实验参考方法
In Vitro

In vitro activity: Cediranib (also called AZD2171, an indole ether quinazoline derivative) is a highly potent VEGFR (KDR) inhibitor with IC50 of<1 nM and is>1000-fold more selective for VEGFR than PDGFR-α, CSF-1R and Flt3 in HUVEC cells. Inhibition of vascular endothelial growth factor-A (VEGF) signaling is a promising therapeutic approach that aims to stabilize the progression of solid malignancies by abrogating tumor-induced angiogenesis. By competing with adenosine triphosphate, cediranib binds to and inhibits all three vascular endothelial growth factor receptor (VEGF-1,-2,-3) tyrosine kinases, thereby blocking VEGF-signaling, angiogenesis, and tumor cell growth. Cediranib is being developed clinically as a once-daily oral therapy for the treatment of cancer.

Kinase Assay: Cediranib is dissolved in DMSO at a concentration of 10 mM. All enzyme assays are run at, or just below, the respective Km for ATP (0.2 - 30 μM). The inhibitory activity of Cediranib is determined against a range of recombinant tyrosine kinases [KDR, Flt-1, Flt-4, c-Kit, PDGFRα, PDGFRβ, CSF-1R, Flt-3, FGFR1, Src, Abl, epidermal growth factor receptor (EGFR), ErbB2, Aurora A, and Aurora B] using ELISA. Selectivity versus CDK2 and CDK4 serine/threonine kinases is examined using scintillation proximity assays with a retinoblastoma substrate and [γ-sup>33P]ATP. Activity of Cediranib is compared to MAPK kinase (MEK), which shows dual specificity. It is determined using a MAPK substrate, [γ-33P]ATP, and paper capture/scintillation counting.


Cell Assay: The proliferation of the HUVEC cell line is evaluated in the presence and absence of growth factors by measuring 3H-thymidine incorporation following a 4-day incubation period. Proliferation of MG63 osteosarcoma cells is induced by PDGF-AA, which selectively activates signaling of the PDGFRα homodimer. HUVEC and MG63 osteosarcoma cells are cultured in DMEM without phenol red containing 1% charcoal stripped FCS, 2 mM glutamine, and 1% nonessential amino acids for 24 hours. Cediranib or vehicle is added with PDGF-AA ligand (50 ng/mL) and plates incubated for another 72 hours. Cellular proliferation is determined using bromodeoxyuridine ELISA.

In VivoCediranib even suppresses tubule sprouting at subnanomolar concentrations and inhibits VEGF-induced angiogenesis. Cediranib causes hypertrophy in bone growth plate and prevents luteal development in ovary. These are physiological processes that are dependent upon angiogenesis. Cediranib shows broad spectrum activity in human tumor models at doses that are well tolerated. Besides, Cediranib causes regression of vascular tissues in human lung tumor xenografts.
