  • Solid-Phase Synthesis of Core 8<i>O</i>-Glycan-Linked MUC5AC Glycopeptide
    作者:Makoto MAEMURA、Atsushi OHGAKI、Yuko NAKAHARA、Hironobu HOJO、Yoshiaki NAKAHARA
    DOI:10.1271/bbb.69.1575
    日期:2005.1
    The benzyl-protected disaccharide building blocks of core 8 O-glycan (15a/15b) for glycopeptide were stereoselectively synthesized by two glycosidation reactions with the glycosyl fluoride method. The building blocks were utilized in the solid-phase synthesis of a glycopeptide carrying two O-glycans with the consensus sequence of the tandem-repeat domain of MUC5AC. The synthetic glycopeptide was detached from the resin with reagent K, and subsequent debenzylation under conditions of low-acidity TfOH afforded glycopeptide 2. The synthetic sample will be used as a suitable standard in studies of the physicochemical or immunochemical characterization of mucin glycoforms.
    利用糖基化化物方法,通过两个糖苷化反应立体选择性地合成了用于糖肽的核心 8 O-聚糖(15a/15b)的苄基保护二糖构件。利用这些构件固相合成了含有两个 O-聚糖的糖肽,其序列与 MUC5AC 的串联重复结构域的共识序列一致。合成的糖肽用试剂 K 从树脂中分离出来,随后在低酸 TfOH 条件下进行脱苄基反应,得到糖肽 2。该合成样本将在粘蛋白糖形的物理化学或免疫化学表征研究中用作合适的标准。
  • An efficient access to protected disialylated glycohexaosyl threonine present on the leukosialin of activated T-lymphocytes
    作者:Latika Singh、Yuko Nakahara、Yukishige Ito、Yoshiaki Nakahara
    DOI:10.1016/s0008-6215(99)00313-4
    日期:2000.4
    The total synthesis of the threonine-linked core 2 class disialylated hexasaccharide in a completely protected form was accomplished for the first time. The L-threonine conjugate, N-(9-fluorenylmethoxycarbonyl)-O-(5-acetomido-4,7,8,9-tetra-O-benzyl-3,5-dideoxy-D-glycero-alpha-D-galacto-2-nonulopyranosylanic acid)-(2 --> 3)-(2,6-di-O-benzyl-beta-D-galactopyranosyl)-(1 --> 4)-2-acetamido-2-deoxy-3,6-di-O-benzyl-beta-D-glucopyranosyl-(1 --> 6)-[(5-acctamido-4,7,8,9-tetra-O-benzyl-3, 5-dideoxy-D-glycero-alpha-D-galacto-2-nonulopyranosylonic acid)-(2 --> 3)-2,6-di-O-benzyl-beta-D-galactopyranosyl-(1 --> 3)]-2-acetamido-2-deoxy-alpha-D-galactopyranosyl-(1d --> 4c:1f --> 4e)-dilactone}-L-threonine allyl ester was synthesized via stereocontrolled glycosylations employing readily accessible monosaccharidic blocks; t-butyl-diphenylsilyl-2-azido-2-deoxy-3, 6-di-O-benzyl-beta-D-glucopyranose, N-(9-fluorenylmethoxycarbonyl)-O-(2-azir-butylditnethylsilyl-2-deoxy-alpha-D-galactopyranosyl)-L-threonine allyl ester, 8, 9 and N-(9-fluorenylmethoxycarbonyl)-O-(2-azido-4,6-O-benzylidene-3-O-chloroacetyl-2-deoxy-alpha-D-galactopyranosy;)-L-threonine allyl ester. For the introduction of the amino acid. the azide group was used to temporarily mask the amino group of GalNAc so as to obtain an alpha-glycosidic linkage without participation from the C-2 substituent. The threonine was attached to the sugar unit at the monosaccharide stage to avoid loss of oligosaccharide at a later stage. The Fmoc and allyl ester protected amino acid at the reducing end facilitates efficient glycopeptide synthesis on solid-phase support. (C) 2000 Elsevier Science Ltd. All rights reserved.
