Bicuculline (methobromide)

Bicuculline methobromide is a selective GABAA Receptor antagonist with an IC50 value of 3 μM. Bicuculline methobromide induces clonic tonic convulsions in mammals and can also be used to block Ca2+ activated potassium channels. Bicuculline methobromide can be used in studies of epilepsy and other related psychiatric disorders[1][2].
