VEGFR2 Kinase Inhibitor III is a cell-permeable ATP-competitive inhibitor of Flk-1 (VEGFR2/KDR, kinase insert domain receptor), which is the major growth factor for vascular endothelial cells. This receptor is a type III tyrosine kinase receptor that functions as the main mediator of VEGF-induced endothelial proliferation, survival, and migration. Studies suggest that VEGFR2 Kinase Inhibitor III also inhibits a variety of other receptors such as Met, Flt-3/Flk-2 (FLT-3 receptor tyrosine kinases), Ret, c-Kit, PDGFR, c-Abl and Arg (ABL), and ALK. In addition, VEGFR2 kinase inhibitor III regulates the signaling pathways used by oncogenic RET-transfected cells by regulating the extracellular signal regulated kinase (ERK) and JNK pathways. |
