INO-1001 is a potent and selective inhibitor of PARP [1].

Poly(ADP-ribose) polymerase (PARP) is an enzyme involved in DNA repair and as a mediator of energy failure-induced cell death and NAD+ depletion [1].

In rodent and human fibroblast cell lines, INO-1001 significantly inhibited PARP activity. Treatment of 10 μM INO-1001 and a single dose of radiation caused significant radiosensitization of the three cells lines. While apoptosis was not increased, suggesting that INO-1001 increased radiation-induced cell killing through interfering with DNA repair mechanisms, increasing necrotic cell death [2].

In adult male mice subjected to moderate controlled cortical impact (CCI), injection intracerebral with INO-1001 (1.6 mg/kg) preserved brain NAD+ levels. In the Morris water maze, INO-1001 reduced the latency time to find the hidden platform and increased the time in the target quadrant [1]. In dogs underwent hypothermic cardiopulmonary bypass, reperfusion for 60 min after treatment with INO-1001 (1 mg/kg), INO-1001 significantly recovered left and right ventricular systolic function, increased coronary blood flow [3].
