1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) and 1-methyl-4-phenylpyridine (MPP/sup +/) cause rapid ATP depletion in isolated hepatocytes

Journal Article · · Biochem. Biophys. Res. Commun.; (United States)

1-Methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) and its oxidized metabolite 1-methyl-4-phenylpyridine (MPP/sup +/) produce a rapid depletion of intracellular ATP in isolated rat hepatocytes. This effect was dose-dependent and was consistently observed before the onset of toxicity. The monoamine oxidase inhibitor pargyline provide significant protection against MPTP-induced cell death and ATP loss, but had no effect with MPP/sup +/. Thus, ATP depletion may play a critical role in MPTP toxicity, possibly via the metabolic production of MPP/sup +/.
