Description

ABT-888 dihydrochloride, also known asVeliparib, is a potent and selective Poly (ADP-Ribose) Polymerase (PARP) Inhibitor. ABT-888 dihydrochloride enhances apoptosis and autophagy in response to treatments that cause DNA breaks, including radiation and DNA alkylation. ABT-888 dihydrochloride is an orally bioavailable inhibitor of PARP1 and PARP2 (Kis = 5.2 and 2.9 nM, respectively).

How to use

In Vitro:

ABT-888 dihydrochloride is inactive to SIRT2 (>5 μM). ABT-888 dihydrochloride inhibits the PARP activity with EC50 of 2 nM in C41 cells. ABT-888 dihydrochloride can decrease the PAR levels in both irradiated and nonirradiated H460 cells. ABT-888 dihydrochloride reduces clonogenic survival and inhibits DNA repair by PARP-1 inhibition in H460 cells. ABT-888 dihydrochloride increases apoptosis and autophagy in H460 cells when combination with radiation. ABT-888 dihydrochloride inhibits PARP activity in H1299, DU145 and 22RV1 cells and the inhibition is independent of p53 function. ABT-888 dihydrochloride (10 μM) suppresses the surviving fraction (SF) by 43% in the clonogenic H1299 cells. ABT-888 dihydrochloride shows effective radiosensitivity in oxic H1299 cells. ABT-888 dihydrochloride can attenuate the SF of hypoxic-irradiated cells including H1299, DU145 and 22RV1.

In Vivo:

The oral bioavailability of ABT-888 dihydrochloride is 56%-92% in mice, SD rats, beagle dogs, and cynomolgus monkeys after oral administration. ABT-888 dihydrochloride (25 mg/kg, i.p.) can improve tumor growth delay in a NCI-H460 xenograft model. Combination with radiation, veliparib decreases the tumor vessel formation. ABT-888 dihydrochloride 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 can be maintained over time.
