内容摘要：

    Heparin is a highly sulfated, complex polysaccharide and widely applied as clinical anticoagulant with more than 100 tons of heparin used annually. A projected global market for heparin is expected to reach approximately $16.3 billion by 2025. This seminar presents the progress of heparin related glycoengineering/glycomics/interactome studies, include: i) Enzymatic generation of highly anticoagulant from bovine intestinal heparin: we converted bovine intestinal heparin (BIH), which has a low anticoagulant activity, to USP heparin by the treatment with 6-O-sulfotransferases and/or 3-O-sulfotransferase;  ii) Heavy heparin: A stable isotope-enriched, chemoenzymatically-synthesized, poly-component drug: in this work, we chemoenzymatically synthesized perdeuteroheparin from biosynthetically enriched heparosan precursor obtained from microbial culture in deuterated medium. Chemical de-N acetylation, chemical N-sulfation, enzymatic epimerization, and enzymatic sulfation with recombinant heparin biosynthetic enzymes afforded perdeuteroheparin comparable to pharmaceutical heparin. iii) Alzheimer’s disease related glycomics/interactome research; iv) Development of heparin based bionanomaterials.
