Quinolinic acid-d3
Based on 2 publication(s) in Google Scholar
Quinolinic acid-d3 is the deuterium labeled Quinolinic acid. Quinolinic acid, an endogenous metabolite of tryptophan, is a N-methyl-D-aspartate receptor (NMDA receptor) agonist. Quinolinic acid increases glutamate efflux, induces the generation of ROS, activates nitric oxide synthase, produces excessive NO, leading to calcium ion influx and neuronal apoptosis.

NMDA Receptor |
Stable heavy isotopes of hydrogen, carbon, and other elements have been incorporated into drug molecules, largely as tracers for quantitation during the drug development process. Deuteration has gained attention because of its potential to affect the pharmacokinetic and metabolic profiles of drugs[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
1. This compound can be used as a tracer
2. This compound can be used as an internal standard for quantitative analysis by NMR, GC-MS, or LC-MS.
