Glycine
|
Glycine (2-Aminoacetic acid, Aminoacetic acid, Glycocoll) is a non-essential, non-polar, non-optical, glucogenic amino acid that is primarily found in gelatin and silk fibroin. It is involved in the body's production of DNA, phospholipids and collagen, and in release of energy.

QNZ46
|
QNZ46 is a NR2C/NR2D-selective NMDA receptor non-competitive antagonist (IC50 values are 3, 6, 229, and >300, >300 μM for NR2D, NR2C, NR2A, NR2B, and GluR1, respectively). IC50 value: 3 μM (for NR2D), 6 μM (for NR2C), 229 μM (for NR2D NR2A)Target: NR2D, NR2C, NR2Ain vitro: QNZ46 is a noncompetitive inhibitor of GluN2C/D containing NMDA receptors. KD and IC50 values for binding and inhibition of GluN1/Glun2D receptors by QNZ46 are 4.9 and 3.9 μM, respectively. QNZ46 does not compete for binding of glutamate or glycine, but QNZ46 receptor binding requires the binding of glutamate to the GluN2 subunit.

L-Glutamic acid monosodium salt
|
L-Glutamic acid monosodium salt is the sodium salt of glutamic acid, found naturally in tomatoes, cheese and other foods. This compound acts as an excitatory transmitter and an agonist at all subtypes of glutamate receptors (metabotropic, kainate, NMDA, and AMPA). It shows a direct activating effect on the release of DA from dopaminergic terminals.
