    摘要:
    由碳水化合物介导的生物学重要事件的不断发现引起了人们对寡糖合成和糖苷键形成新方法开发的极大兴趣。在本文中,我们报告了 2,3-脱水呋喃糖硫糖苷 (1, 5) 和糖基亚砜 (2, 6),其中羟基 C-2 和 C-3 被“保护”为环氧化物,糖基化醇与极高的立体声控制度。与这种全新类型的糖基化剂反应的主要或唯一产物是其中新形成的糖苷键与环氧化物部分顺式。我们进一步证明,随后环氧化物部分的亲核打开在碱性条件下进行,以高产率和良好至极好的区域选择性得到产物。主要的开环产物具有阿拉伯立体化学,因此该方法构成了合成阿拉伯呋喃糖苷的新方法。在环...

  • Stereoselective synthesis of Arabidopsis CLAVATA3 (CLV3) glycopeptide, unique protein post-translational modifications of secreted peptide hormone in plant
    作者:Sophon Kaeothip、Akihiro Ishiwata、Yukishige Ito
    DOI:10.1039/c3ob41212a

    The unique hydroxylproline (Hyp)-linked O-glycan modification is a common process in hydroxyproline-rich glycoproteins (HRGPs). The modification occurs through post-translational hydroxylation at 4-position of proline residues some of which are followed by O-glycosylation at the resulting Hyp which is also found in some secreted peptide hormones such as CLAVATA3 (CLV3) of Arabidopsis thaliana plants. An active mature CLV3 is a tridecapeptide linked to β-L-Araf-(1→2)-β-L-Araf-(1→2)-β-L-Araf at a Hyp residue in the center of the peptide sequence such as Arg-Thr-Val-Hyp-Ser-Gly-Hyp(L-Arafn)-Asp-Pro-Leu-His-His-His (n = 3). We report here the synthesis of the secreted and modified CLV3 glycopeptide with all glycoforms (Araf0–3CLV3) of A. thaliana plants. A highly stereoselective β-arabinofuranosylation of Hyp derivatives as the key step of the synthesis of CLV3 glycopeptide was achieved by NAP ether-mediated IAD, which was effectively applied to the synthesis of oligoarabinosylated hydroxylproline [Hyp(L-Araf1–3)] derivatives. Fmoc-solid phase peptide synthesis was carried out using COMU as the coupling reagent for the introduction of [Hyp(L-Araf0–3)] derivatives as well as further elongation to the CLV3 glycopeptides.
    独特的羟脯氨酸(Hyp)连接的O-糖基化修饰是羟脯氨酸富集糖蛋白(HRGPs)中的常见过程。这种修饰通过在脯氨酸残基的4位进行翻译后羟基化发生,其中一些随后在生成的Hyp上发生O-糖基化,这在一些分泌的肽类激素中也存在,例如拟南芥植物中的CLAVATA3 (CLV3)。成熟的活性CLV3是一个十三肽,与β-L-Araf-(1→2)-β-L-Araf-(1→2)-β-L-Araf在肽序列中心的Hyp残基连接,例如Arg-Thr-Val-Hyp-Ser-Gly-Hyp(L-Arafn)-Asp-Pro-Leu-His-His-His (n = 3)。我们在这里报告了合成所有糖型(Araf0–3CLV3)的拟南芥植物分泌和修饰的CLV3糖肽。通过NAP醚介导的IAD实现了对Hyp衍生物的高度立体选择性β-阿拉伯呋喃糖基化,这是合成CLV3糖肽的关键步骤,并有效地应用于合成寡阿拉伯糖基化羟脯氨酸[Hyp(L-Araf1–3)]衍生物。使用COMU作为偶联试剂,通过Fmoc固相肽合成引入了[Hyp(L-Araf0–3)]衍生物,并进一步延伸至CLV3糖肽。

    1-benzenesulfinyl piperidine, or diphenyl sulfoxide, and trifluoromethanesulfonic anhydride in dichloromethane at −55 °C, reaction with glycosyl acceptors affords anomeric mixtures with little or no selectivity. The analogous 2-O-benzyl-3,5-O-(di-tert-butylsilylene)-α-d-thioarabinofuranoside also showed no significant selectivity under the 1-benzenesulfinyl piperidine or diphenyl sulfoxide conditions.

    A reliable and convenient method for determining the configuration and conformation of the furanose ring in carbohydrates and nucleosides by vibrational circular dichroism (VCD) spectroscopy is described. Diastereomeric pairs of several furanose monosaccharides and nucleosides were prepared, and their VCD spectra were analyzed. The results revealed that VCD spectroscopy elucidates the equibrated state

    Thioglycosidic bonds are of utmost importance in biomolecules as their incorporation led to more stable glycomimetics with potential drug activities. Until now only chemical methods were available for their incorporation into glycofuranosyl conjugates. Herein, we wish to describe the use of the first furanothioglycoligase for the preparation of a great variety of thioaryl derivatives with moderate to excellent yields. Of great interest, a stable 1-thioimidoyl arabinofuranose, classically used in chemical glycosylation, was able to efficiently act as a donor through an original enzymatic remote activation mechanism. Study of the chemical structure as well as the nucleophilicity of the thiol allowed us to optimize this biocatalyzed process. As a consequence, this mutated enzyme constitutes an original, mild and eco-friendly method of thioligation.
    硫代糖苷键在生物分子中至关重要,因为它们的结合可以产生更稳定的糖模拟物,并具有潜在的药物活性。到目前为止,只有化学方法可将其掺入呋喃糖基缀合物中。在此,我们希望描述第一种呋喃硫代糖连接酶用于以中等至优异的产率制备多种硫代芳基衍生物的用途。令人非常感兴趣的是,传统上用于化学糖基化的稳定的1-硫代亚氨基阿拉伯呋喃糖能够通过原始的酶促远程激活机制有效地充当供体。对硫醇化学结构和亲核性的研究使我们能够优化这种生物催化过程。因此,这种突变酶构成了一种原始、温和且环保的硫连接方法。

    N alpha-tert-Butoxycarbonyl-L-trans-4-hydroxyproline allyl ester (Boc-Hyp-OAII) was glycosylated with 2,3,5-tri-O-benzyl-L-arabinose p-cresylthioglycoside in 60% yield with 4:1 beta:alpha stereoselectivity. Deprotection of N- and C-terminii independently gave a prolyl amine and prolyl carboxylate respectively that were coupled under standard conditions with 1-[bis-(dimethylamino)methylene]-1H-1,2,3-triazolo-[4,5,b]-pyridininium hexafluorophosphate 3-oxide (N-HATU) to give the dimer 1 in 46% yield. These results represent the first steps toward the production of homogeneous oligomers to determine the minimal epitope of the Art v 1 allergen.
