Design, Synthesis and Anticancer Activity of Some Novel 1,2,4-triazoles Carrying Biologically Active Sulfonamide Moieties

Thirteen novel 1, 2, 4-triazoles incorporating a biologically active sulfonamide moieties 1-13 were designed and synthesized. The structures of the prepared compounds were elucidated on the basis of elemental analyses, IR, H-NMR, C-NMR and mass spectral data. All the newly synthesized compounds were evaluated for their in vitro anticancer activity against various cancer cell lines. The corresponding triazole carrying a biologically active free sulfonamide with unsubstituted phenyl ring 1 and triazole bearing sulfonamide with dimethylpyrimidine 11 were the most potent in this study which showed higher activity than the reference drug 2í,7í-dichlorofluorescein (DCF). Cytotoxic screening of the tested compounds could offer an encouraging framework in the field that may lead to the discovery of potent anticancer activity.
