- ABT-888 is a potent, orally bioavailable PARP-1/-2 inhibitor shown to potentiate DNA damaging agents. The ability to potentiate temozolomide (TMZ) and develop a biological marker for PARP inhibition was evaluated in vivo. Veliparib, also known as ABT-888, is a potent inhibitor of PARP-1 and PARP-2, with Ki values of 5.2 nM and 2.9 nM, respectively. It was demonstrated to have good oral bioavailability, to cross the blood-brain barrier well, to have modest antitumor activity alone, and to potentiate temozolomide, platinums, cyclophosphamide, and radiation in syngeneic and xenograft tumor models.

A phase 1 clinical study demonstrated that the combination of veliparib with metronomic cyclophosphamide was well tolerated and showed promising activity in a subset of patients with refractory solid tumors and lymphomas and with BRCA mutations.

Pressure-induced myogenic tone was potentiated while endothelium-dependent relaxation was reduced in diabetic mice compared with control mice. PARP-1 inhibitors INO-1001 and veliparib significantly reduced the potentiation of myogenic tone, improved endothelium-dependent relaxation, restored endothelial NO synthase phosphorylation and cGMP, and reduced cleaved PARP-1. PARP-1 inhibitors may be used to overcome diabetic microvascular dysfunction. Choi S.K., et al.
