Product Overview
INO-1001 is a potent and selective inhibitor of PARP. 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. 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. 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. 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.
