AMG-337

AMG-337 is a potent, orally active, selective MET kinase inhibitor with IC₅₀ values of 1, 1, 4.7, 5, 21.5, 1077 and >4000 nM of WT MET, H1094R MET, M1250T MET, HGF-stimulated pMET (PC3 cells) MET, V1092I MET, Y1230H MET, and D1228H MET, respectively. AMG 337 inhibits the phosphorylation of MET and downstream effectors in MET-amplified cancer cell lines, resulting in an inhibition of MET-dependent cell proliferation and induction of apoptosis^[1][2]. IC50 & Target: IC₅₀: 1 (WT MET), 1 (H1094R MET), 4.7 (M1250T MET), 5 (HGF-stimulated pMET (PC3 cells) MET), 21.5 (V1092I MET), 1077 (Y1230H MET) and >4000 nM (D1228H MET)^[1] In Vitro: AMG 337 (0-3 µM; 72 h) inhibits proliferation in MET-dependent cancer cell lines^[1].
AMG 337 (0-300 nM; 0-24 h; MKN-45, SNU-620, and SNU-5 cells) inhibits signaling through the PI3K and MAPK pathways in MET-amplified gastric cancer cell lines, resulting in an inhibition of MET-dependent cell proliferation and induction of apoptosis^[1]. In Vivo: AMG 337 (0-30 mg/kg; p.o.; daily, for 28 d) inhibits MET signaling in tumor xenografts and inhibits tumor growth in MET-dependent tumor xenograft models^[1].
AMG 337 (0-3 mg/kg; p.o.; once, for 3 or 24 h) is associated with increased necrosis in the MET-dependent SNU-620 tumor xenograft model^[1].
