Abstract: Numerous pathophysiological disorders involve some element of oxidative stress and bioenergetic deficit. Poly(ADP-ribose) polymerase-1 (PARP-1) inhibitors have been used recently as a promising new therapeutic strategy aimed at halting the bioenergetic decline associated with oxidative brain insults and other conditions. PARP-1 uses NAD+ as a substrate and is activated during stressful circumstances, mainly in the nucleus. PARP-1 inhibitors are well known for blocking the excessive consumption of NAD+, thereby preserving energy metabolism. But what is the role of mitochondria in this process? Recent investigations have begun to focus on whether mitochondrial function can also be preserved by PARP-1 inhibitors. This review will present some of the latest mechanistic evidence documenting the potential involvement of PARP-1 inhibitors in protecting mitochondrial function and preventing necrosis, apoptosis and mitochondrial calcium cycling.
