2,3-Dihydroquinazolin-4(1H)-one derivatives (3a-p) were synthesized in excellent yields. These compounds were screened for antiproliferative activity against A549 cells and were found as potent cytotoxicity. Compounds A4, A8, A10 found to be more promising antiproliferative against the lung carcinoma A549 cells. IC50 values for compounds A4, A8 and A10 were found to be 8.6, 8.9 and 8.1 μg/L against A549 cells, respectively.

A highly efficient protocol was developed for the synthesis of 3-(indoline-1-carbonyl)-N-(substituted)benzenesulfonamide compounds with excellent yields. The in vitro anticancer activity of the new 3-(indoline-1-carbonyl)-N-(substituted)benzenesulfonamide derivatives against A549 (lung cancer cell), HeLa (cervical), MCF-7 (breast cancer cell) and Du-145 (prostate cancer cell) cell lines were studied. Most of the tested compounds showed anticancer activity (IC50 values ranged between 1.98 and 9.12 µM against different cell lines).
