Correlation of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine neurotoxicity with blood-brain barrier monoamine oxidase activity.
Systemic administration of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) causes parkinsonism in humans and subhuman primates, but not in rats and many other laboratory animals; mice are intermediate in their susceptibility. Since MPTP causes selective dopaminergic neurotoxicity when infused directly into rat substantia nigra, we hypothesized that systemic MPTP may be metabolized by monoam...
متن کاملOxidation and enzyme-activated irreversible inhibition of rat liver monoamine oxidase-B by 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP).
The compound 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP), which produces symptoms resembling Parkinson's disease in humans, acts both as a substrate and an enzyme-activated irreversible inhibitor of the B-form of monoamine oxidase from rat liver. Analysis of the inhibitory process showed the compound to be considerably more efficient as a substrate than as an irreversible inhibitor, wit...
متن کاملDeuterium isotope effect measurements on the interactions of the neurotoxin 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine with monoamine oxidase B.
Kinetic deuterium isotope effects for the noncompetitive, intermolecular monoamine oxidase B-catalyzed oxidation of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) to the corresponding 1-methyl-4-phenyl-2,3-dihydropyridinium species MPDP+ were found to be 3.55 on Vmax and 8.01 on Vmax/Km with MPTP-6,6-d2 as the deuterated substrate. Similar values were obtained with MPTP-2,2,6-d4 and MPTP-C...
متن کاملNeuro-rescue role of epicatechin-3-gallate on 1-methyl-4-phenyl- 1, 2, 3, 6 -tetrahydropyridine induced parkinsonic mice
Green tea polyphenols are known to possess various neuropharmacological properties. In the recent past, mice models using 1-methyl-4-phenyl-1, 2, 3, 6tetrahydropyridine (MPTP) have been widely used to study underlying mechanism of Parkinson’s disease. In this study, we examined the neurorescue properties of Epicatechin-3-gallate (ECG) against MPTP induced oxidative damage, neurotoxicity and beh...
متن کاملSynthesis and Antimicrobial Activity of Some 2-[(4-Substituted-Phenyl-3-Chloro-Azetidin-2-One)-5-(2'-Methylamino-4-Phenyl-1', 3'-Thiazolyl-]-1, 3,4-Thiadiazoles
A new 2-[(4-substituted-phenyl-3-chloroazetidin-2-one)-5-(2'-methylamino 4-phenyl-1', 3'-thiazolyl-]-1, 3, 4-thiadiazoles, 5(a-n) were synthesized from 2-substituted-benzylideneamino-5-[2'-methylamino-4'-phenyl-1',3'-thiazolyl]-1,3, 4-thiadiazole, 4(a-n) using 2-amino-4phenyl-1, 3-thiazole as a starting material. The synthesised compounds have been screened in vitro for their antimicrobial acti...
