Semaglutide, a long-acting GLP-1 analogue, is a glucagon-like peptide-1 (GLP-1) receptor agonist. Semaglutide has the potential for type 2 diabetes treatment.

Semaglutide is a polypeptide that contains a linear sequence of 31 amino acids joined together by peptide linkages. It is an agonist of glucagon-like peptide-1 receptors (GLP-1 AR) and used for the treatment of type 2 diabetes. It has a role as a hypoglycemic agent, a glucagon-like peptide-1 receptor agonist, an anti-obesity agent, a neuroprotective agent and an appetite depressant. It is a polypeptide and a lipopeptide.
