1-Methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) is N-demethylated by cytochromes P450 2D6, 1A2 and 3A4--implications for susceptibility to Parkinson's disease.


1-Methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) induces a Parkinson-like syndrome through biotransformation by monoamine oxidase B to the neurotoxic metabolite 1-methyl-4-phenylpyridine. Neuroprotection may be provided by parallel N-demethylation and N-oxidation pathways mediated by the microsomal cytochrome P450 and flavin monooxygenase systems… (More)
