HIDE SMILES / InChI
FG-9041 (6,7-Dinitroquinoxaline-2,3-dion or DNQX) is an antagonist of non-NMDA glutamate (AMPA and kainate) receptor. FG-9041 is used in molecular biology to identify the properties of different types of channels. In addition, experiments in rats have shown that DNQX reduces electroconvulsive shock-induced impairment of learning-memory.

Sample Use Guides

Forty-eight adult Wistar-Kyoto (WKY) rats (an animal model for depressive behavior): DNQX (FG9041) (iv 2 mL 5 mg/kg DNQX through the tail veins of WKY rats )
Route of Administration: Intravenous
It was tested the effects of the quinoxaline derivative DNQX (FG9041) on the membrane potential of thalamic reticular nucleus (TRN) and ventrobasal (VB) neurons. DNQX (20 μM) produced a slow-onset, long-duration depolarization in all TRN neurons tested with average amplitude of 3.3 ± 1.1 mV. In contrast, DNQX (20 μM) did not alter the membrane potential (0.2 ± 0.5 mV, n = 6) or input resistance of VB neurons. Accordingly, in voltage-clamp recordings, DNQX (20 μM) evoked an inward current that averaged −14.3 ± 5.6 pA but not in VB neurons (1.3 ± 2.3 pA, n = 5, P > 0.1). At a lower concentration, DNQX (4 μM) produced a negligible depolarization (0.3 ± 0.3 mV, n = 5) in TRN neurons, but at higher concentrations, DNQX (100 μM) produced a larger depolarization that averaged 3.7 ± 1.6 mV.
