The Uses of NBQX DISODIUM SALT
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)
The Uses of NBQX DISODIUM SALT
A potent and discriminating antagonist for AMPA binding sites. This compound has neuroprotective properties.
Definition
ChEBI: 2,3-Dioxo-6-nitro-7-sulfamoylbenzo(f)quinoxaline is a member of naphthalenes and a sulfonic acid derivative.
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.
Biological Activity
Potent, selective and competitive AMPA receptor antagonist. Neuroprotective and anticonvulsant; active in vivo . More water soluble disodium salt of NBQX (2,3-Dioxo-6-nitro-1,2,3,4-tetrahydrobenzo[f]quinoxaline-7-sulfonamide ). Also available as part of the AMPA Receptor Tocriset™ .
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.
