MK-2461 is a potent inhibitor of Met, Flt1, Flt 3, Ron, PDGFRβ, and Mer with IC50 of 2.5 nM, 10 nM, 22 nM, 7 nM, and 24 nM, respectively.
c-Met, also named as hepatocyte growth factor receptor (HGFR) is a receptor tyrosine kinase that is essential for embryonic development and would healing. In many tumor cells, this molecular is overexpressed or mutated and was found to play important roles in tumor cell proliferation, survival, invasion, metastasis and angiogenesis.
In vitro, MK-2461treatment blocked hepatocyte growth factor/c-Met- dependent mitogenesis, migration, cell scatter, and tubulogenesis 1.
In a murine xenograft model of c-Met-dependent gastric cancer, oral administration of MK-2461 at a dosge of 100 mg/kg twice daily effectively inhibited c-Met signaling and tumor growth 1. Consistently, MK-2461 inhibited the tumor growth which was formed by s.c. injection of mouse NIH-3T3 cells expressing oncogenic c-Met mutants 1. These evidence support the preclinical development of MK-2461 for cancer therapy.

MK-2461, a novel multitargeted kinase inhibitor, preferentially inhibits the activated c-Met receptor.[Pubmed:20145145]
Cancer Res. 2010 Feb 15;70(4):1524-33.
The receptor tyrosine kinase c-Met is an attractive target for therapeutic blockade in cancer. Here, we describe MK-2461, a novel ATP-competitive multitargeted inhibitor of activated c-Met. MK-2461 inhibited in vitro phosphorylation of a peptide substrate recognized by wild-type or oncogenic c-Met kinases (N1100Y, Y1230C, Y1230H, Y1235D, and M1250T) with IC(50) values of 0.4 to 2.5 nmol/L. In contrast, MK-2461 was several hundredfold less potent as an inhibitor of c-Met autophosphorylation at the kinase activation loop. In tumor cells, MK-2461 effectively suppressed constitutive or ligand-induced phosphorylation of the juxtamembrane domain and COOH-terminal docking site of c-Met, and its downstream signaling to the phosphoinositide 3-kinase-AKT and Ras-extracellular signal-regulated kinase pathways, without inhibiting autophosphorylation of the c-Met activation loop. BIAcore studies indicated 6-fold tighter binding to c-Met when it was phosphorylated, suggesting that MK-2461 binds preferentially to activated c-Met. MK-2461 displayed significant inhibitory activities against fibroblast growth factor receptor (FGFR), platelet-derived growth factor receptor, and other receptor tyrosine kinases. In cell culture, MK-2461 inhibited hepatocyte growth factor/c-Met-dependent mitogenesis, migration, cell scatter, and tubulogenesis. Seven of 10 MK-2461-sensitive tumor cell lines identified from a large panel harbored genomic amplification of MET or FGFR2. In a murine xenograft model of c-Met-dependent gastric cancer, a well-tolerated oral regimen of MK-2461 administered at 100 mg/kg twice daily effectively suppressed c-Met signaling and tumor growth. Similarly, MK-2461 inhibited the growth of tumors formed by s.c. injection of mouse NIH-3T3 cells expressing oncogenic c-Met mutants. Taken together, our findings support further preclinical development of MK-2461 for cancer therapy.
Discovery of a 5H-benzo[4,5]cyclohepta[1,2-b]pyridin-5-one (MK-2461) inhibitor of c-Met kinase for the treatment of cancer.[Pubmed:21608528]
J Med Chem. 2011 Jun 23;54(12):4092-108.
c-Met is a transmembrane tyrosine kinase that mediates activation of several signaling pathways implicated in aggressive cancer phenotypes. In recent years, research into this area has highlighted c-Met as an attractive cancer drug target, triggering a number of approaches to disrupt aberrant c-Met signaling. Screening efforts identified a unique class of 5H-benzo[4,5]cyclohepta[1,2-b]pyridin-5-one kinase inhibitors, exemplified by 1. Subsequent SAR studies led to the development of 81 (MK-2461), a potent inhibitor of c-Met that was efficacious in preclinical animal models of tumor suppression. In addition, biochemical studies and X-ray analysis have revealed that this unique class of kinase inhibitors binds preferentially to the activated (phosphorylated) form of the kinase. This report details the development of 81 and provides a description of its unique biochemical properties.
Design and synthesis of novel substituted naphthyridines as potential c-Met kinase inhibitors based on MK-2461.[Pubmed:26077488]
Bioorg Med Chem Lett. 2015 Aug 15;25(16):3251-5.
Two series of novel 1,5-naphthyridine and 1,6-naphthyridine derivatives were designed and synthesized based on the c-Met kinase inhibitor MK-2461 under the guidance of scaffold hopping strategy. All were tested on c-Met kinase and in vitro anti-tumor activities against Hela and A549 cell lines. The results indicated that 1,6-naphthyridine was a more promising c-Met inhibitory structure core compared with 1,5-naphthyridine. Among them, 26b and 26c showed the best enzymic and cytotoxic activities. The western blot experiments implied that the cytotoxic activity of 26c might be partially through suppressing the phosphorylation of c-Met kinase.
