Biological Activity

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.
Incubation time 96 h or 120 h
Animal Experiment
Animal models Female balb/c and swiss nu/nu mice
Formulation 1% (w/v) hydroxyethylcellulose in ammonium acetate buffer pH 4.5
Dosages 50 or 100 mg/kg
Administration oral administration

Animal A (mg/kg) = Animal B (mg/kg) multiplied by  Animal B Km
Animal A Km

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.
