产品描述:
Golvatinib is an orally bioavailable dual inhibitor of the receptor tyrosine kinases c-Met and VEGF receptor 2 (VEGFR2), which are involved in tumor progression.{41051} Golvatinib inhibits autophosphorylation of c-Met in MKN45 cells and phosphorylation of VEGFR2 in human umbilical vein endothelial cells (HUVECs; IC50s = 14 and 16 nM, respectively). It also inhibits proliferation of a variety of cancer cell lines and of HUVECs stimulated with hepatocyte growth factor (HGF) and VEGF but not bFGF (IC50s = 17, 84, and >1,000 nM for HGF-, VEGF-, and bFGF-stimulated HUVECs, respectively). In nude mouse xenograft models using MKN45, Hs746T, SNU-5, or EBC-1 cancer cells, golvatinib (25-200 mg/kg, daily) dose-dependently reduces tumor volume, and it increases survival in the model using MKN45 cells.
