Design and synthesis of novel 4-phenyl-1-arylsulfonylimidazolones 3 and 4-phenyl-3-arylsulfonylimidazolones 4 and evaluation of their cytotoxic activity against eleven human cancer cell lines and two murine leukemia cell lines in vitro were performed. As a result, a series of 4-phenyl-1(N)-arylsulfonylimidazolones (3) has been found to be the potential anticancer agent. Compounds 3b, 3c, and 3d exhibit strong activity as indicated by their $IC_{50}$ values 0.39, 3.19, $0.31{\mu}g/mL$ against A549 and 0.80, 0.48, $0.0007{\mu}g/mL$against SK-Mel-2, respectively. These compounds also possess much more potent activity (10-1000 times) than LY186641 against eleven other cell lines.
