Vascularendothelialgrowth factor receptor 2 (VEGFR2, also known as KDR and FLK1) is a receptor tyrosine kinase that regulates angiogenesis, vascular development, and embryonic hematopoiesis in response to VEGF isoforms A, C, and D. VEGFR2 kinase inhibitor II is a reversible, cell-permeable inhibitor of VEGFR2's kinase activity (IC50 = 70 nM). It less potently inhibits the platelet-derived growth factor receptor β (PDGFRβ; IC50 = 920 nM) and related receptor and non-receptor tyrosine kinases. VEGFR2 kinase inhibitor II blocks the growth of human umbilical vein endothelialcells stimulated with either VEGF or PDGF (IC50s = 110 nM and 2 μM, respectively).
PF-00337210 is an orally available ATP-competitive inhibitor of the vascularendothelialgrowth factor receptor type 2 (VEGFR2), with potential anti-angiogenesis and antineoplastic activities. Upon administration, the VEGFR2 tyrosine kinase inhibitor PF-00337210 selectively binds to VEGFR2 and prevents its phosphorylation which may result in an inhibition of migration, proliferation and survival of endothelialcells, microvessel formation, the inhibition of tumor cell proliferation, and may eventually cause tumor cell death. VEGFR2, a receptor tyrosine kinase, is frequently overexpressed by a variety of tumor types.
Foretinib phosphate is an orally bioavailable small molecule with potential antineoplastic activity. MET VEGFR2 inhibitor GSK1363089 binds to and selectively inhibits hepatocyte growth factor (HGF) receptor c-MET and vascularendothelialgrowth factor receptor 2 (VEGFR2), which may result in the inhibition of tumor angiogenesis, tumor cell proliferation and metastasis. The proto-oncogene c-MET has been found to be over-expressed in a variety of cancers.
Apatinib, also known as Rivoceranib and YN-968D1, is an orally bioavailable, small-molecule receptor tyrosine kinase inhibitor with potential antiangiogenic and antineoplastic activities. The free-base form is also known as Rivoceranib. Apatinib selectively binds to and inhibits vascularendothelialgrowth factor receptor 2, which may inhibit VEGF-stimulated endothelialcell migration and proliferation and decrease tumor microvessel density. In addition, this agent mildly inhibits c-Kit and c-SRC tyrosine kinases.
