Application

NBQX disodium salt hydrate has been used:
  • in N-methyl-D-aspartate receptor (NMDAR) kinetic studies
  • as an α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptor antagonist for the electrophysiological studies cultured neurons
  • in the extracellular solution for current/voltage (I/V) relationship and rectification index experiments in excitatory postsynaptic currents (EPSCs) mediated by NMDA receptors (EPSCNMDAR)

Biochem/physiol Actions

NBQX disodium salt hydrate is a neuroprotective AMPA/kainate glutamate receptor antagonist.

Membrane fusion during exocytosis is mediated by assemblies of SNARE (soluble NSF-attachment protein receptor) and SM (Sec1/Munc18-like) proteins. The SNARE/SM proteins involved in vesicle fusion during neurotransmitter release are well understood, whereas little is known about the protein machinery that

Propagation of tau pathology is linked with progressive neurodegeneration, but the mechanism underlying trans-synaptic spread of tau is unknown. We show that stimulation of neuronal activity, or AMPA receptor activation, induces tau release from healthy, mature cortical neurons. Notably, phosphorylation
