Olaparib (4-(3-4-fluorophenyl) methyl-1(2H)-one), as known as AZD2281 or KU0059436, is a novel, selective and potent inhibitor of both poly adenosine diphosphate-ribose polymeras-1 (PARP-1) and poly adenosine diphosphate-ribose polymeras-2 (PARP-2). Having been successfully used in the treatment of tumors harboring BRCA mutations, olaparib strongly inhibits the growth of BRCA2-deficient mouse mannary tumor cell lines demonstrating cytotoxicity. In previous researches treating non-small cell lung carcinoma (NSCLC), olaparib increased the radiation sensitivity of NSCLC cells, grown as xenografts in nude mice, following radiation and increased vascular perfusion in Calu-6 tumors established in a dorsal window chamber (DWC) model.

Cell lines
Normal LCL cells ATM-null LCL cells
Preparation method
The solubility of this compound in DMSO is >10 mM. General tips for obtaining a higher concentration: Please warm the tube at 37 °C for 10 minutes and/or shake it in the ultrasonic bath for a while.Stock solution can be stored below -20°C for several months.
Reaction Conditions
10 μM, 1 hour
Applications
The sensitivity of cells to olaparib is mediated by absence of Ataxia Telangiectasia Mutated (ATM) activity. Immunoblot analysis revealed that in ATM wild-type LCLs, but not ATM null LCLs, phosphorylation of the ATM-dependent targets ATM S1981 and SMC1 S966 was induced in a dose-dependent manner by olaparib.
Animal models
Granta-519–engrafted NOD/SCID mice
Dosage form
Intraperitoneal injection, 50 mg/kg/d, for 14 days
Analysis of the percentage of human CD45 staining by FACS analysis revealed a significant reduction in the percentage of Granta-519 cells in the bone marrow and a trend toward reduced tumor cell load in the spleen of mice treated with olaparib compared with those receiving vehicle alone.
Other notes
Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal.
