Physical and Chemical Properties | Bioactive Cediranib maleate (AZD-2171 maleate) is a highly selective, orally active VEGFR2 inhibitor with IC50 values for Flt1,KDR,Flt4,PDGFRα,PDGFRβ,c-Kit less than 1, less than 3,5,5,36,2nM, respectively. |
In vitro study | In human umbilical vein endothelial cells, Cediranib inhibits VEGF-stimulated proliferation and KDR phosphorylation with IC 50 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. |
In vivo study | 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. |
