Anwendungen & Verwendung
Beschreibung
L-Quisqualic acid is a natural analog of glutamate that acts as an agonist at AMPA-selective and metabotropic glutamate receptors (EC50s = 170, 10, 40, and 29 nM at GluR-A, mGluR1, mGluR3, and mGluR5, respectively), as well as the ionotropic kainate receptor (GRIK4; Ki = 6.43 nM). L-Quisqualic acid is used to study receptor dynamics and as an excitotoxin to selectively destroy neurons in the brain or spinal cord.
Verwenden
Quisqualic acid is used to differentiate between mGluR-1 and mGluR-4. L-Quisqualic acid is an activator of GluR.
