CQ1373 is a potent RET inhibitor, demonstrating cellular potency with IC50 values of 13.0, 25.7 and 28.4 nM against BaF3 cells expressing CCDC6-RET, CCDC6-RET-G810C and CCDC6-RET-G810R, respectively. CQ1373 exhibits good selectivity toward wild-type RET and solvent front mutants G810C/R with IC50 values of 4.2, 7.1 and 32.4 nM, respectively. CQ1373 inhibits RET phosphorylation and downstream signaling through SHC. CQ1373 induces Apoptosis and cell cycle arrest in BaF3 cells. CQ1373 exhibits anti-tumor efficacy and can be used for cancer research[1].
