    Synthesis and anti-influenza virus activity of 4-guanidino-7-substituted Neu5Ac2en derivatives
    摘要:
    Substitution of 7-OH by small hydrophobic groups on zanamivir resulted in the retaining of low nanomolar inhibitory activities against not only influenza A virus sialidase but also influenza A virus in cell culture. These compounds were prepared by treatment of the corresponding 7-substituted sialic acids derived from 4-modified N-acetyl-D-mannosamine (ManNAc) using enzyme-catalyzed aldol condensation.

  • Chemoenzymatic synthesis of sialosides containing C7-modified sialic acids and their application in sialidase substrate specificity studies

    chemoenzymatic synthesis of α2-3- and α2-6-linked sialyl para-nitrophenyl galactosides in which the C7-hydroxyl group in sialic acid (N-acetylneuraminic acid, Neu5Ac, or 2-keto-3-deoxynonulosonic acid, Kdn) was systematically substituted by -F, -OMe, -H, and -N3 groups. Substrate specificity study of bacterial and human sialidases using the obtained sialoside library containing C7-modified sialic acids showed
    唾液酸苷中唾液酸甘油侧链的修饰通过唾液酸结合蛋白和唾液酸酶来调节其识别。然而,有限的工作集中在具有C7修饰的唾液酸的唾液酸化物的合成和功能研究上。在这里,我们报告化学合成C4修饰的ManNAc和甘露糖及其作为唾液酸前体在高效一锅三酶系统中化学合成α2-3和α2-6连接的唾液酸对硝基苯基半乳糖苷的唾液酸前体的应用。唾液酸中的C7-羟基(N-乙酰神经氨酸,Neu5Ac或2-酮-3-脱氧壬二酸,Kdn)被-F,-OMe,-H和-N3系统取代。使用获得的含有C7修饰的唾液酸的唾液酸文库,对细菌和人唾液酸酶的底物特异性研究表明,含有C7-脱氧Neu5Ac的唾液酸苷是所有测试的细菌唾液酸酶(而非人NEU2)的选择性底物。从唾液酸酶底物特异性获得的信息可用于指导对细菌唾液酸酶具有选择性的新抑制剂的设计。

    日期:1994.12
    7-Deoxy-N-acetylneuraminic Acid and 7-O-methyl-N-acetylneuraminic acid were synthesized through the sialic acid aldolase-cataIyzed aldol addition reactions of 4-deoxy-N-acetyl-D-mannosamine and 4-O-methyl-N-acetyl-D-mannosamine, respectively, with pyruvate. The obtained sialic acids will be used as probes for the investigation of the unusual mechanism of a novel sialidase from leech.
  • New chemo-enzymatic route toward N-acetylneuraminic acid derivatives with alkyl groups at C-7 hydroxyl group
    作者:Jordi Calveras、Yasuhito Nagai、Israt Sultana、Yuji Ueda、Toshinori Higashi、Mitsuru Shoji、Takeshi Sugai
    DOI:10.1016/j.tet.2010.04.045
    日期:2010.6
    Based on chemo-enzymatic regio- and stereoselective reactions, new routes toward C-4 substituted N-acetyl-D-mannosamine (ManNAc) and the corresponding sialic acids from D-glucal were established. Lipase-catalyzed regioselective transformation of n-glucal and related substrates furnished precursors on which carbamate and alkyl substituent were properly introduced at C-3 and at C-4, respectively. Cyclic carbamate formation through rhodium-nitrenoid intermediates with iodobenzene pivalate and tertbutyl alcohol proceeded in manna-configured at C-2 as well as alpha- at C-1, exclusively. Ring opening and deprotection under mild conditions furnished the target ManNAc derivatives, which were the substrates for aldolase-catalyzed reactions. (C) 2010 Elsevier Ltd. All rights reserved.
