INCB-28060(free base) is a novel, ATP-competitive inhibitor of c-MET kinase with an IC50 with 0.13 nM.INCB28060 exhibits picomolar enzymatic potency and is highly specific for c-MET with more than 10, 000-fold selectivity over a large panel of human kinases. This inhibitor potently blocks c-MET phosphorylation and activation of its key downstream effectors in c-MET-dependent tumor cell lines. As a result, INCB 28060 potently inhibits c-MET-dependent tumor cell proliferation and migration and effectively induces apoptosis in vitro.
