MitoTempo increases mitochondrial O2 dismutation and accumulates in the mitochondria. Apocynin, an NADPH oxidase inhibitor, attenuates ROS production as well as the resultant neuroinflammation and mitochondrial injury. N-acetylcysteine (NAC) is an aminothiol and synthetic precursor of intracellular cysteine and GSH, and is thought to be an important antioxidant.
