MET/PDGFRA-IN-1 (compound 8c) is a MET and PDGFRA protein inhibitor ( IC 50 : 36 μM for MET). MET/PDGFRA-IN-1 inhibits MET phosphorylation and induces cell apoptosis. MET/PDGFRA-IN-1 inhibits proliferation of MET-positive cells (IC 50 s: 15.3, 19.0, 22.0, 25.6, 21.0, 31.5 μM for AsPc-1, EBC-1, MKN-45, Mia-Paca-2, HT-29, K562 cells respectively).
