| 描述 | The receptor tyrosine kinase, MET proto-oncogene, receptor tyrosine kinase (c-MET) is a high-affinity receptor for hepatocyte growth factor (HGF), and its downstream v-akt murine thymoma viral oncogene homolog (AKT) and mitogen-activated protein kinase (ERK) pathways are regulated by HGF/c-MET. The HGF/c-MET axis is involved in cancer progression, metastasis, and acquired resistance[3]. HGF/c-MET signaling is often highly activated in tumors because of various mechanisms. MET is a high-affinity tyrosine kinase receptor (RTK) for hepatocyte growth factor (HGF). HGF binding triggers the dimerization of MET receptors, then activation of multiple intracellular pathways such as mitogen-activated protein kinase (MAPK), phosphatidylinositol 3-kinase (PI3K) and focal adhesion kinase (FAK). Tivantinib (ARQ-197) inhibits MET by binding to the inactive conformation of MET to stabilize this conformation. This prevents MET phosphorylation and dampens downstream signaling, thereby resulting in growth inhibition and induction of apoptosis in solid tumors. Tivantinib can induce a G2/M arrest and promoted apoptosis by both intrinsic and extrinsic pathway. Tivantinib is a highly selective, orally administered, non-ATP competitive inhibitor of the MET, with an inhibitory constant (Ki) of 355 nM[4]. Tivantinib also inhibited constitutive p-MET and HGF-induced p-MET in several type of tumor cells with an IC50 of 100 to 300 nM. In vivo experiment, MHCC97L xenograft mice were treated daily with an oral dose of tivantinib at 100 mg/kg or 200 mg/kg for 15 days. Tivantinib displayed a good anti-tumor effect on MHCC97L xenografts and tumor growth inhibition (TGI) rates were 30.9% and 64.6%, respectively[4]. In vivo study, EBC-1 cells were treated with the indicated concentrations of Tivantinib and incubated concentrations ranging from 1-10μM for another 72h. It was found that tivantinib treatment inhibited tubulin polymerization in a concentration-dependent manner but did not inhibit c-MET and its downstream AKT and ERK signaling pathways[3]. | ||
