Biologische Aktivität
AMPA receptor[1]
NBQX disodium (FG9202 disodium) has a high affinity for AMPA and kainate binding sites with little or no affinity for the glutamate recognition site on the NMDA receptor complex[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
NBQX disodium is neuroprotective in a focal ischaemia model in the rat when given as an i.v. bolus dose of 30 mg/kg at the time of MCA occlusion and again at 1 h post occlusion[1].
