Abstract
Semaglutide is currently the most promising antidiabetic drug, especially for the treatment of type 2 diabetes mellitus, due to its excellent efficacy in glycemic control and weight loss. However, the production of semaglutide remains high cost, and high yield, low cost, and high purity still remains a challenge. Herein, we reported a convenient and high-yield strategy for the preparation of semaglutide through fragmented condensation coupling, involving solid-phase peptide synthesis of tetrapeptide and on-column refolding and on-column enzyme cleavage based inclusion body expression of Lys26Arg34GLP-1 (11-37) with fused protein tags in an X-Y-D4K-G pattern. The optimized N-terminal protein tag significantly boosts inclusion body expression level, while on-column refolding and on-column enzyme cleavage avoid precipitation, enhancing efficiency and yield together with one-step purification. The successful preparation of semaglutide is expected to achieve large-scale industrial production with low cost, high yield and high purity.
