γ-Aminobutyric acid (GABA) is an amino acid derivate, synthesized from glutamate by the pyridoxal-L-phosphate (PLP)-dependent enzyme, glutamate decarboxylase (GAD)1. GABA provides the primary inhibitory signaling in the adult mammalian brain (CNS), and, to some degree of controversy, exerts a depolarizing response in the developing brain2.
GABA is an agonist of two main receptor classes in the CNS: GABAA, an ionic ligand-gated channel, and GABAB, a metabotrophic, G-protein coupled receptor. GABAA is assembled by 5 out of 16 possible subunits with α, β and either a γ or a δ (2:2:1 stoichiometry) being the most common. With an EC50 between 3 to 12 μM it interacts with GABA to allow either an influx or an efflux of Cl- ions into and out of the cell, respectively3.
Bicuculline (BIC) is a competitive allosteric inhibitor of GABAA-induced currents with an IC50 of 1-3 μM4. BIC has been employed to model epileptic seizures in hippocampal slices5, to induce schizophrenia-like symptoms in the pre-frontal cortex6, and is an essential research tool in the study of various psychomotor and behavioral defects4-6.
(+)-Bicuculline (#B-135) is a highly pure, synthetic, and biologically active compound.
