Olaparib

Off-white to beige powder. Soluble in DMSO (20mg/ml) or DMF (10mg/ml). Slightly soluble in ethanol (1mg/ml). Chemical. CAS: 763113-22-0. Formula: C24H23FN4O3. MW: 434.47. Synthetic. Olaparib is a cell-permable potent inhibitor of PARP1 and PARP2 (IC50=5 and 1nM, respectively) but is less effective against the PARP tankyrase-1 (IC50=1.5µM). Some poly(ADP-ribose) polymerases (PARPs) assist in the repair of single-strand DNA nicks, an important step in base excision repair (BER), counteracting against DNA alkylating agents. Olaparib is a anticancer and chemotherapeutic agent (especially in cancers with BRCA mutations) that can be used in cells and in animals, alone or in combination therapy with alkylating agents, to block BER and increase cancer cell death.
