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 neurotoxin MPP +, which causes permanent symptoms of Parkinson's disease by destroying dopaminergic neurons in the substantia nigra of the brain. It has been used to study disease models ...

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 ...
6-Acetyl-2,3,4,5-tetrahydropyridine and 2-acetyl-1-pyrroline are usually formed by Maillard reactions during heating of food. Both compounds have odor thresholds below 0.06 ng/L. Structure and properties. 6-Acetyl-2,3,4,5-tetrahydropyridine is a substituted tetrahydropyridine and a cyclic imine as well as a ketone. The compound exists in a ...
The 3 substrates of this enzyme are succinyl-CoA, (S)-2,3,4,5-tetrahydropyridine-2,6-dicarboxylate, and H 2 O, whereas its two products are CoA and N-succinyl-L-2-amino-6-oxoheptanedioate. This enzyme belongs to the family of transferases , specifically those acyltransferases transferring groups other than aminoacyl groups.
Android Eclair. Android Eclair is a codename of the Android mobile operating system developed by Google, the fifth operating system for Android and the second major release of Android. Eclair spans the versions 2.0.x and 2.1. Unveiled on October 26, 2009, Android Eclair builds upon the significant changes made in Android 1.6 "Android Donut". [4]
The version history of the Android mobile operating system began with the public release of its first beta on November 5, 2007. The first commercial version, Android 1.0, was released on September 23, 2008. The operating system is developed by Google on a yearly cadence since at least 2011. [1] New major releases are announced at Google I/O in ...
1-Methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) is a widely used neurotoxin in Parkinson's disease research (Figure 4). In contrast to 6-OHDA, MPTP crosses the BBB which making the neurotoxin even more selective for dopaminergic neurons. Due to the ability to cross the blood-brain-barrier, MPTP is administered peripherally, subcutaneously.
