MPTP (1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine) is a neurotoxin, which can damage dopaminergic neurons. It causes symptoms resembling those observed in patients suffering from Parkinson's disease, and hence this toxin is widely used in studies on animal models of this disorder. Mutagenicity of MPTP was also reported by some authors, but results obtained by others suggested that this compound is not mutagenic. Interestingly, those contrasting results were based on the same assay (the Ames test). Therefore, we aimed to test MPTP mutagenicity by employing a recently developed Vibrio harveyi assay, which was demonstrated previously to be more sensitive than the Ames test, at least for some mutagens. We found that MPTP showed a significant mutagenic activity. Moreover, MPTP mutagenicity was attenuated by methylxanthines, compounds that are known to form complexes with aromatic mutagens.
