Chemical Properties
Pale Yellow Solid
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
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.
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.
