(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.

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 damage
Primary 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.David Schrmann from University of Base. Veliparib (ABT-888) purchased from Selleck.

| 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] |
