Background

Lesogaberan (AZD-3355) is a potent and selective GABAB receptor agonist with an EC50 of 8.6 nM for human recombinant GABAB receptors. Binding affinity (Kis) of 5.1 nM and 1.4 μM for rat brain GABAB and GABAA receptors, respectively[1].

Lesogaberan (3-30 nM) enhances human islet cell proliferation in vitro[2]. Cell Proliferation Assay[2] Cell Line: Human islet cells

Lesogaberan (AZD3355) 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) protects human islet β-cells from apoptosis in islet grafts in mice[2]. Lesogaberan (7 μmol/kg) shows high oral availability (88% in the dog and 100% in the rat) and relatively low systemic clearance in female SpragueDawley rats[1]. Animal Model: Diabetic NOD/scid mice were implanted with human islets[2]
