Brief Description

AMG-208 is a potent small molecular c-Met inhibitor with an IC50 of 9.3 nM.
IC50 value: 9.3 nM
Target: c-Met
in vitro: AMG-208 shows the potent inhibition of kinase c-Met activity with IC50 of 9 nM in a cell-free assay. Besides, AMG-208 treatment also leads to the inhibition of HGF-mediated c-Met phosphorylation in PC3 cells with IC50 of 46 nM [1]. Pre-incubation of AMG-208 with human liver microsomes for 30 minutes shows a potent time-dependent inhibition for CYP3A4 metabolic activity with IC50 of 4.1 μM, which is an eightfold decrease relative to the IC50 (32 μM) without preincubation [2]. AMG-208 is identified to be a c-MET and RON dual selective inhibitor [3].
in vivo: In male Sprague?Dawley rats, AMG-208 (0.5 mg/kg i.v.) shows a high bioavailability with Cl of 0.37 L/h/kg, Vss of 0.38 L/kg and T1/2 of 1 hour, while AMG-208 (2 mg/kg i.v.) shows a bioavailability with AUC0→∞ of 2517 ng·h/mL and F of 43%, respectively [1].
