Summary of report
Professor Zhao Junfeng focuses on the research in the frontier areas of chemistry and life science, and solves key scientific problems in the field of chemical biology by developing new reactions and new reagents in organic chemistry. After eight years of hard work, Professor Zhao Junfeng has achieved original and systematic research results in the field of chemical synthesis and precise modification of peptides and proteins. Professor Zhao Junfeng proposed the concept of condensation reagent design with alkenyl activated ester as the stable intermediate, and discovered two original polypeptide condensation reagents of acetylenamide and dienone, which provided a powerful tool for solving the racemization problem of the chiral center of α-amino acids in the synthesis of polypeptides. These two compounds can greatly reduce the production cost of peptide drugs, not only have important academic value, but also have broad application prospects in large-scale synthesis of peptide drugs, and are expected to provide transformative solutions for large-scale green production of peptide drugs. In this report, Professor Zhao Junfeng will detail the research progress of these two condensation reagents and explore the challenges and opportunities for green synthesis of polypeptides.
