SR-95531 Chemical Properties,Usage,Production

Description

SR 95531 is a derivative of γ-aminobutyric acid (GABA) that acts as an antagonist of GABA_A receptors (K_i = 74-150 nM). When administered intravenously, it elicits seizures in mice. SR 95531 differs in action from bicuculline in that it antagonizes GABA-induced chloride currents but not those induced by pentobarbitone. It is effective against GABA_A receptor isoforms from mice, rats, and humans.

Uses

Gabazine Hydrobromide is a specific GABA receptor antagonist. Does not affect GABA-transaminase or glutamate-decarboxylase activitites.

Biological Activity

Selective, competitive GABA A receptor antagonist. Displaces [ 3 H]-GABA from rat brain membranes with a K i of 150 nM. Unlike bicuculline, selectively antagonizes GABA-induced Cl - currents with little action on pentobarbitone-induced currents. Also acts as a low affinity glycine receptor antagonist.

Biochem/physiol Actions

SR-95531 is a specific GABAA receptor antagonist that does not affect GABA-transaminase or glutamate-decarboxylase activities.
