GABA receptors are a class of receptors that respond to the neurotransmitter gamma-aminobutyric acid (GABA), the chief inhibitory neurotransmitter in the vertebrate central nervous system. There are two classes of GABA receptors: GABAA and GABAB. GABAA receptors are ligand-gated ion channels (also known as ionotropic receptors), whereas GABAB receptors are G protein-coupled receptors (also known asmetabotropic receptors). It has long been recognized that the fast response of neurons to GABA that is blocked by bicuculline and picrotoxin is due to direct activation of an anion channel. This channel was subsequently termed the GABAA receptor. Fast-responding GABA receptors are members of family of Cys-loop ligand-gated ion channels. A slow response to GABA is mediated by GABAB receptors, originally defined on the basis of pharmacological properties.

    Topiramate lithium
    		Activator
    Topiramate (McN 4853) lithium is a broad-spectrum antiepileptic agent. Topiramate lithium is a GluR5 receptor antagonist. Topiramate produces its antiepileptic effects through enhancement of GABAergic activity, inhibition of kainate/AMPA receptors, inhibition of voltage-sensitive sodium and calcium channels, increases in potassium conductance, and inhibition of carbonic anhydrase.

    EF-1502
    EF-1502 is a potent and selective GABA transporter inhibitor with GAT1 and BGT1 inhibitory activity. EF-1502 produces a synergistic anti-epileptic effect when used in combination with Tiagabine (HY-B0696), a compound used to suppress epileptic seizures. The dosing combination of EF-1502 exhibited reduced anti-epileptic efficacy and dyskinesia when used with THIP (HY-10232). The mechanism of EF-1502 differs significantly from Tiagabine, suggesting a unique role in the inhibitory strategy.
