  • A versatile and new highly stereoselective approach to the synthesis of l-glycero-d-manno-heptopyranosides
    作者:G.J.P.H Boons、G.A van der Marel、J.H van Boom

    The reaction of (phenyldimethyl)silylmethylmagnesium chloride with benzyl 2,3,4-tri-O-benzyl-α-D-manno-hexodialdo-1,5-pyranoside affords the corresponding L-glycero-D-manno-addition product having at C-7 the phenyldimethylsilyl (PDMSi) group. The latter silanyl compound survived benzylation as well as glycosylation at OH-6, and the PDMSi group could be unmasked with overall retention of configuration

    subjected to strong alkaline conditions (4 M KOH, 120 °C, 18 h). The resulting products were analyzed by 1 H NMR spectroscopy and electrospray mass spectrometry. It was found that phosphate substituents were stable under these conditions and neither migration nor hydrolysis was observed except for the heptose 7-phosphate, which gave a substantial amount of phosphate hydrolysis. In phosphoethanolamine-substituted

  • The Inhibition of Liposaccharide Heptosyltransferase WaaC with Multivalent Glycosylated Fullerenes: A New Mode of Glycosyltransferase Inhibition

    (L‐glycero‐D‐manno‐heptopyranoses) are found in important bacterial glycolipids such as lipopolysaccharide (LPS), the biosynthesis of which is targeted for the development of novel antibacterial agents. This work describes the synthesis of a series of fullerene hexa‐adducts bearing 12 copies of peripheral sugars displaying the mannopyranose core structure of bacterial l,d‐heptoside. The multimers were assembled
    在重要的细菌糖脂(例如脂多糖(LPS))中发现了l,d-庚糖苷(L-甘油-D-甘露聚糖-庚糖),其生物合成旨在开发新型抗菌剂。这项工作描述了一系列富勒烯六加合物的合成,这些加合物带有12个拷贝的外围糖,显示了细菌l,d-庚酮的甘露吡喃糖核心结构。最后一步是通过有效的铜催化炔烃-叠氮化物环加成反应组装多聚体。将最终的富勒烯糖球作为庚基转移酶WaaC的抑制剂进行分析,该糖基转移酶催化第一个L的掺入将庚糖转化为LPS。有趣的是,最终分子的抑制在低微摩尔范围被发现(IC 50 = 7-45μ中号),而相应的单体苷显示高微摩尔至毫摩尔低抑制水平(IC 50总是高于400μ中号)。当以“每糖”为基础进行评估时,这些抑制数据表明,在每种情况下,富勒烯的一个糖苷对WaaC的平均亲和力在以多聚体形式显示时均得到显着增强,从而证明了意想不到的多价效应。迄今为止,从未用糖基转移酶证实过这种多价抑制方式。
  • Five monophosphates of methyl l-glycero-α-d-manno-heptopyranoside: synthesis, hydrolysis and migrations
    作者:Barbara Grzeszczyk、Otto Holst、Sven Müller-Loennies、Aleksander Zamojski
    DOI:10.1016/s0008-6215(98)00037-8
    日期:1998.2
    From suitably protected methyl alpha-D-mannopyranosides five methyl L-glycero-alpha-D-manno-heptopyranosides were synthesized by the one-carbon-atom chain elongation at C-6 and converted to five monophosphates (1-5) having the PO(OH)(2) group at O-2, -3, -4, -6 and -7. Compounds 1-5 were exposed to acidic and basic hydrolytic conditions used in lipopolysaccharide analysis and the products and their proportion were determined. Under acidic conditions, besides hydrolysis of the glycoside, migrations and hydrolytic cleavage of the phosphate residue were found. Under basic conditions the phosphates were stable.
