Background:

Golvatinib is an inhibitor of c-Met and VEGFR-2 tyrosine kinase with IC50 values of 14nM and 16nM, respectively [1].

The small molecule compound, golvatinib, is a dual inhibitor of both c-Met and VEGFR-2. It is developed as a therapeutic reagent with more potent antitumor activity. Golvatinib inhibits the autophosphorylation of c-Met in MKN45 cells and inhibits the phosphorylation of VEGFR-2 in HUVECs with IC50 values of 14nM and 16nM, respectively. Golvatinib also inhibits the growth of various tumor cells including MKN45, EBC-1, Hs746T and SNU-5. Besides that, golvatinib effectively suppresses the growth induced by HGF or VEGF with IC50 values of 17nM and 84nM [1].

In mice models bearing xenograft tumor cell lines including MKN45, Hs746T, SNU-5 and EBC-1, treatment of golvatinib significantly inhibits the tumor growth. In mice xenograft model with VEGF-overexpressed human pancreatic cancer cell line KP-1 /VEGF, a single administration of E7050 reduces the VEGFR-2 phosphorylation and subsequently inhibits tumor growth through inhibiting VEGF /VEGFR-2 mediated tumor angiogenesis [1].
