title: Synthesis and in vitro cytotoxicity studies of certain novel heterocycles derived from bis 1, 2, 4-triazoles and their DNA damage studies.
abstract: Synthesis and evaluation of cytotoxicity of a series of heterocyclic compounds derived from 1, 4-bis-(5- [hydrazinocarbonylmethylthio]-4-phenyl-1,2,4-triazol-3-yl) butane (1a-b) are described. The triazolo-triazoles (9-15) and thiadiazoles (16-18) were prepared from respective thiosemicarbazide intermediates (2-8). The Schiff bases (19-24) were prepared from (1a, b) by reacting with different carboxaldehydes in acetic acid medium. All the synthesized compounds were characterized by IR, NMR and Mass spectral studies. The compounds were evaluated for in vitro cytotoxicity potential using the standard MTT assay against a panel of three human cancer cell lines: Lung carcinoma A-549, Colon carcinoma HT-29 and Breast Cancer MDA MB-231. The DNA damage activity of the compound 24 was evaluated by alkaline comet assay.
