描述:

Axitinib是一种多靶点抑制剂,作用于VEGFR-1, VEGFR-2,VEGFR-3,PDGFR-β和c-KIT时,其IC50分别为0.1 nM, 0.2 nM, 0.1-0.3 nM, 1.6 nM和1.7 nM。Axitinib是受体激酶抑制剂,作用于VEGFR-1, VEGFR-2,VEGFR-3, PDGFR-β和c-KIT时IC50分别为0.1 , 0.2, 0.1-0.3, 1.6 和1.7 nM 。Axitinib可以阻断VEGFR的自磷酸化作用,VEGF调节的内皮细胞活力,微管形成,及下游信号。Axitinib抑制多种细胞系的增殖,如作用于IGR-N91, IGR-NB8, SH-SY5Y ,无VEGF刺激的HUVEC时IC50分别为>1000 nM, 849 nM, 274 nM和573 nM。

溶解性:DMSO :9.7 mg/mL (25 mM)

体外研究:

Axitinib could block the cellular autophosphorylation of VEGFR and VEGF-mediated endothelial cell viability, tube formation, and downstream signaling. Axitinib inhibits the proliferation of variable cell lines with IC50 of >10,000 nM (IGR-N91), 849 nM (IGR-NB8), 274 nM (SH-SY5Y) and 573 nM (non-VEGF stimulated HUVEC).

体内研究:Axitinib exhibits primary inhibition to orthotopically transplanted models such as M24met (melanoma), HCT-116 (colorectal cancer), and SN12C (renal cell carcinoma). Axitinib delays the tumor growth with 11.4 days compared to the controls (p.o. 30 mg/kg) and decreases the Mean Vessels Density (MVD) to 21, compared to 49 in controls, in IGR-N91 ?ank xenografts. Axitinib significantly inhibits growth and disrupts tumor microvasculature in BT474 breast cancer model at 10-100 mg/kg. Axitinib has shown single-agent activity in variable tumors, including renal cell carcinoma, thyroid cancer, non-small cell lung cancer, and melanoma.
