This non-NMDA receptor antagonist inhibits [3H]AMPA binding to quisqualate receptors at submicromolar concentrations. CNQX also selectively blocks the excitatory action of quisqualate and kainate on spinal neurons with little or no effect on that of NMDA.nThe concentrations that inhibit 50% of [3H]AMPA binding (IC50) for CNQX in dorsal horn neurons is 300 nM.
产品描述
AMPA/Kainate receptor antagonist
产品形式
The first widely used competitive AMPA receptor antagonists were quinoxalinediones (CNQX, DNQX, NBQX), which were highly selective over NMDA receptors but antagonized kainate receptors. CNQX is a potent, competitive AMPA/kainate receptor antagonist. It also acts as an antagonist at the NMDA receptor glycine site.
