DDR1 is considered as a promising target for cancer therapy, and selective inhibitors against DDR1 over other kinases may be considered as promising therapeutic agents. Herein, we have identified a series of 3′-(imidazo[1,2-a]pyrazin-3-yl)-[1,1′-biphenyl]-3-carboxamides as novel selective DDR1 inhibitors. Among these, compound 8v potently inhibited DDR1 with an IC 50 of 23.8 nM, while it showed less inhibitory activity against DDR2 (IC 50 = 1740 nM) and negligible activities against Bcr-Abl (IC 50 > 10 μM) and c-Kit (IC 50 > 10 μM). 8v also exhibited excellent selectivity in a KINOMEscan screening platform with 468 kinases. This compound dose-dependently suppressed NSCLC cell tumorigenicity, migration, and invasion. Collectively, these studies support its potential application for treatment of NSCLC.
