Temgicoluril does not have a direct effect on sleep, however, it enhances the effectiveness of sleep medicines and normalizes the course of disturbed sleep. Temgicoluril alleviates or eliminates the manifestations of nicotine dependence that occur after smoking cessation .
Many commonly used sedative and anxiolytic drugs that affect the GABA receptor complex are not agonists. These drugs act instead as positive allosteric modulators (PAMs) and while they do bind to the GABA receptors, they bind to an allosteric site on the receptor and cannot induce a response from the neuron without an actual agonist being present.
Lormetazepam binds to the benzodiazepine receptor which in turn enhances the effect of the GABA A receptor producing its therapeutic effects as well as adverse effects. When lormetazepam binds to the benzodiazepine receptor sites in sufficient quantities it produces sedation which is used clinically as a therapeutic treatment for insomnia.
The most striking discovery was the finding that baclofen (β-parachlorophenyl GABA), a clinically employed muscle relaxant [44] [45] mimicked, in a stereoselective manner, the effect of GABA. Later ligand-binding studies provided direct evidence of binding sites for baclofen on central neuronal membranes.
A GABA reuptake inhibitor (GRI) is a type of drug which acts as a reuptake inhibitor for the neurotransmitter gamma-Aminobutyric acid (GABA) by blocking the action of the gamma-Aminobutyric acid transporters (GATs). This in turn leads to increased extracellular concentrations of GABA and therefore an increase in GABAergic neurotransmission. [1]
The ionotropic GABA A receptor protein complex is also the molecular target of the benzodiazepine class of tranquilizer drugs. Benzodiazepines do not bind to the same receptor site on the protein complex as does the endogenous ligand GABA (whose binding site is located between α- and β-subunits), but bind to distinct benzodiazepine binding sites situated at the interface between the α- and ...
