Applications · 5 items

DescriptionL-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.

UsesAn amino acid that is able to function as an agonist at multiple excitatory amino acid receptor substrates in the central nervous system. It also has high affinity for the kainate, AMPA and the metabotropic receptors. Inhibits the Ca2+/Cl-dependent glutamic acid uptake system in brain synaptic plasma membrane preparations.

UsesQuisqualic acid has been used to test ligand-gated receptors in spiral ganglion neurons.

UsesQuisqualic acid is used to differentiate between mGluR-1 and mGluR-4. L-Quisqualic acid is an activator of GluR.

General DescriptionQuisqualate/ Quisqualic acid is obtained from the fruits and seeds of Quisqualis chinensis. It is an agonist at two subsets of excitatory amino acid receptors metabotropic receptors that indirectly mediate calcium mobilization from intracellular stores and, ionotropic receptors that directly control membrane channels. L-quisqualic acid is an agonist of the neurotransmitter L-glutamate.
