MPTP (1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine) is an organic compound. It is classified as a tetrahydropyridine . It is of interest as a precursor to the monoaminergic neurotoxin MPP + , which causes permanent symptoms of Parkinson's disease by destroying dopaminergic neurons in the substantia nigra of the brain .
1-Methyl-4-phenyl-1,2,3,6-tetrahydropyridine causes permanent symptoms of Parkinson's disease. (–)-Mitragynine is a naturally occurring tetrahydropyridine. 2,3,4,5-Tetrahydropyridine, a colorless liquid, is commercially available. It is an imine. Illustrating another isomer of tetrahydropyridine, 6-acetyl-2,3,4,5-tetrahydropyridine occurs ...

2′-NH 2-MPTP, also known as 2′-amino-MPTP, is a monoaminergic neurotoxin that was derived from MPTP and is used in scientific research to lesion brain monoaminergic systems in animals. [ 1 ] [ 2 ] Whereas MPTP is a selective dopaminergic neurotoxin , 2′-NH 2 -MPTP is a specific serotonergic and noradrenergic neurotoxin that does not ...
A close analogue of 2′-CH 3-MPTP is 2′-NH 2-MPTP, which, in contrast to 2′-CH 3-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′-CH 3-MPTP was first described in the scientific literature by 1986. [4]
A new study is illuminating how “forever chemicals” can alter our brain cells by impairing the genes that maintain healthy neurons, the cells of our nervous system.
Methylphenyltetrahydropyridine N-monooxygenase (EC 1.13.12.11) is an enzyme with systematic name 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine:oxygen N-oxidoreductase. [1] This enzyme catalyses the following chemical reaction
It is also the most-used fire retardant in the world, according to a 2022 report in the Associated Press. ... 14% fertiliser-type salts, 6% colouring agents and corrosion inhibitors. ...
