| Summary: | This work represents the synthesis and characterization some new versatile intermediates namely4-amino-1,2,4-triazole-5(4<em>H</em>)-thionederivatives in a one-step fusion method. The method works to be superior compared to the existing method by Reed and Handel which consists of four steps. The antibacterial activity of compounds is tested against <em>Escherichia coli, Bacillus subtilis, Pseudomonas aeruginosa, Staphilococcusaureus</em>. The compounds exhibited species specific activity. Among the tested compounds,<strong>1a</strong> and <strong>1b</strong> exhibited good activity at moderately low concentration (31.25µg/mL)against tested strains of bacteria.DPPH (1,1-diphenyl-2-picryl-hydrazyl), FRAP (ferric reducing antioxidant power) and Lipid peroxidation assays are performed to determine the<em>in vitro</em> antioxidant activities. The compound <strong>1e</strong> exhibited good antioxidant activity among the tested compounds.
