Description: Merestinib hydrochloride (LY-2801653) is a novel, potent, orally bioavailable, type-II ATP competitive, slow-off small molecule inhibitor of MET tyrosine kinase with a dissociation constant (Ki) of 2 nM, a pharmacodynamic residence time (Koff) of 0.00132 min(-1) and t1/2 of 525 min. In vitro study showed that 0.01-10 μM LY2801653 was able to completely block HGF-induced DU-145 cell scattering regulated by c-MET kinase, which demonstrated the inhibition of c-MET kinase activity. When LY2801653 was screened with a panel of cell lines, it was found more potent anti-proliferative activity of LY2801653 in those cell lines with MET gene expression than without MET gene expression.
