Crizotinib (PF-02341066)

Crizotinib (PF-02341066) is a potent inhibitor of c-Met and ALK with IC50 of 11 nM and 24 nM in cell-based assays, respectively. It is also a potent ROS1 inhibitor with Ki value less than 0.025 nM. Crizotinib induces autophagy through inhibition of the STAT3 pathway in multiple lung cancer cell lines.

Foretinib (GSK1363089)

Foretinib (GSK1363089, EXEL-2880, XL-880) is an ATP-competitive inhibitor of HGFR and VEGFR, mostly for Met and KDR with IC50 of 0.4 nM and 0.9 nM in cell-free assays. Less potent against Ron, Flt-1/3/4, Kit, PDGFRα/β and Tie-2, and little activity to FGFR1 and EGFR. Phase 2.

Capmatinib (INCB28060)

Capmatinib (INCB28060) is a novel, ATP-competitive inhibitor of c-MET with IC50 of 0.13 nM in a cell-free assay, inactive against RONβ, as well as EGFR and HER-3. Capmatinib (INCB28060) inhibits Wnt/β-catenin and EMT signaling pathways and induces apoptosis in diffuse gastric cancer positive for c-MET amplification. Phase 1.

Features:Inactive against RONβ, another member of the c-MET RTK family, as well as EGFR and HER-3 (members of the EGFR RTK family).

PHA-665752

PHA-665752 is a potent, selective and ATP-competitive c-Met inhibitor with IC50 of 9 nM in cell-free assays, >50-fold selectivity for c-Met than RTKs or STKs.

BMS-777607

BMS-777607 is a Met-related inhibitor for c-Met, Axl, Ron and Tyro3 with IC50 of 3.9 nM, 1.1 nM, 1.8 nM and 4.3 nM in cell-free assays, 40-fold more selective for Met-related targets versus Lck, VEGFR-2, and TrkA/B, and more than 500-fold greater selectivity versus all other receptor and non receptor kinases. Phase 1/2.

Features:A potent inhibitor of the Met family, and >40-fold selectivity vs. Lck, VEGFR2, and TrkA/B and >500-fold selective vs. other receptor and non-receptor kinases.

PF-04217903

PF-04217903 is a selective ATP-competitive c-Met inhibitor with IC50 of 4.8 nM in A549 cell line, susceptible to oncogenic mutations (no activity to Y1230C mutant). Phase 1.

SU11274

SU11274 (PKI-SU11274) is a selective Met inhibitor with IC50 of 10 nM in cell-free assays, no effects on PGDFRβ, EGFR or Tie2. SU11274 induces autophagy, apoptosis and cell cycle arrest.
