Foretinib (GSK1363089)是一种ATP竞争性的HGFR和VEGFR抑制剂,作用于Met和KDR作用最强,IC50分别为0.4 nM和0.9 nM,对Ron, Flt-1/3/4, Kit, PDGFRα/β和Tie-2作用效果稍弱,对FGFR1和EGFR几乎没有抑制活性。An ATP-competitive inhibitor of tyrosine kinases including Flt-1, Flt-4, Met, and Ron.
Information
Foretinib (GSK1363089, EXEL-2880, XL-880, GSK089) is an ATP-competitive inhibitor of HGFR and VEGFR, mostly forMet (c-Met)andKDRwithIC50of 0.4 nM and 0.9 nM in cell-free assays. Less potent against Ron, Flt-1/3/4, Kit (c-Kit), PDGFRα/β and Tie-2, and litt
In vitro
XL880 inhibits HGF receptor family tyrosine kinases with IC50 values of 0.4 nM for Met and 3 nM for Ron. XL880 also inhibits KDR, Flt-1, and Flt-4 with IC50 values of 0.9 nM, 6.8 nM and 2.8 nM, respectively. XL880 inhibits colony growth of B16F10, A549 and HT29 cells with IC50 of 40 nM, 29 nM and 165 nM, respectively. A recent study indicates XL880 affects cell growth differently in gastric cancer cell lines MKN-45 and KATO-III. XL880 inhibits phosphorylation of MET and downstream signaling molecules in MKN-45 cells, while targets GFGR2 in KATO-III cells.
In vivo
A single 100 mg/kg oral gavage dose of XL880 results in substantial inhibition of phosphorylation of B16F10 tumor Met and ligand (e.g., HGFor VEGF)-induced receptor phosphorylation of Met in liver and Flk-1/KDR in lung, which both persisted through 24 hours. Treatment with XL880 (30-100 mg/kg, once daily, oral gavage) results in reduction in tumor burden. The lung surface tumor burden is reduced by 50% and 58% following treatment with 30 and 100 mg/kg XL880, respectively. XL880 treatment of mice bearing B16F10 solid tumors also results in dose-dependent tumor growth inhibition of 64% and 87% at 30 and 100 mg/kg, respectively. For both studies, administration of XL880 is well tolerated with no significant body weight loss. XL880 is developed to target abnormal signaling of HGF through Met and simultaneously target several receptors tyrosine kinase involved in tumor angiogenesis. XL880 caused tumor hemorrhage and necrosis in human xenografts within 2 to 4 hours, and maximal tumornecrosis is observed at 96 hours (after five daily doses), resulting in complete regression.
