Inhibitor of poly(ADP-ribose) polymerase (PARP) (IC50 = 9.5 μM); displays mixed inhibition with respect to NAD+. Protective against ischemia-reperfusion induced ROS production, and subsequent mitochondrial and cell damage in rat heart. Anti-inflammatory in LPS-induced endotoxic mice in vivo; decreases NF-κB and AP-1 activation.
