Brief Description

Olaparib (AZD2281, KU0059436) is a potent PARP inhibitor with IC50 of 5 and 1 nM for PARP-1and PARP-2, respectively.
IC50 Value: 5 nM(PARP-1); 1 nM(PARP-2)
Target: PARP
in vitro: Olaparib would act against BRCA1 or BRCA2 mutations. Olaparib is not sensitive to tankyrase-1 (IC50 >1 μM). Olaparib could ablate the PARP-1 activity at concentrations of 30-100 nM in SW620 cells. Olaparib is hypersensitive to BRCA1-deficient cell lines (MDA-MB-463 and HCC1937), compared with BRCA1- and BRCA2-proficient cell lines (Hs578T, MDA-MB-231, and T47D). Olaparib is strongly sensitive to KB2P cells due to suppression of base excision repair by PARP inhibition, which may result in the conversion of single-strand breaks to double-strand breaks during DNA replication, thus activating BRCA2-dependent recombination pathways.
in vivo: Olaparib shows great response to Brca1-/-; p53-/- mammary tumors (50 mg/kg i.p. per day), while no responses to HR-deficient Ecad-/-;p53-/- mammary tumors. Olaparib even does not show dose-limiting toxicity in tumor-bearing mice. Olaparib has been used to treat with BRCA mutated tumors, such as ovarian, breast and prostate cancers. Moreover, Olaparib shows selectively inhibition to ATM (Ataxia Telangiectasia Mutated)-deficient tumor cells, which indicates to be a potential agent for treating ATM mutant lymphoid tumors.
