Design, Synthesis, and Pharmacological Evaluation of Novel Quinolone Aryl Sulfonamide Derivatives as Potent GPR55 Antagonists

Docking studies of identified GPR55 ligands using a GPR55 inactive state model allow rationalizing key structural features involved in ligand–receptor binding. On this molecular basis, we have designed novel quinolone sulfonamide derivatives with optimized potency and efficacy. These novel molecules compounds are being synthesized and evaluated using a β-arrestin recruitment assay in CHO cells overexpressing human GPR55 and βarr2-GFP.Peer reviewe
