Merestinib (LY2801653) is a small molecule that has been shown in vitro to be a reversible type II ATP-competitive slowoff inhibitor of MET tyrosine kinase with a dissociation constant (Ki) of 2 nM, a pharmacodynamic residence time (Koff) of 0.00132 min−1 and a half-life (t1/2) of 525 min. Preclinical testing also has shown merestinib to inhibit several other receptor tyrosine oncokinases including MST1R, FLT3, AXL, MERTK, TEK, ROS1, NTRK1/2/3, and DDR1/2 and the serine/threonine kinases MKNK1/2. Merestinib is being investigated in a phase II clinical trials in patients with biliary tract cancer, non-small cell lung cancer and solid tumours.
