Effects of endogenous neurotoxin quinolinic acid on reactive oxygen species production by Fenton reaction catalyzed by iron or copper.

Journal of organometallic chemistry

Kubicova L, Hadacek F, Weckwerth W, Chobot V.
PMID: 25892824
J Organomet Chem. 2015 Apr 15;782:111-115. doi: 10.1016/j.jorganchem.2015.01.030.

The tryptophan metabolite, quinolinic (2,3-pyridinedicarboxylic) acid, is known as an endogenous neurotoxin. Quinolinic acid can form coordination complexes with iron or copper. The effects of quinolinic acid on reactive oxygen species production in the presence of iron or copper...

Frontiers in cellular neuroscience

Repetto IE, Monti R, Tropiano M, Tomasi S, Arbini A, Andrade-Moraes CH, Lent R, Vercelli A.
PMID: 27547177
Front Cell Neurosci. 2016 Aug 05;10:190. doi: 10.3389/fncel.2016.00190. eCollection 2016.

One major aim in quantitative and translational neuroscience is to achieve a precise and fast neuronal counting method to work on high throughput scale to obtain reliable results. Here, we tested the isotropic fractionator (IF) method for evaluating neuronal...

Isoprenoid pathway dysfunction in chronic fatigue syndrome.

Kurup RK, Kurup PA.
PMID: 26983655
Acta Neuropsychiatr. 2003 Oct;15(5):266-73. doi: 10.1034/j.1601-5215.2003.00045.x.

BACKGROUND AND AIMS: The isoprenoid pathway was assessed in 15 patients with chronic fatigue syndrome (CFS). The pathway was also assessed in individuals with differing hemispheric dominance to assess whether hemispheric dominance has any correlation with these disease states.METHODS:...

This article has been retracted at the request of the Editor-in-Chief as it contains inappropriately manipulated images in Figure 7B. As such this article represents a...

Inhibitory effect of some tropical green leafy vegetables on key enzymes linked to Alzheimer's disease and some pro-oxidant induced lipid peroxidation in rats' brain.

Journal of food science and technology

Oboh G, Akinyemi AJ, Ademiluyi AO, Bello FO.
PMID: 24803694
J Food Sci Technol. 2014 May;51(5):884-91. doi: 10.1007/s13197-011-0572-0. Epub 2011 Nov 04.

This study sought to investigate the inhibitory effect of some commonly consumed Nigerian green leafy vegetables (raw and blanched) on acetylcholinesterase and butyrylcholinesterase (key enzyme linked to Alzheimer's disease) activities and some pro-oxidants (FeSO4, Sodium nitroprusside and Quinolinic acid)...

The role of kynurenines in the production of neuronal death, and the neuroprotective effect of purines.

Journal of Alzheimer's disease : JAD

Stone TW, Behan WM, Jones PA, Darlington LG, Smith RA.
PMID: 12214038
J Alzheimers Dis. 2001 Aug;3(4):355-366. doi: 10.3233/jad-2001-3401.

The kynurenine metabolic pathway from tryptophan accounts for a large proportion of the metabolism of this amino acid in the brain. Although a major route for the generation of the essential co-factor nicotinamide adenine dinucleotide (NAD), two components of...

Photoinduced electron-transfer reactions with quinolinic and trimellitic acid imides: experiments and spin density calculations(1).

The Journal of organic chemistry

Griesbeck AG, Gudipati MS, Hirt J, Lex J, Oelgemoller M, Schmickler H, Schouren F.
PMID: 11031043
J Org Chem. 2000 Oct 20;65(21):7151-7. doi: 10.1021/jo001070r.

The regioselectivity of photoinduced electron-transfer (PET) reactions of unsymmetrical phthalimides is controlled by the spin density distribution of the intermediate radical anions. ROHF ab initio calculations were found to be most suitable for atomic spin density analysis. Intramolecular PET...

Synthesis of the neurotoxin quinolinic acid in apoptotic tissue from Suberites domuncula: cell biological, molecular biological, and chemical analyses.

Marine biotechnology (New York, N.Y.)

Schröder HC, Sudek S, Caro S, Rosa S, Perovic S, Steffen R, Müller IM, Müller WE.

Mar Biotechnol (NY). 2002 Dec;4(6):546-58. doi: 10.1007/s10126-002-0028-7.

Sessile marine animals, such as sponges, are prone to infection by prokaryotic as well as by eukaryotic attacking organisms. Using the sponge Suberites domuncula we document for the first time that in its apoptotic tissue a toxic compound is...

Quinolinic acid selectively induces apoptosis of human astrocytes: potential role in AIDS dementia complex.

Journal of neuroinflammation

Guillemin GJ, Wang L, Brew BJ.
PMID: 16042813
J Neuroinflammation. 2005 Jul 26;2:16. doi: 10.1186/1742-2094-2-16.

There is evidence that the kynurenine pathway (KP) and particularly one of its end products, quinolinic acid (QUIN) play a role in the pathogenesis of several major neuroinflammatory diseases, and more particularly AIDS dementia complex (ADC). We hypothesized that...

Animals with unilateral neurotoxic lesions in the striatum exhibit a stereotypical biased rotational behavior in response to dopamine agonists. We recently argued that the rotational test may be subject to sensitization effects of the drug. Accordingly, we proposed the...
