A series of novel sorafenib derivatives, 9a–w, was designed and synthesized in high yields using various substituted anilines, and their antiproliferative activities against HCT116, PC-3 and MDA-MB-231 cell lines were also evaluated and described. All compounds exhibited potent antiproliferative activity against HCT116 and PC-3 cells with IC50= 2.8–52.0 and 2.2– 45.6 μM; compounds 9p and 9q demonstrated competitive antiproliferative activities to ...
