CAS Registry #: 912444-00-9
Formula: C13H16N4O
ABT-888 (Veliparib) is a potent inhibitor of both PARP-1 and PARP-2. In the MX-1 breast xenograft model (BRCA1 deletion and BRCA2 mutation), ABT-888 potentiated cisplatin, carboplatin, and cyclophosphamide, causing regression of established tumors, whereas with comparable doses of cytotoxic agents alone, only modest tumor inhibition was exhibited.
