BUY DNQX disodium salt
The first widely used competitive AMPA receptor antagonists were quinoxalinediones (CNQX, DNQX, NBQX), which were highly selective over NMDA receptors but antagonized kainate receptors. Surprisingly, association of AMPA receptors with TARP auxiliary subunits converts DNQX from an antagonist to a weak partial agonist. DNQX induces partial domain closure, consistent with the activity of a partial agonist.
DNQX interacts with residues primarily within domain D1 of the clamshell, thereby depriving the agonist of its initial contact sites with the open cleft of the binding pocket.
The concentrations that inhibit 50% of AMPA binding (IC50) for DNQX is 0.50 пїЅ 0.10 uM, and about one-fifth as effective at kainate binding sites, 2.0 пїЅ 0.1 uM in rat cortical membranes.
The IC50 of DNQX is 1 uM in a crystal structure of the GluR2 ligand binding core.
Alomone Labs is pleased to offer DNQX disodium salt (D-130).
