Biological Activity

AZD7762 is a potent ATP-competitive checkpoint kinase inhibitor with an IC50 of 5 and <10 nM for CHK1 and CHK2 respectively.AZD7762 has been profiled extensively in vitro andin vivo in combination with DNA-damaging agents and has been shown to potentiate response in several different settings where inhibition of checkpoint kinase results in the abrogation of DNA damage-induced cell cycle arrest.

Protocol
Cell Experiment
Cell lines H29 cells
Preparation method Checkpoint Abrogation Assay
HT29 cells (3 × 105) were seeded in 96-well plates and incubated overnight. Cells were treated for 2 h with camptothecin (topoisomerase I inhibitor; 0.07 μg/mL) to induce the G2 checkpoint. Cells were then treated for 20 h with vehicle (0.5% DMSO) or caffeine (4 mmol/L; positive control) plus nocodazole (1 μg/mL) or a 12-point titration of AZD7762 (12.5 μmol/L to 6 nmol/L) plus nocodazole. Nocodazole alone-treated cells with no camptothecin pretreatment were used to determine the maximum mitotic index. Cells were fixed with 3.7% formaldehyde for 1 h, permeabilized with PBS containing 0.05% Triton X, and incubated with anti-phH3 antibody for 1 h followed by Alexa Fluor 488 anti-rabbit (Molecular Probes) and Hoechst stain for 1 h. Mitotic index was determined on the ArrayScan and expressed as the percentage of cells undergoing mitosis. The EC50 was calculated by concentration-response curve fitting using three-variable logistical equations within XLfit (model 205) with the curve bottom constrained to 0 and the top constrained to 100 by nocodazole alone treatment.
Concentrations 6nM~12.5μM
Incubation time 20 h
Animal Experiment
Animal models athymic mice bearing established H460-DNp53 or SW620 tumors and rnu rats bearing established H460-DNp53 tumors
Formulation formulated in 11.3% hydroxyproplyl-β-cyclodextrin
Dosages 25mg/kg(mouse) and 10 or 20mg/kg (rat)
Administration i.v. injection via the tail vein
Conversion of different model animals based on BSA (Value based on data from FDA Draft Guidelines)
Species Mouse Rat Rabbit Guinea pig Hamster Dog
Weight (kg) 0.02 0.15 1.8 0.4 0.08 10
Body Surface Area (m2) 0.007 0.025 0.15 0.05 0.02 0.5
Km factor 3 6 12 8 5 20
Animal A (mg/kg) = Animal B (mg/kg) multiplied by  Animal B Km
Animal A Km

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.
