Synthesis, Evaluation and Characterization of Some 1,3,4-Triazole-2-one Derivatives as Antimicrobial Agents

Abstract

A series of novel compounds like 3[(phenyl substituted)-5-methyl-1(Benzosulphonylamine)]-1,3,4-triazole-2-ones II(a-f) were synthesized by treating 4-amino-1-phenyl-3-methyl-5-oxo-1,2,4-triazoles with benzene sulphonyl chloride using pyridine as solvent. Similarly by using 4-amino-1-aryl-3-methyl-5-oxo-1,2,4-triazoles and acetic anhydride as starting material 3[(phenyl substituted)-5-methyl-1(acetylamino)]-1,3,4-triazole-2-ones III(a-f) were synthesized and also 3[(phenyl substituted)-5-methyl-1(chloroacetyl)]-1,3,4-triazole-2-ones I(a-f) were synthesized by treating 4-amino-1-aryl-3-methyl-5-oxo-1,2,4-triazoles with chloroacetyl chloride in presence of a non-polar solvent like benzene. Elemental analysis, GCMS, IR, and ¹H NMR confirmed the structures of the newly synthesised compounds. The newly synthesized compounds are also screened for their antibacterial, antifungal and anti-inflammatory activities.
