Biological Activity for GYKI 53655 hydrochloride

GYKI 53655 hydrochloride is a non-competitive AMPA and kainate receptor antagonist. Analog of GYKI 52466 (Cat. No. 1454). Prolongs the survival time after MgCl₂- induced global cerebral ischemia. Exhibits anticonvulsant activity. Also blocks GluK3 homomeric receptors (IC₅₀ = 63 μM) and GluK2b(R)/GluK3 heteroreceptors (IC₅₀ = 32 μM) at high concentrations.
