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.
