GYKI 53655 hydrochloride
Chemical Name: 1-(4-Aminophenyl)-3-methylcarbamyl-4-methyl-3,4-dihydro-7,8-methylenedioxy-5H-2,3-benzodiazepine hydrochloride
Biological ActivityGYKI 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.
