2,4-triazin-5(2H)-one with benzoyl chloride derivatives and ammonium thiocyanate in acetone under reflux conditions. 4-Amino-6-methyl-3-thioxo-3,4-dihydro-1,2,4-triazin-5(2H)-one was prepared from the reaction of two equivalents of hydrazine hydrate with carbon disulfide and sodium pyruvate. The chemical structure of thioureas was confirmed using FT-IR, 1H NMR, 13C NMR, and high-resolution mass spectrometry, and elemental analysis. The synthesized thioureas were assayed for their antibacterial activity against both gram-positive (Micrococcusluteus and Bacilluscereus) and gram-negative (Pseudomonasaeruginosa and Escherichiacoli) bacteria using the agar well diffusion method.
