    Scientific background

    Isoguvacine hydrochloride is a specific and potent agonist of GABA(A) receptors with an EC50 value of 3.7–17.3 µM, depending on the subunit composition1. It is a semirigid analogue of trans-4-aminocrotonic acid with limited conformational flexibility and is less potent than GABA1,2.

    GABA(A) receptors are members of the Cys-loop superfamily of ligand-gated ion channels. They mediate GABA action, a major inhibitory neurotransmitter, through the central nervous system, and play an important role in inhibiting cell excitation in the central nervous system. GABA(A) receptors are considered to be a major target of antiseizure drugs3,4.
