(+)-Bicuculline (methochloride)

(+)-Bicuculline methobromide is a potent GABAA blocker. (+)-Bicuculline methobromide alters membrane properties and firing pattern. (+)-Bicuculline methobromide reduces the Apamin-sensitive afterhyperpolarization, while Apamin is a toxin isolated from bee venom to block small conductance Ca2+ -activated K+ channels. (+)-Bicuculline methobromide facilitates burst firing via blocking apamin-sensitive Ca2+ -activated K+ current.
