A series of 2-aminopyridine-3-carboxamide derivatives against c-Met were designed and synthesized by employing bioisosteric replacement of heterocyclic moieties with the amide bond. The structure-activity relationship (SAR) at various positions of the scaffold was explored. In this study, a promising compound (S)-24o with a c-Met IC50 of 0.022 mu M was identified. The compound exhibited dose-dependent inhibition of the phosphorylation of c-Met as well as downstream signaling in EBC-1 cells. Furthermore, the interactive binding model of (S)-24o with c-Met was elucidated by virtue of a molecular modeling study. (C) 2012 Elsevier Ltd. All rights reserved.
