Biological Activity for NBQX disodium salt

NBQX disodium salt is a selective and competitive AMPA and kainate receptor antagonist (IC₅₀ = 0.15 μM and 4.8 μM, respectively). NBQX blocks the antidepressant effects of 8-Hydroxy-DPAT hydrobromide (Cat. No. 0529), decreases mTOR and BDNF levels. NBQX is neuroprotective, anticonvulsant, antinociceptive and active in vivo.

NBQX disodium salt is a more water-soluble form of NBQX (Cat. No. 0373).
