MPP+ iodide, a toxic metabolite of the neurotoxin MPTP, causes symptom of Parkinsons disease in animal models by selectively destroying dopaminergic neurons in substantia nigra. MPP+ iodide is taken up by the dopamine transporter into dopaminergic neurons where it exerts its neurotoxic action on mitochondria by affecting complex I of the respiratory chain. MPP+ iodide is also a high affinity substrate for the serotonin transporter (SERT).

体外研究(In Vitro)
MPP+ (1-3 mM; 24 hours) remarkably decreases the viability of cells.MPP+ also inhibits the activity of nicotinamide adenosine dinucleotide (NADH)-linked respiration in mitochondrial preparations and impairs aerobic glycolysis, leading to the present belief that the inhibition of NADH-linked cell respiration may constitute the final molecular mechanism of MPP+ neurotoxicity. has not independently confirmed the accuracy of these methods. They are for reference only.
