Mechanism of Action

Targets/IC₅₀/Ki	GABAA receptor 2 μM
In vitro	(+)-Bicuculline (1-100μM) dose-dependently inhibits the Cl^- conductance generated by 40 μM GABA. This compound also inhibits the agonist action of GABA at 40 μM at α₁β₂γ_2L receptors. It at 1 and 3 μM increases GABA EC50 values 1.6 times (41.0-67.0 μM) and 3.6 times (36.1-129.0 μM), respectively. Atα₁β₂γ_2L GABA_A receptors, this chemical displays the general property of the competitive antagonist, producing a parallel shift of GABA concentration-effect curves and having no effect on the maximal response of GABA. In addition to being a potent GABAA receptor antagonist, it also blocks Ca²⁺-activated potassium channels.
