In vitro
EMD 1214063 inhibits HGF-induced c-Met phosphorylation in A549 cells with IC50 of 6 nM. Treatment with EMD 1214063 induces a marked reduction of c-Met–constitutive phosphorylation in EBC-1 cells with IC50 of 9 nM. EMD 1214063 effectively blocka phosphorylation of the major downstream effectors of the c-Met enzyme, such as Grb2, Gab1, Sos, PLCγ, and phosphoinositide 3-kinase, in EBC-1, MKN-45, and Hs746T cells in the range of 1 to 10 nM. EMD 1214063 considerably inhibits the viability of MKN-45 cells with IC50 of less than 1 nM. Treatment with EMD 1214063 (as low as 0.1 nM) inhibits HGF-induced NCI-H441 cell migration, whereas concentrations of 100 nM to 1 μM almost completely prevents it.
In vivo
EMD 1214063 treatment, at doses of 10 mg/kg or more, results in more than 90% inhibition of c-Met phosphorylation in Hs746T xenograft tumor for a period of at least 72 hours. EMD 1214063 induces more than 50% reduction of cyclin D1 expression, which persists after 96 hours upon treatment with doses of 100 mg/kg. A transient induction of p27 and cleaved caspase-3 are also observed upon treatment with EMD 1214063. EMD 1214063 (15 mg/kg, daily) treatment induces complete regression of gastric carcinoma xenografts Hs746T, in which c-Met is amplified, overexpressed, and activated in a ligand-independent fashion.
