Biological Activity

Description Veliparib (ABT-888, NSC 737664) is a potent inhibitor of PARP1 and PARP2 with Ki of 5.2 nM and 2.9 nM in cell-free assays, respectively. It is inactive to SIRT2. Veliparib increases autophagy and apoptosis. Phase 3.
Targets
PARP2 [1]
(Cell-free assay)		 PARP1 [1]
(Cell-free assay)
2.9 nM(Ki) 5.2 nM(Ki)
In vitro

ABT-888 is inactive to SIRT2 (>5 μM). [1]

ABT-888 inhibits the PARP activity with EC50 of 2 nM in C41 cells. [2]

ABT-888 could decrease the PAR levels in both irradiated and nonirradiated H460 cells. ABT-888 also reduces clonogenic survival and inhibits DNA repair by PARP-1 inhibition in H460 cells. ABT-888 increases apoptosis and autophagy in H460 cells when combination with radiation. [3]

ABT-888 also inhibits PARP activity in H1299, DU145 and 22RV1 cells and the inhibition is independent of p53 function. ABT-888 (10 μM) suppresses the surviving fraction (SF) by 43% in the clonogenic H1299 cells. ABT-888 shows effective radiosensitivity in oxic H1299 cells. Furthermore, ABT-888 could attenuate the SF of hypoxic-irradiated cells including H1299, DU145 and 22RV1. [4]
In vivo

The oral bioavailability of ABT-888 is 56%-92% in mice, Sprague-Dawley rats, beagle dogs, and cynomolgus monkeys after oral administration. [1]

ABT-888 (25 mg/kg i.p.) could improve tumor growth delay in a NCI-H460 xenograft model with well tolerated. Combination with radiation, ABT-888 decreases the tumor vessel formation. [3]

ABT-888 reduces intratumor PAR levels by more than 95% at a dose of 3 and 12.5 mg/kg in A375 and Colo829 xenograft models and the suppression could be maintained over time. [4]
Features Increases the efficacy of common cancer therapies such as radiation and alkylating agents.

Protocol (from reference)

Kinase Assay:

[1]
  • In vitro PARP assays

    PARP assays are conducted in a buffer containing 50 mM Tris (pH 8.0), 1 mM DTT, 1.5 μM [3H]NAD+ (1.6 μCi/mmol), 200 nM biotinylated histone H1, 200 nM slDNA, and 1 nM PARP-1 or 4 nM PARP-2 enzyme. Reactions are terminated with 1.5 mM benzamide, transferred to streptavidin Flash plates, and counted using a TopCount microplate scintillation counter.
Animal Study:

[1]
  • Animal Models

    NCI-H460, H460, B16F10 and 9L xenografts in C57BL/6 mice

  • Dosages

    ~25 mg/kg

  • Administration

    Orally administered
