CNQX Chemical Properties,Uses,Production
Chemical Properties
Pale Yellow Solid
Uses
CNQX is a competitive, non-NMDA glutamate receptor antagonist (IC50s = 0.3 and 1.5 μM for AMPA and kainate receptors, respectively, versus IC50 = 25 μM for NMDA receptors). This compound has been used to specifically target AMPA and kainate receptor responses and thus differentiate from that of NMDA receptors.
Uses
CNQX disodium salt hydrate has been used as:
- as a competitive non-NMDA receptor antagonist and competitive AMPA/kainate receptor antagonist in neuronal cultures(110)
- as a glutamatergic blockers for measuring inhibitory postsynaptic currents in projection neurons(111)
- as a AMPA glutamate receptor antagonist prefrontal cortex neurons(112)
Uses
A potent, competitive kainate/quisqualate (non-NMDA) receptor antagonist. IC50 of tritiated ligands to rat cortical membranes by CNQX: AMPA, Kainate and CPP are 0.3mM, 1.5mM, and 25mM, respectively
Definition
ChEBI: 6-Cyano-7-nitroquinoxaline-2,3-dione is a quinoxaline derivative.
Biological Activity
Potent AMPA/kainate receptor antagonist. Also antagonist at glycine modulatory site on NMDA receptor complex.
Biochem/physiol Actions
Potent, competitive AMPA/kainate glutamate receptor antagonist.
