Glucagon-like Peptide-1 (GLP-1) analogues were designed through the modification of the enzymatic hydrolyzation position. The synthesis of GLP-1 analogues was implemented rapidly and efficiently under microwave irradiation, using Fmoc/t-Bu orthogonal protection solid phase strategy. The crude peptides were purified by preparative RP-HPLC. The results of biological activity research showed that the GLP-1 analogues had great resistance to the degradation by dipeptidyl peptidase (DPP IV) and decreased the blood glucose prominently. The molecular weight and purity of the GLP-1 analogues have been confirmed through the electrospray mass spectrometry analysis and the HPLC analysis.
