In an effort to find novel N-arylsulfonylimidazolidinones as highly potent anticancer agent, the structure–activity relationship of ethyl 2-methyl-4-(2-oxo-4-phenylimidazolidin-1- ylsulfonyl) phenylcarbamate was explored through synthesis and evaluation of in vitro cytotoxicity of its analogs against HCT116, A549 and NCL-H460 cancer cell lines. Among the synthesized derivatives, the carbamate analogs (4a–f and 4k–p) exhibited superior ...
