    摘要: To provide a GLP-1 analogue long-acting prophylactic or therapeutic agent for diabetes, diabetic complications and/or obesity due to diabetes which provides an extended half-life of a GLP-1 analogue in the blood to prevent frequent administration, and is biodegradable and safe.The present invention provides a conjugate obtained by binding, to a GLP-1 analogue into which a mercapto group is incorporated, water soluble hyaluronic acid modification product obtained by incorporating a substituent via an amide bond to the carboxyl group of glucuronic acid portion of hyaluronic acid as a derivative thereof, using a specific condensing agent in an aprotic polar solvent; and a prophylactic or therapeutic agent having a durable blood glucose lowering effect for diabetes, diabetic complications or obesity.
