Mechanism of Action

Targets/IC₅₀/Ki	PDGFRβ ^[1] (Cell-free assay) 1 nM PDGFRα ^[1] (Cell-free assay) 10 nM
In vitro	CP 673451 is a selective inhibitor of PDGFRα/β with IC50 of 10 nM/1 nM, exhibits >450-fold selectivity over other angiogenic receptors. In glioblastoma tumors, this compound (33 mg/kg) provides >50% inhibition of PDGFR-β receptor for 4 hours corresponding to an EC50 of 120 ng/mL in plasma at C_max. In a sponge angiogenesis model, this inhibitor inhibits 70% of PDGF-BB-stimulated angiogenesis at a dose of 3 mg/kg (q.d. ×5, p.o., corresponding to 5.5 ng/mL at C_max).^[1] This chemical decreases cell proliferation rate through mechanisms involving reduced phosphorylation of GSK-3α and GSK-3β. In both RD and RUCH2 cultures, it impairs rhabdosphere-forming capacity and cell differentiation, causes increased senescence. ^[2]
Kinase Assay	Kinase inhibition assay
Kinase Assay	A glutathione S-transferase-tagged kinase domain construct of the intracellular portion of the PDGFR-β (amino acids 693-1401, accession no. J03278) is expressed in Sf-9 cells (baculovirus expression system). Enzyme kinetics are determined by incubating the enzyme with increasing concentrations of ATP in phosphorylation buffer [50 mmol/L HEPES (pH 7.3), 125 mmol/L NaCl, 24 mmol/L MgCl₂ in Nunc Immuno MaxiSorp 96-well plates previously coated with 100 μL of 100 μg/mL poly-Glu-Tyr (4:1 ratio) diluted in PBS. After 10 minutes, the plates are washed (PBS, 0.1% Tween 20), incubated with anti-phosphotyrosine-horseradish peroxidase antibody, and diluted in PBS, 0.05% Tween 20, 3% BSA for 30 minutes at room temperature. The plates are washed as above and incubated with 3,3
In vivo	CP 673451 (once-daily p.o. ?0 days dosing routinely) inhibits tumor growth (ED50 < 33 mg/kg) in a number of human tumor xenografts grown s.c. in athymic mice, including H460 human lung carcinoma, Colo205 and LS174T human colon carcinomas, and U87MG human glioblastoma multiforme. ^[1] In RUCH2 xenograft-bearing mice, this compound reduces tumor growth and stromal cell infiltration. ^[2]

Frequently Asked Questions

Question 1:
I need to formulate it for animal studies via oral gavage, any suggestions?

Answer:
For oral gavage, it can be dissolved in 30% PEG 400+5% propylene glycol+1% Tween 80+ddH2O at 30 mg/ml as a suspension. When preparing the solution, please add PEG 400 and propylene glycol to the compound first. Sonicate or stir it, then add Tween 80, after they mixed well, then dilute with water.
