Abstract: The insulinotropic hormone glucagon-like peptide-1 (GLP-1) is rapidly inactivated in the body. In order to improve its stability, we replaced the enzymatic hydrolyzation position Ala(8)with Gly and replaced Ala(30) with Cys firstly. Then the modified peptide was further PEGylated at thiol group of Cys(30). Biological activity studies showed that the resulting mPEG-MAL-Gly(8)-Cys(30)-GLP-1(7-36)-NH(2) exhibited long-lasting effect while maintaining moderate glucose-lowering activity.
