Biological Activity
DNQX (FG 9041) disodium salt, a quinoxaline derivative, is a selective, potent competitive non-NMDA glutamate receptor antagonist (IC50s = 0.5, 2 and 40 μM for AMPA, kainate and NMDA receptors, respectively)[1].
In Vitro
DNQX (FG 9041) disodium salt selectively depolarizes thalamic reticular nucleus (TRN) neurons[2].
In Vivo
DNQX (FG 9041), a specific AMPA receptor antagonist, given as either a 5 mg/kg or 10 mg/kg intraperitoneal dose or into the lateral cerebral ventricle (5 μl of 0.5 mg/ml) significantly diminishes phencyclidine (PCP) (40 mg/kg) and ketamine (80, 100, 120 mg/kg) hsp70 induction in the posterior cingulate and retrosplenial cortex[3].
