Abstract: Oxidation of MPTP by monoamine oxidase (MAO), leading to the formation of reactive metabolites, is a critical step in the expression of the nigrostriatal toxicity of this molecule. A catalytic mechanism for the 2-electron oxidation of MPTP to MPDP+ and for the further 2-electron oxidation of MPDP+ to MPP+ is proposed, involving the formation of carbon-centered radical intermediates. These radical species appear to be involved in the mechanism-based inactivation of MAO by MPTP, possibly by generating 1,4-dihydr…
