Cediranib maleate (AZD-2171 maleate) 是高选择性，有口服活性的 VEGFR2 抑制剂，对Flt1，KDR，Flt4，PDGFRα，PDGFRβ，c-Kit的 IC₅₀ 值分别为小于1， 小于3，5，5，36，2nM。

Cediranib maleate (AZD-2171 maleate) is a highly potent, orally available VEGFR inhibitor with IC 50 s of <1, <3, 5, 5, 36, 2 nM for Flt1, KDR, Flt4, PDGFRα, PDGFRβ, c-Kit, respectively.

In human umbilical vein endothelial cells, Cediranib inhibits VEGF-stimulated proliferation and KDR phosphorylation with IC50 values of 0.4 and 0.5 nM, respectively. In a fibroblast/endothelial cell coculture model of vessel sprouting, Cediranib also reduces vessel area, length, and branching at subnanomolar concentrations. has not independently confirmed the accuracy of these methods. They are for reference only.

Once-daily oral administration of Cediranib ablates experimental (VEGF-induced) angiogenesis and inhibits endochondral ossification in bone or corpora luteal development in ovary; physiologic processes that are highly dependent upon neovascularization. The growth of established human tumor xenografts (colon, lung, prostate, breast, and ovary) in athymic mice is inhibited dose-dependently by Cediranib, with chronic administration of 1.5 mg per kg per day producing statistically significant inhibition in all models. A histologic analysis of Calu-6 lung tumors treated with Cediranib reveals a reduction in microvessel density within 52 hours that becomes progressively greater with the duration of treatment. These changes are indicative of vascular regression within tumors. has not independently confirmed the accuracy of the
