    An efficient glycosylation reaction for the synthesis of asialo GM2 analogues
    摘要:
    We investigated the coupling reaction of glycosyl donors N-trichloroethoxycarbonyl-galactosamine-O-trichloroacetimidate (2a) and N-p-nitrobenzyloxycarbonyl-galactosamine-O-trichloroacetimidate (2b) with the 4'-OH of lactose derivatives (3a-d) to synthesize key intermediates of asialo GM2 analogues, and found that the glycosylation yield with 2a was 90% or more in all investigated cases.

  • Syntheses of cellotriose and cellotetraose analogues as transition state mimics for mechanistic studies of cellulases
    作者:Shogo Noguchi、Shintaro Takemoto、Shun-ichi Kidokoro、Kazunori Yamamoto、Masaru Hashimoto
    DOI:10.1016/j.bmc.2011.04.048
    日期:2011.6
    Cellotriose and cellotetraose analogues carrying cyclohexene rings were developed as molecular probes which are expected to mimic the transition state conformation of hydrolysis by cellulases. The cyclohexene ring was placed at the pyranose ring being expected to locate the −1 subsite of the enzyme. In order to evaluate these probes, sulfur derivatives of cellotriose and cellotetraose were also synthesized
    带有环己烯环的纤维三糖和纤维四糖类似物被开发为分子探针,有望模拟纤维素酶水解的过渡态构象。将环己烯环置于吡喃糖环上,预期其位于酶的-1个亚位点。为了评估这些探针,还合成了纤维三糖和纤维四糖的硫衍生物作为模拟天然纤维素稳定构象的耐酶类似物。使用差示扫描量热法的结合测定法表明,引入环己烯环对于与来自腐质霉(Humicola insolens)的内切葡聚糖酶NCE5的络合是有效的。

    Methyl glycosides of L-sorbopyranoside, D-fructopyranoside, D-glucosaminopyranoside, 2,3-dehydro-2,3-dideoxyglucopyranoside, cellobiose, lactose, and maltose and the 1-azido derivatives of glucose, cellobiose, lactose, and maltose have been converted into the corresponding uronic acids in moderate to excellent yields by TEMPO-mediated anodic oxidation. The anode proves to be an advantageous alternative

    3′,6′-anhydro-6-bromo-6-deoxy derivative, from which 6-thio derivatives were prepared, and methyl 3′,4′-O-isopropylidene-β-lactoside gave the 6,6′-dibromo-6,6′-dideoxy derivative. A dibromide was prepared also from methyl 4′,6′-O-benzylidene-β-lactoside by bromination with Ph3P-CBr4, acetylation, and then treatment with N-bromosuccinimide. Various 6,6′-dithio derivatives were prepared from the 6,6′-dibromide

  • Chemical synthesis using enzymatically generated building units for construction of the human milk pentasaccharides sialyllacto-<i>N</i>-tetraose and sialyllacto-<i>N</i>-neotetraose epimer
    作者:Dirk Schmidt、Joachim Thiem

    日期:——

    α,2-3- and α,2-6-sialylated lactosaminide precursor structures obtained by various enzymatic procedures could be used for glycosylations employing triflic acid/N-iodosuccinimide. Easily accessible selectively protected lactoside derivatives served as acceptor disaccharides to give the corresponding human milk pentasaccharides in good yields. These were characterized by spectroscopic means in the form of their peracetylated derivatives.

    通过各种酶法获得的α,2-3-和α,2-6-唾液酸化的乳糖氨基糖前体结构可用于利用三氟乙酸/N-碘代琥珀酰亚胺进行糖基化。易获得的有选择性保护的乳糖苷衍生物作为受体二糖,可高产率地给出相应的人乳五糖。这些通过光谱手段以过乙酰化衍生物的形式进行表征。
  • Studies of the molecular recognition of synthetic methyl β-lactoside analogues by Ricinus communis agglutinin
    作者:Alfonso Rivera-Sagredo、Jesús Jiménez-Barbero、Manuel Martín-Lomas、Dolores Solís、Teresa Díaz-Mauriño
    DOI:10.1016/0008-6215(92)80055-6
    日期:1992.8
    The 2-, 3-, 6-, 2'-, 3'-, 4'-, and 6'-deoxy derivatives and the 3-O-methyl derivative of methyl beta-lactoside have been synthesised and their binding to the galactose-specific agglutinin from Ricinus communis (RCA-120) has been investigated. The results indicate that HO-3,4,6 of the beta-D-galactopyranose moiety are the key polar groups. The main difference from the closely related ricin lectin RCA-60
    已经合成了甲基β-乳糖苷的2-,3-,6-,2'-,3'-,4'-和6'-脱氧衍生物和3-O-甲基衍生物,并且它们与半乳糖结合研究了来自蓖麻的特异性凝集素(RCA-120)。结果表明,β-D-吡喃半乳糖部分的HO-3、4、6是关键的极性基团。与紧密相关的蓖麻毒素凝集素RCA-60的主要区别在于D-吡喃葡萄糖部分的HO-6,这似乎有助于碳水化合物与RCA-60的结合而不与RCA-120的结合。
