  Synthesis, in vitro cytotoxicity, and antibacterial studies of new asymmetric bis-1,2,4-triazoles

  摘要：

  A series of asymmetric bis-1,2,4-triazoles (4a-l) were synthesized from respective 1,2,4-triazole-3-thiocarbohydrazides (2a, b) via base catalyzed dehydrative cyclization of thiosemicarbazide intermediates (3a-l). The synthesized compounds were characterized by IR, H-1-NMR, C-13-NMR, and Mass spectral studies. The asymmetric bis-1,2,4-triazole derivatives (4a-l) were evaluated for in vitro antioxidant activity by DPPH radical scavenging assay method. The compounds with significant antioxidant potential were evaluated for in vitro cytotoxicity by MTT assay method against HT29 (Human adenocarcinoma) and MDA-231 (Human breast cancer) cancer cell lines. All the synthesized compounds were evaluated for in vitro antibacterial activity against Bacillus subtilus (ATCC 6633), Staphylococcus aureus (ATCC-25923), Escherichia coli (ATCC-25922), and Pseudomonas aeruginosa (ATCC-27853).
