5-Alkenyl or 5-alkynyl-4-anilinopyrimidines were prepared and evaluated for in vitro inhibition of EGFR/Her-2 kinase activity and the growth of tumor cell lines (BT474 and N87). Several of these compounds inhibited the growth of BT474 and N87 at concentrations below 200 nM. Structure-activity relationship studies revealed a critical role for the 5-alkynyl moieties. The representative compound 19 exhibited significant antitumor potency in a mouse xenograft model. (C) 2011 Elsevier Ltd. All rights reserved.
