Chemical Name:(±)-4-(4-Aminophenyl)-1,2-dihydro-1-methyl-2-propylcarb
amoyl-6,7-methylenedioxyphthalazine
Biological Activity:
Novel, potent, non-competitive AMPA receptor antagonist (IC50
= 2.8 μM ). Acts allosterically
at the same regulatory site as GYKI 52466 and 53655 and other benzodiazepines
but does not bind to the central diazepine binding site. Selective for AMPA
relative to kainate receptor sub-types. Similar potency to GYKI 53655. Anticonvulsant
in vivo.
