General description
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[1]
- 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)
Biochem/physiol Actions
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.
