Synthesis and Anticancer Evaluation of Benzenesulfonamide Derivatives

A highly efficient protocol was developed for the synthesis of 3-(indoline-1-carbonyl)-N-(substituted) benzene sulfonamide analogs with excellent yields. The new 3-(indoline-1-carbonyl)-N-(substituted) benzene sulfonamide derivatives (4a-g and 5a-g) were evaluated in vitro anticancer activity against a series of different cell lines like A549 (lung cancer cell), HeLa (cervical), MCF-7 (breast cancer cell) and Du-145 (prostate cancer cell) respectively. The results of the anticancer activity data revealed that most of the tested compounds showed IC 50 values from 1.98 to 9.12 μ M in different cell lines. Compounds 4b, 4d, 5d, and 5g were the most potent, with IC 50 values ranging from 1.98 to 2.72 μ M in different cell lines.
