6,7-Dinitroquinoxaline-2,3-dione (DNQX) is a non-N-methyl-D-aspartate (non-NMDA) receptor complex antagonist. The compound may act to attenuate JNK3 activation and has been shown not to stimulate a robust long-term potentiation in hippocampul studies. 6,7-Dinitroquinoxaline-2,3-dione (DNQX) is an inhibitor of GluR.
