Merestinib (LY2801653) is a small molecule that has been shown in vitro to be a reversible type II ATP-competitive inhibitor of MET. Pre-clinical 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.
