Toxizit?t Focal injection of quinolinic acid into specific areas of the brain produces neuronal damage although sparing axons of passage. Similarities between the biochemical and morphological profiles of these lesions and human neuropathy seen in neurodegenerative diseases have led to the proposal that endogenous excitotoxins may play a role in such neurodegenerative disease states. Quinolinic acid is an intermediate in the kynurenine pathway of tryptophan metabolism and has been detected in the brains of several mammals including man. The neuroexcitatory action is thought to be mediated via interaction with the N-methyl-D-aspartate (NMDA) receptor of the glutamate family. No mechanism for quinolinic acid removal, nor for synaptic inactivation, has been found, and consequently accumulation of concentrations capa_x0002_ble of inducing neuronal degeneration and death may occur.

Verwenden

Quinolinic acid is an endogenous NMDA agonist. Quinolinic acid is a metabolite of tryptophan that acts as a putative NMDA receptor agonist. Quinolinic acid is an ?excitotoxic? metabolite and an agonist of N-methyl-D-aspartate receptors. properties of KYNA raise the possibility of a functional link between KYNA and QUIN in the brain which may be of relevance for an understanding of human neurodegenerative disorders. Quinolinic acid is a potent endogenous excitant at amino acid receptors in CNS.

Biosynthese

The 3-hydroxyanthranilic acid oxygenase (3-HAO) catalyzes the conversion of 3-hydroxyanthranilic acid (3-HA) acid to an unstable intermediate, aminocarboxymuconic semialdehyde, which then preferentially converts to QUIN by a nonenzymatic cyclisation. This intermediate compound can also produce picolinic acid instead of QUIN. Finally, QUIN is catabolized to NAD+ and carbon dioxide by the action of quinolinate phosphoribosyl transferase (QPRT). This enzyme has been identified in rat and human CNS tissue[1].

Hazard

A poison by skin contact. Moderately toxic by ingestion. A mild skin irritant.

Industrielle Verwendung

The use of quinolinic acid during flotation of hematite results in the adsorption of quinoline on hematite, allowing amine to selectively adsorb onto the hematite surface.

Biologische Aktivit?t

Endogenous NMDA agonist and transmitter candidate. May distinguish between NMDA receptor subtypes.

Sicherheitsprofil

A poison by skin contact. Moderately toxic by ingestion. Experimental reproductive effects. A mdd skinn irritant. When heated to decomposition it emits toxic vapors of NOx.
