Lesogaberan (AZD-3355) hydrochloride is a potent and selective GABAB receptor agonist with an EC50 of 8.6 nM for human recombinant GABAB receptor. The affinity (Kis) of Lesogaberan hydrochloride for rat GABAB and GABAA receptors, as measured by displacement of [3H]GABA binding in brain membranes: 5.1 nM and 1.4 μM, respectively. Lesogaberan hydrochloride inhibits transient lower esophageal sphincter relaxation through a peripheral mode of action[1].
Lesogaberan hydrochloride (3-30 nM) enhances human islet cell proliferation in vitro[2].
Lesogaberan hydrochloride potently stimulates recombinant human GABAB receptors and inhibits transient lower esophageal sphincter relaxation (TLESR) in dogs, with a biphasic dose-response curve[1].
Oral Lesogaberan (0.08 mg/mL; 48 hours) hydrochloride protects human islet β-cells from apoptosis in islet grafts in mice[2].
Lesogaberan (7 μmol/kg) hydrochloride shows high oral availability (88% in the dog and 100% in the rat) and relatively low systemic clearance in female SpragueDawley rats[1].
