S49076 potently blocks cellular phosphorylation of MET, AXL, and FGFRs and inhibits downstream signaling in vitro and in vivo. In cell models, S49076 inhibits the proliferation of MET- and FGFR2-dependent gastric cancer cells, blocks MET-driven migration of lung carcinoma cells, and inhibits colony formation of hepatocarcinoma cells expressing FGFR1/2 and AXL. S49076 inhibits viability, motility, and three-dimensional colony formation of cancer cells expressing MET, AXL, or FGFRs.S49076 shows marked antitumor activity in MET- and FGFR-dependent tumor xenografts at well-tolerated doses. S49076 has high distribution to tumors, in which the half-life for the dose of 3.125 mg/kg is approximately 7 hours versus less than 2 hours in the blood. At doses of 6.25 mg/kg and higher, more than 50% inhibition of MET phosphorylation is retained at 16 hours. S49076 is also active in a bevacizumab-resistant model and totally inhibits the growth of colon carcinoma xenografts in association with bevacizumab. |
