AZD-2281, also known as Olaparib or KU-59436 , is a small molecule inhibitor of the nuclear enzyme poly(ADP-ribose) polymerase (PARP) with potential chemosensitizing, radiosensitizing, and antineoplastic activities. AZD-2281 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. AZD-2281 was approved in 2014 for treating advanced ovarian cancer.

How to use

In Vitro:

AZD-2281 (Olaparib) is a single digit nanomolar inhibitor of both PARP-1 and PARP-2 that shows standalone activity against BRCA1-deficient breast cancer cell lines. AZD-2281 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 AZD-2281 (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. AZD-2281 increases vascular perfusion in Calu-6 tumors established in a DWC model. Administration of AZD-2281(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.
