Biological Activity

AZD7762 hydrochloride 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 SW620 and MDA-MB-231 cells line
Preparation method Potentiation Assays.
SW620 (5.5 × 103 per well) or MDA-MB-231 (5 × 103 per well) cells were seeded in 96-well plates and incubated overnight. Cells were dosed for 24 h with a 9-point titration of gemcitabine ranging from 0.01 to 100 nmol/L with or without a constant dose of AZD7762 (300 nmol/L). Control wells were dosed with vehicle alone (0.1% DMSO) or 300 nmol/L AZD7762. After 24 h, medium was removed and AZD7762 alone was added back to the wells treated previously with AZD7762 for an additional 24 h. Cells were then incubated in drug-free medium for an additional 72 h. The effect on cell proliferation was determined by 3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethophenyl)-2-(4-sulfophenyl)-2H-tetrazolium, inner salt assay as recommended by the supplier (Promega). The same experimental procedure was used for topotecan combinations (topoisomerase I inhibitor, analogue of camptothecin) except an 11-point titration of topotecan ranging from 0.1 nmol/L to 30 μmol/L was used. Net growth was calculated (AT120 - AT0 / predose) × 100 and plotted versus concentration of chemotherapy in the presence and absence of AZD7762. IC50 values were calculated by concentration-response fitting using four-variable logistical equations (Sigmoidal fit) within Origin Pro.

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.
