Biological Activity

ABT-888 (Veliparib) is a potent inhibitor of PARP-1 and PARP-2 with Ki values of 5.2nM and 2.9nM respectively. ABT-888 (Veliparib) inhibits PARPs, thereby inhibiting DNA repair and potentiating the cytotoxicity of DNA-damaging agents. ABT-888 (Veliparib) has good oral bioavailability, can cross the blood-brain barrier, and potentiates temozolomide, platinums, cyclophosphamide, and radiation in syngeneic and xenograft tumor models. This broad spectrum of chemopotentiation and radiopotentiation makes this compound an attractive candidate for clinical evaluation. Phase I study of PARP inhibitor ABT-888 in combination with topotecan in adults reveal that PARP inhibition can modulate the capacity to repair topoisomerase I-mediated DNA damage in the clinic.

Method Annexin V apoptosis assay
Cell Lines HCT-116 cells
Concentrations 0.5 μM
Incubation Time 4 h, 24 h or 48 h
Results Although little apoptosis was detected at the 24 h time point, a significant increase in apoptosis was observed at 48 h in the presence of SN38 or SN38 plus ABT-888 for both cell lines indicating that γH2AX preceded drug-inducedapoptosis.

Method PARP inhibition assay
Cell Lines HCT-116 cells
Concentrations 0.5 μM
Incubation Time 24 h
Results To demonstrate that this change in activity was not due to altered protein expression, western blot analysis was performed on samples treated for 1 h or 24 h with 0.5 μM ABT-888, 10 nM SN38 or combinations of these two
Cell Experiment
Cell lines C41 cells
Preparation method Cellular PARP Assay. C41 cells were treated with test compound for 30 min in a 96-well plate. PARP was activated by damaging DNA with 1 mM H2O2 for 10 min. Cells were washed with ice-cold PBS once and fixed with prechilled methanol/acetone (7:3) at -20 °C for 10 min. After air-drying, plates were rehydrated with PBS and blocked using 5% nonfat dry milk in PBS-tween (0.05%) (blocking solution) for 30 min at room temperature. Cells were incubated with anti-PAR antibody 10H (1:50) in blocking solution at room temperature for 60 min followed by washing with PBS-Tween20 5 times and incubation with goat antimouse fluorescein 5(6)-isothiocyanate (FITC)-coupled antibody (1:50) and 1 µg/mL 4′,6-diamidino-2-phenylindole (DAPI) in blocking solution at room temperature for 60 min. After washing with PBS-Tween20 5 times, analysis was performed using an fmax Fluorescence Microplate Reader set at the excitation and emission wavelength for FITC or the excitation and emission wavelength for DAPI. PARP activity (FITC signal) was normalized with cell numbers (DAPI).

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.
