In vitro: 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.
In vivo: 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.
| Cell Experiment | |
|---|---|
| Cell lines | GTL-16 and SNU-16 cell lines |
| Preparation method | For GTL-16 and SNU-16 viability assays, cells are seeded in 96-well microplates at the appropriate density in media containing 10% FCS and supplemented 48 hours later with serial dilutions of S49076 in a final volume of 150 μL per well. After 96 hours (GTL-16) or 120 hours (SNU-16) incubation, 15 μL of a solution of 5 mg/mL MTT is added to each well and the plates are incubated for 4 hours at 37℃. The formazan metabolite is solubilized in SDS for SNU-16 and, following removal of the MTT solution, in DMSO for GTL-16. Global cell viability is estimated by measurement of optical density at 540 nm. |
