Abstract: Fibroblast growth factor receptors (FGFR1-4) are promising therapeutic targets in many cancers. With the resurgence of interest in irreversible inhibitors, efforts have been directed to the discovery of irreversible FGFR inhibitors. Currently, several selective irreversible inhibitors are being evaluated in clinical trials that could covalently target a conserved cysteine in the P-loop of FGFR. In this article, we used a structure-guided approach that is rationalized by a computer-aided simulation to discover the novel and irreversible pan-FGFR inhibitor, 9g, which provided superior FGFR in vitro activities and decent selectivity over VEGFR2 (vascular endothelia growth factor receptor 2). In in vivo studies, 9g displayed clear antitumor activities in NCI-H1581 and SNU-16 xenograft mice models. Additionally, the diluting method confirmed the irreversible binding of 9g to FGFR.
