| 名称 | Merestinib dihydrochloride |
| 描述 | Merestinib dihydrochloride (LY2801653 dihydrochloride) is an orally available kinase inhibitor with antitumor activity that inhibits MET, AXL, RON, and MKNK1/2, and inhibits the growth of NTRK fusion-carrying tumors. |
| 体外活性 | Merestinib dihydrochloride is a potent, orally bioavailable c-Met inhibitor with a Ki value of 2 nM and significant antitumor activity. In addition, Merestinib dihydrochloride showed significant antitumor activity against MST1R (IC50=11 nM), FLT3 (IC50=7 nM), AXL (IC50=2 nM), MERTK (IC50=10 nM), TEK (IC50=63 nM), ROS1, DDR1/2 (IC50=0.1/7 nM) and MKNK1/2 (IC50=7 nM) showed potent activity.
Merestinib dihydrochloride affected MET pathway-dependent cell scattering and proliferation. In HGF-stimulated H460 cells, the mean IC50 value for Merestinib dihydrochloride on MET autophosphorylation was 35.2 nM, compared to 59.2 nM in S114 cells. Transfection of MET variants gave cells growth factor independence, and treatment with Merestinib dihydrochloride was able to inhibit the growth of these MET variant clones with IC50 values ranging from approximately 3-fold more potent (V1092I) to approximately 6-fold less potent (L1195V) compared to MET wild-type sequences.

| 体内活性 | Merestinib dihydrochloride showed significant antitumor effects in a MET-amplified xenograft model (MKN45), a MET autocrine model (U-87MG and KP4), and a MET overexpression model (H441), as well as in vivo vasculature normalization. As a type II ATP-competitive inhibitor, Merestinib dihydrochloride is a slow dissociating inhibitor of MET tyrosine kinase with a pharmacodynamic residence time (Koff) of 0.00132 min^-1 and a half-life (t1/2) of 525 min.Merestinib dihydrochloride treatment inhibited MET phosphorylation with a combined TED50 (50% targeted inhibitor dose) of 1.2 mg/kg and TED90 (90% targeted inhibitor dose) of 7.4 mg/kg.With Merestinib dihydrochloride (20 mg/kg), TFK-1 tumor growth was significantly lower than that of the control group. In addition, Merestinib dihydrochloride effectively inhibited the growth of intrahepatic and extrahepatic cholangiocarcinoma (CCC) xenograft tumors. [1][2] |
