It has been shown that molecular hydrogen (H(2)) acts as a therapeutic antioxidant and suppresses brain injury by buffering the effects of oxidative stress. Chronic oxidative stress causes neurodegenerative diseases such as Parkinson's disease (PD). Here, we ...

Hydroxylated derivatives of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP), a nigrostriatal neurotoxin in humans and primates, noncompetitively inhibited dihydropteridine reductase from human liver and rat striatal synaptosomes in vitro at micromolar con...

C57 black mice were injected repeatedly with maximal tolerated doses of 2 chemical analogues of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP); 4-phenylpyridine and 4-phenyl-1,2,3,6-tetrahydropyridine. Although both compounds were clearly acutely toxic t...

We found that both MPTP and its metabolite MPP+ decrease dopamine and increase acetylcholine content of mouse neostriatum when administered intracerebroventricularly (ICV). These observations support the notion that MPP+ may be the active neurotoxin formed in...

Parkinson's Disease (PD) is marked by prominent motor symptoms that reflect striatal dopamine insufficiency. However, non-motor symptoms, including depression, are common in PD. It has been suggested that these changes reflect pathological involvement of non-...

The kinetics of the interactions of MPTP and its N-des-methyl-derivative (PTP) have been studied. Both were mechanism-based inhibitors as well as substrates for the enzyme. Analysis of the reaction progress-curves for the formation of the corresponding dihydr...
