Olaparib

SKU: orb1224047

Description

A potent, specific, and orally active PARP inhibitor with IC50 of 5 and 1 nM for PARP1 and PARP2, respectively; displays 300-fold selectivity over tankyrase (TNKS-1 IC50=1.5 uM); shows standalone activity against BRCA1-deficient breast cancer cell lines; regresses autochthonous Brca2/p53-mutant mammary tumors in vivo and delays tumor relapse in combination with carboplatin.Ovarian Cancer Approved(In Vitro):Olaparib (AZD2281) is a single digit nanomolar inhibitor of both PARP-1 and PARP-2 that shows standalone activity against BRCA1-deficient breast cancer cell lines. Olaparib is applied to SW620 cell lysates, and identified the IC50 for PARP-1 inhibition to be around 6 nM and the total ablation of PARP-1 activity to be at concentrations of 30 100 nM.(In Vivo):Animals bearing SW620 xenografted tumors are treated with Olaparib (10 mg/kg, p.o.) in combination with NSC 362856 (TMZ) (50 mg/kg, p.o.) once daily for 5 consecutive days, after which the tumors are left to grow out. Olaparib increases vascular perfusion in Calu-6 tumors established in a DWC model. Administration of olaparib(50 mg/kg, p.o.) as a single agent (top panel) or in combination with radiation (bottom panel) results in an increase in fluorescence intensity in the Calu-6 tumors.
