Description générale

NBQX [2,3-dihydroxy-6-nitro-7-sulphamoyl-benzo(F)quinoxaline] is a competitive antagonist, which shows high affinity to 2-amino-3-hydroxy-5-methyl-4-isoxazol propionic acid (AMPA) receptor than kainite receptor.

Application

NBQX hydrate has been used:
  • as a non-N-methyl-D-aspartate receptor (NMDA) 2-amino-3-hydroxy-5-methyl-4-isoxazol propionic acid (AMPA) receptor antagonist to monitor gonadotropin responses
  • α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptor (AMPAR) antagonist in monocytes
  • AMPA and N-methyl-D-aspartate receptor (NMDA) antagonist in migrating interneurons expressing potassium-chloride cotransporter (shKCC2)

Actions biochimiques/physiologiques

NBQX [2,3-dihydroxy-6-nitro-7-sulphamoyl-benzo(F)quinoxaline], an anticonvulsant provides protection against white matter damage in spinal cord crush injury and also protects oligodendrocyte in experimental autoimmune encephalomyelitis (EAE). However, its role in preventing inflammation in EAE is not yet clear.
Neuroprotective AMPA/kainate glutamate receptor antagonist.

Seizures occur due to an imbalance between excitation and inhibition, with the balance tipping towards excitation, and glutamate is the predominant excitatory neurotransmitter in the central nervous system of mammals. Since upregulation of expression and/or function of glutamate receptors can
