In vitro study | AMG 337 effectively inhibit wild-type MET and the enzyme activity of some MET mutants in papillary cell carcinoma. The inability of AMG 337 to inhibit Y1230 and D1228 MET mutants may be due to the destruction of the inactive conformation of the activation loop of the MET kinase region. AMG 337 also inhibited MET phosphorylation induced by HGF in PC3 cells with an IC50 of 5 nM. AMG 337 inhibits the proliferation of MET-dependent cancer cells and plays a role in cell proliferation and survival through PI3K and MAPK signaling pathways in MET-amplified gastric cancer cells. |
in vivo studies | AMG 337(0.75 mg/kg) can inhibit the phosphorylation of Gab-1 greater than 90%. It was well tolerated with complete inhibition of MET after 24 hours of continuous administration. Therefore, AMG 337 has the clinical attribute of testing MET effect in human cancer. |
