描述 | The overexpression and activation of the Met receptor and its ligand HGF (hepatocyte growth factor) are associated with a wide variety of human malignancies. Meanwhile, it is found that VEGFRs can cooperate with Met to induce tumor invasion and vascularization. Foretinib is a multiple RTKs inhibitor with IC50 values of 0.4, 0.9/2.8 and 3nM for Met, VEGFR2/3 and Ron, less potent to Tie-2, Flt-3, PDGFRα, KIT, VEGFR1, PDGFRβ with IC50 values of 1.1nM, 3.6nM, 3.6nM, 6.7nM, 6.8nM and 9.6nM, with almost no inhibition of FGFR1 or EGFR (measured by in vitro kinase assay). Potent inhibition of p-Met by Foretinib with IC50 values of 23 and 21nM in PC-3 and B16F10 cells, as well as the suppression of p-ERK and p-VEGFR2 induced by VEGF with IC50 of 16nM in HUVECs can be observed, suggesting the cellular RTKs inhibition. Foretinib can block HGF-induced migration with IC50 value of 44nM, as well as inhibit the anchorage-independent tumor cell colony growth of B16F10 cells with IC50 of 40nM. A further study on Inhibition of endothelial tubule formation and migration by Foretinib showed that Foretinib at concentration of 5nM or higher can both inhibit VEGF-induced tubule formation and block VEGF- or HGF-stimulated migration of HMVEC-L cells. Once daily oral administration of Foretinib at dose of 30 and 100mg/kg reduced lung surface tumor burden by 50% and 58%, respectively, in mice intravenously implanted B16F10 cells. Similarly, Foretinib at dose of 30 and 100mg/kg resulted in tumor growth inhibition of 64% and 87%, respectively, in mice bearing B16F10 solid tumors[1]. | ||
作用机制 | Foretinib is an ATP-competitive inhibitor of HGFR and VEGFR.[1] |
