Golvatinib (E7050)是c-Met和VEGFR-2双重抑制剂,IC50分别为14 nM和16 nM,不抑制bFGF刺激的HUVEC生长(浓度高达1000 nM)。Golvatinib也能抑制多种肿瘤细胞的生长,包括MKN45\EBC-1\Hs746T和SNU-5.除此之外,golvatinib有效抑制HGF或VEGF诱导的生长,IC50值为17 nM和84 nM. 在MKN45\Hs746T\SUN-5和EBC-1肿瘤细胞系异种移植小鼠模型上,golvatinib显著抑制肿瘤的生长.在VEGF过表达的人胰腺癌细胞系KP-1 /VEGF异种移植小鼠模型中,E7050单一给药,可减少VEGFR-2的磷酸化,随后通过抑制VEGF/VEGFR-2介导的肿瘤血管生成从而抑制肿瘤的生长。
Information
Golvatinib (E7050) is a dualc-MetandVEGFR-2inhibitor with IC50 of 14 nM and 16 nM, does not inhibit bFGF-stimulated HUVEC growth (up to 1000 nM). Phase 1/2.
In vitro
In vitro studies indicate that E7050 potently inhibits phosphorylation of both c-Met and VEGFR-2. E7050 also potently represses the growth of both c-met amplified tumor cells and endothelial cells stimulated with either HGF or VEGF. E7050 circumvents resistance to all of the reversible, irreversible, and mutant-selective EGFR-TKIs induced by exogenous and/or endogenous HGF in EGFR mutant lung cancer cell lines, by blocking the Met/Gab1/PI3K/Akt pathway in vitro. E7050 also prevents the emergence of gefitinib-resistant HCC827 cells induced by continuous exposure to HGF.
In vivo
In vivo studies using E7050 shows inhibition of the phosphorylation of c-Met and VEGFR-2 in tumors, and strong inhibition of tumor growth and tumor angiogenesis in xenograft models. Treatment of some tumor lines containing c-met amplifications with high doses of E7050 (50–200 mg/kg) induces tumor regression and disappearance. In a peritoneal dissemination model, E7050 shows an antitumor effect against peritoneal tumors as well as a significant prolongation of lifespan in treated mice. In another xenograft model research, tumors produced by HGF-transfected Ma-1 (Ma-1/HGF) cells are more angiogenic than vector control tumors and shows resistance to ZD1839. E7050 alone inhibits angiogenesis and retards growth of Ma-1/HGF tumors. E7050 combined with ZD1839 induces marked regression of tumor growth.
