The Novel Dual GLP-1/GIP Receptor Agonist DA-CH5 Is Superior to Single GLP-1 Receptor Agonists in the MPTP Model of Parkinson’s Disease

Background:Parkinson’s disease (PD) is a progressive neurodegenerative disease for which there is no cure. In a clinical trial, the glucagon-like peptide-1 (GLP-1) receptor agonist exendin-4 has shown good protective effects in PD patients. The hormone glucose-dependent insulinotropic polypeptide ( GIP) has also shown protective effects in animal models of PD. Objective:We tested DA-CH5, a novel dual GLP-1/GIP receptor agonist. Methods:DA-CH5...
