(A) OVCAR-8 cells were exposed to the indicated concentrations of FdUrd along with vehicle, 3 μM ABT-888 or 300 nM AZD2281 for 24 h. Following washing, ABT-888 and AZD2281 were re-added to the plates initially exposed to these agents, and cells were cultured in the continued presence of ABT-888 and AZD2281 for 8 d until colonies formed. (B) OVCAR-8 cells were exposed continuously to the indicated agents for 8 d. (C) OVCAR-8 cells treated as in (A) except that the indicated concentrations of ABT-888 were used.

Number of foci detected using laser confocal microscopy and fluorescent Fluor 647 anti-H2A.X-phosphorylated (Ser139) antibody. Double-stranded breaks (red) are clearly augmented in cells incubated with 500 nmol/l of ABT-888 and 500 nmol/l of AZD-2281 compared with PBS and 1% dimethyl sulfoxide controls. Image analysis was performed using ImageJ and the ‘analyze particle’ function.

Logarithmic growth curves of human Burkitt lymphoma cells over 5 days with 500 nmol/l of ABT-888 and AZD-2281 in combination with 0 Gy (a), 4 Gy (b), 8 Gy (c), and 12 Gy (d) of external beam radiation. The maximal relative reduction was 65.5% of viable cells and occurred with AZD-2281 (500 nmol/l) on day 5. DMSO, dimethyl sulfoxide.

Colorimetric poly(ADP-ribose) polymerase (PARP) activity assay showing the relative activity of the PARP-1 enzyme in Raji lymphocyte tumor cells. Results show a highly significant difference in PARP activity in the controls [PBS and dimethyl sulfoxide (DMSO)] compared with 24 h incubation with 500 nmol/l of ABT-888 and 500 nmol/l of AZD-2281. A significant increase in PARP enzyme activity is shown in DMSO-incubated cells compared with PBS control.* P < 0.05.

in vivo suppression of PAR formation by the PARP inhibitor ABT-888 upon induction of DNA damagePrimary human lung fibroblast cells (MRC-5) were pre-treated with the indicated concentration of the PARP inhibitor ABT-888 for two hours. Oxidative DNA damage was induced by 500 µM H2O2 for 10 min and cellular PARP activity was measured by immuno-staining of poly(ADP)-ribose (PAR) (right panels). The in vivo effect of PARP inhibition was compared to cells without DNA damage induction and inhibitor (control) and H2O2-treated cells without inhibitor.
Average nuclear PAR staining intensities of more than 50 cells were statistically analysed by Kruskal-Wallis and the post-hoc Dunn’s Multiple Comparison tests (left panel). Asterisks indicate highly significant (p<1%) differences to H2O2-treated cells without PARP inhibitor. Thick horizontal bars mark medians and error bars the interquartile range.

Caption: 451 Lu is a melanoma cell line with high PARP expression that is resistant to temozolomide. Treatment with 25 µM ABT-888 greatly increased sensitivity to temozolomide compared to cells without ABT-888 treatment as measured by MTS assay.

|Description||Veliparib (ABT-888) 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. Phase 3.|
|Features||Increases the efficacy of common cancer therapies such as radiation and alkylating agents.|
ABT-888 is inactive to SIRT2 (>5 μM).  ABT-888 inhibits the PARP activity with EC50 of 2 nM in C41 cells.  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.  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. 
|In vivo||The oral bioavailability of ABT-888 is 56%-92% in mice, Sprague-Dawley rats, beagle dogs, and cynomolgus monkeys after oral administration.  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.  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. |

For best results, use promptly after mixing.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
