Peroxynitrite-mediated mitochondrial dysfunction.
Peroxynitrite anion (ONOO(-)) is a potent biological oxidant produced by the near diffusion-limited reaction of superoxide and nitric oxide. Peroxynitrite has been implicated in diverse forms of free radical-induced tissue injury. Experimental evidence showed that exogenous and endogenous peroxynitrite causes alterations of the structure and function of mitochondrial proteins, leading to mitochondrial dysfunction and cellular or organ injury. These data are discussed along with its physiopathological implications.
