2′-CH₃-MPTP, also known as 2′-methyl-MPTP, is a selective dopaminergic neurotoxin related to MPTP which is used in scientific research to lesion dopaminergic neurons.^[1]^[2] It is a considerably more potent dopaminergic neurotoxin than MPTP in mice but is less potent than MPTP in primates.^[3]^[1]^[4]^[5] MPTP and 2′-CH₃-MPTP produce a Parkinson's disease-like condition in animals.^[6]^[7]

2′-CH₃-MPTP is metabolized by monoamine oxidase A (MAO-A) and B (MAO-B) and this biotransformation is required for its dopaminergic neurotoxicity.^[1]^[8] Whereas the dopaminergic neurotoxicity of MPTP is completely prevented by the MAO-B inhibitor selegiline, complete prevention of 2′-CH₃-MPTP's dopaminergic neurotoxicity requires combined treatment with both selegiline and the MAO-A inhibitor clorgyline.^[8]^[9]

A close analogue of 2′-CH₃-MPTP is 2′-NH₂-MPTP, which, in contrast to 2′-CH₃-MPTP and MPTP, is a serotonergic and noradrenergic neurotoxin with no effect on dopaminergic neurons.^[10] Numerous other neurotoxic MPTP analogues have also been synthesized.^[8]

2′-CH₃-MPTP was first described in the scientific literature by 1986.^[4]
