AZD 2281 (Olaparib, KU-0059436) is a  novel, potent orally active PARP (poly ADP-ribose polymerase) inhibitorwith IC50 of 5 and 1 nM for PARP-1and PARP-2  respectively. AZD 2281 (Olaparib, KU-0059436) acts as an inhibitor of the enzyme Poly ADP ribose polymerase (PARP) and is one of the first PARP inhibitors.It induces cancer specific synthetic lethality in homologous recombination repair defective cells, including BRCA-deficient tumors. ......by AbMole BioScience

Olaparib, also known as AZD-2281 or KU-59436 , is a small molecule inhibitor of the nuclear enzyme poly(ADP-ribose) polymerase (PARP) with potential chemosensitizing, radiosensitizing, and antineoplastic activities. Olaparib selectively binds to and inhibits PARP, inhibiting PARP-mediated repair of single strand DNA breaks; PARP inhibition may enhance the cytotoxicity of DNA-damaging agents and may reverse tumor cell chemoresistance and radioresistance. PARP catalyzes post-translational ADP-ribosylation of nuclear proteins and can be activated by single-stranded DNA breaks. Olaparib was approved in 2014 for treating advanced ovarian cancer. ......by MedKoo Biosciences, Inc.

Protocol(Only for Reference)

Cell Experiment

Cell lines Normal LCL cells ATM-null LCL cells
Conditions 10 μM, 1 hour
Method 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 Experiment

Animal Models Granta-519–engrafted NOD/SCID mice
Dosage Form Intraperitoneal injection, 50 mg/kg/d, for 14 days
Applications 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.
