New sulfonamide derivatives have been synthesized and tested as antitumor agents. All newly synthesized compounds were tested in vitro against 60 lines of human cancer cells. Compound VIIb shows broad-spectrum activity with a mean inhibition value of 91.67% against all cell lines. It exhibited potent anticancer activity with GI50 values of 1.06-8.92 μM relative to most of the tested cancer cell lines. Compound VIIb has been tested for enzyme inhibition activity toward vascular endothelial growth factor receptor 2, where VEGFR-2 was potently inhibited at a l
