Abstract

Abstract : Discovery of a new class of 1 H - pyrrorole [2, 3-b]pyridine FGFR inhibitors with high ligand efficiency. Abstract : Abnormal activation of FGFR signaling pathway plays an essential role in various types of tumors. Therefore, targeting FGFRs represents an attractive strategy for cancer therapy. Herein, we report a series of 1 H -pyrrolo[2, 3- b ]pyridine derivatives with potent activities against FGFR1, 2, and 3. Among them, compound 4h exhibited potent FGFR inhibitory activity (FGFR1–4 IC50 values of 7, 9, 25 and 712 nM, respectively). In vitro, 4h inhibited breast cancer 4T1 cell proliferation and induced its apoptosis. In addition, 4h also significantly inhibited the migration and invasion of 4T1 cells. Furthermore, 4h with low molecular weight would be an appealing lead compound which was beneficial to the subsequent optimization. In general, this research has been developing a class of 1 H -pyrrolo[2, 3- b ]pyridine derivatives targeting FGFR with development prospects.
