    Enhanced Inhibition of Influenza A Virus Adhesion by Di- and Trivalent Hemagglutinin Inhibitors
    摘要:
    Multivalent carbohydrate-based ligands were synthesized and evaluated as inhibitors of the adhesion protein HA of the influenza A virus (IAV). HA relies on multivalency for strong viral adhesion. While viral adhesion inhibition by large polymeric molecules has proven viable, limited success was reached for smaller multivalent compounds. By linking of sialylated LAcNAc units to di- and trivalent scaffolds, inhibitors were obtained with an up to 428-fold enhanced inhibition in various assays.

  • Synthesis of Sialic Acids, Their Derivatives, and Analogs by Using a Whole-Cell Catalyst
    作者:Xun Lv、Hongzhi Cao、Baixue Lin、Wei Wang、Wande Zhang、Qian Duan、Yong Tao、Xue-Wei Liu、Xuebing Li

    Sialic acids (Sias) are important constituents of cell surface glycans. Ready access to Sias in large quantities would facilitate the development of carbohydrate‐based vaccines and small‐molecule drugs. We now present a facile method for synthesizing various natural forms and non‐natural derivatives or analogs of Sias by using a whole‐cell catalyst, which is constructed by adding a plasmid containing
    唾液酸(Sias)是细胞表面聚糖的重要成分。大量使用Sias可以方便地开发基于碳水化合物的疫苗和小分子药物。现在,我们提出了一种通过使用全细胞催化剂来合成Sias的各种天然形式和非天然衍生物或类似物的简便方法,该方法是通过将包含必需酶基因的质粒添加到大肠杆菌的代谢工程菌株中来构建的。掺入的酶(N-乙酰氨基葡萄糖2-表异构酶N-乙酰神经氨酸醛缩酶)使细胞催化剂可以通过易于扩展的发酵过程将各种简单廉价的糖类转化为各种与Sia相关的化合物。此外,使用这种全细胞生物转化结合三个常规酶促反应的合成提供了一系列复杂的含Sia的聚糖(唾液寡糖)及其带有不同取代基的衍生物。本文所述的方法应允许大规模且经济地生产Sias和唾液酸低聚糖,并且可以补充现有的化学和酶促策略。

    A seven-step synthetic route to a water-soluble azide-functionalized BF2–azadipyrromethene fluorochrome was developed; the fluorochrome shows λmax emission at 711 nm and a fluorescence quantum yield of 0.25. The fluorochrome can be effectively conjugated to alkyne-substituted carbohydrates by click chemistry in water at room temperature in 20 min by using CuSO4 (20 mol-%). The glycoconjugated fluorophores

  • Chemo-enzymatic synthesis of functionalized oligomers of N-acetyllactosamine glycan derivatives and their immobilization on biomaterial surfaces

    Poly-N-acetyllactosamines (poly-LacNAc, [-3Gal(beta 1-4)GlcNAc(beta 1-](n)) are terminal glycan structures present in glycoproteins and glycolipids. Their biological functions as ligands for galectins and as carriers of glycan epitopes are well documented. In the present paper we have characterized six novel functionalized beta-D-GlcNAc derivatives, including aglyca of varying hydrophobicity and molecular weight, as substrates for recombinant human beta 1,4 galactosyltransferase 1 (beta 4GalT-1). The sugar derivatives carry short or long amino- or azide-terminated linker molecules for further modification or immobilization. The linker chemistry had an impact on enzyme kinetics and enzymatic syntheses of N-acetyllactosamine derivatives (LacNAc, Gal(beta 1-4)GlcNAc(beta 1-R). The combination of beta 4GaIT-1 with bacterial beta 1,3-N-acetylglucosaminyltransferase (beta 3GlcNAc-T) resulted in the preparative syntheses of LacNAc oligomers with up to three LacNAc repeating units. All products were characterized by NMR and MS. The obtained LacNAc glycans were immobilized onto microtiter plates and their efficiency of binding of fungal galectin CGL2 was determined.
