AZD-2461 is a potent PARP inhibitor, with IC₅₀s of 5 nM, 2 nM and 200 nM for PARP1, PARP2 and PARP3, respectively.

AZD-2461 is a potent PARP inhibitor, with IC₅₀s of 5 nM, 2 nM and 200 nM for PARP1, PARP2 and PARP3, respectively. AZD-2461 (500 nM) shows inhibitory activity against DNA single-strand break repair in human A459 cells. AZD-2461 cuases resistance and high P-gp expression levels in BRCA2-deficient mouse breast cancer line KB2P3.4^[1]. AZD-2461 is cytotoxic to BT-20 cells (5-50 μM), increases the proportions of S- and G2-phase BT-20 cells (5-20 μM), and weakly affects the progression of cell cycle in SKBr-3 cells (5-20 μM)^[2].

AZD-2461 (10 mg/kg, p.o.) enhances the antitumor activity of temozolomide in a mouse colorectal xenograft and exhibits low effect on mouse bone marrow cells. However, the increased bone marrow tolerability of AZD-2461 is not seen in rat models^[1]. AZD-2461 (0.5% v/w HPMC, p.o.) increases the survival of mice bearing KB1P tumors after short-term treatment, and long-term treatment is well tolerated, but can not lead to tumor eradication^[3].

BT-20 and SKBr-3 human primary breast cancer cell lines are used in the assay. SKBr-3 cells are cultivated in DMEM medium with 10% FCS and BT-20 in RPMI medium under an atmosphere containing 5% CO₂. Twenty four hours after plating (at 60-70% confluence), the cells are treated with the PARP-1 inhibitors NU1025, AZD-2461, iniparib, olaparib, and rucaparib at concentrations ranging from 50 to 200 μM, 5 to 50 μM, 5 to 50 μM, 1 to 10 μM, and 0.3 to 10 μM, respectively, for durations indicated in figures 1-7^[2].

Starting from 2 weeks after transplantation into mice, tumor size is monitored at least 3 times a week. All treatments are started when tumors reach a size of approximately 200 mm³. Olaparib (50 mg/kg intraperitoneally) and AZD-2461 (100 mg/kg per os) are given for 28 consecutive days, unless otherwise indicated. If tumors do not shrink below 50% of the initial volume, treatment is continued for another 28 days; otherwise, a new treatment cycle of 28 days is started when the relapsing tumor reaches a size of 100% of the original volume. AZD-2461 is diluted in 0.5% w/v hydroxypropyl methylcellulose in deionized water to a concentration of 10 mg/mL^[3].
