  6″-Azido-6″-deoxy-UDP-N-acetylglucosamine as a glycosyltransferase substrate

  摘要：

  6 ''-Azido-6 ''-deoxy-UDP-N-acetylglucosamine (UDP-6Az-GlcNAc) is a potential alternate substrate for N-acetylglucosaminyltransferases. This compound could be used to generate various glycoconjugates bearing an azide functionality that could in turn be subjected to further modification using Staudinger ligation or Huisgen cycloaddition. UDP-6Az-GlcNAc is synthesized from alpha-benzyl-N-acetylglucosaminoside in seven-steps with an overall yield of 6%. It is demonstrated to serve as a substrate donor for the glycosyl transfer reaction catalyzed by the human UDP-GlcNAc:polypeptidyltransferase (OGT) to the acceptor protein nucleoporin 62 (nup62).

  beta4GalTs, donor substrate specificity studies of two bacterial beta3GlcNAcTs from Helicobacter pylori (Hpbeta3GlcNAcT) and Neisseria meningitidis (NmLgtA), respectively, using a library of 39 sugar nucleotides were carried out. The two beta3GlcNAcTs have complementary donor substrate promiscuity and 13 different trisaccharides were produced. They were used to investigate the acceptor substrate specificities

  advantage of relaxed donor specificity and strict acceptor specificity of glycosyltransferases to label target glycan epitopes with bioorthogonal reactive groups carried by unnatural nucleotide sugars in vitro. The subsequent covalent conjugation by bioorthogonal chemical reactions with either fluorescent or affinity tags allows further visualization, quantification, or enrichment of target glycan epitopes

  近年来，酶促生物正交标记策略的发展为探测结构确定的聚糖表位提供了令人兴奋的可能性。该策略利用放宽的供体特异性和糖基转移酶的严格受体特异性来利用体外由非天然核苷酸糖携带的生物正交反应基团标记目标聚糖表位。随后通过与荧光标记或亲和标记的生物正交化学反应进行的共价缀合，可以使目标聚糖表位进一步可视化，定量或富集。然而，由于非天然核苷酸糖的有限可用性，已经阻碍了酶标记策略的应用和发展。在此处，描述了将化学合成和酶促合成相结合的平台，以方便地制备经各种生物正交反应基团修饰的非天然核苷酸糖。通过该平台，成功合成了25个UDP-GlcNAc和UDP-GalNAc衍生物，其中包括开发最深入的生物正交官能团。此外，还评估了这些化合物在酶促生物正交标记反应中的潜在应用。

  A bisecting glycan-bridged conjugation strategy that enables site-specific conjugation of glycoproteins without the need for chemical synthesis of oligosaccharide and amino acid engineering is disclosed. Application of this method is demonstrated by conjugation of human and mouse antibodies with a cytotoxin. This strategy preserves the Fc effector function of the antibodies and provides the ability to remodel glycans to fine-tune the immunogenicity and pharmacokinetic properties of antibody-drug conjugates through glycoengineering.
