(E)-GABAB receptor antagonist 1 decreases GABA-induced IP3 (inositol trisphosphate) production with IC50 of 37.9 μM.GABAB receptor antagonist 1 is a selective and negative allosteric modulator of GABAB (γ-Aminobutyric acid) receptors.
Lesogaberan is an effective and selective GABAB receptor agonist (EC50: 8.6 nM for human recombinant GABAB receptors). For rat brain GABAB and GABAA receptors, the binding affinity (Kis) is 5.1 nM and 1.4 μM, respectively.
Lesogaberan (AZD-3355) napadisylate is a potent and selective agonist of GABA B receptors, with an EC 50 of 8.6 nM for human recombinant GABA B receptors. It demonstrates an affinity (Ki) of 5.1 nM for rat GABA B receptors and 1.4 μM for GABA A receptors, as determined by its displacement of [3H]GABA binding in brain membranes. Notably, Lesogaberan napadisylate exerts a peripheral mode of action, inhibiting transient lower esophageal sphincter relaxation.
SCH 50911 is (+)-(S)-5,5-dimethylmorpholinyl-2-acetic acid and is a selective, orally-active and competitive γ-Aminobutyric acid B GABA(B) receptor antagonist, binds to GABA(B) receptor (IC50: 1.1 μM). SCH 50911 antagonizes GABA(B) autoreceptors, increasi
CGP 36742 is a selective antagonist of the GABAB receptor that can penetrate the blood-brain barrier after peripheral administration (IC50: 32 μM). It is useful in the treatment of depression.
