    Synthesis of 6′-acylamido-6′-deoxy-α-d-galactoglycerolipids
    摘要:
    Aminoglycoglycerolipid 1a isolated from an algal extract showed activity against the enzyme Myt1 kinase with an IC50 value of 0.12 mu g/mL. Its analogues, 6'-acylamido-6'-deoxy-alpha-D-galactoglycerolipids (2a-g) were synthesized in an efficient way with high stereoselectivity. The key step was to employ a 4-OAc protecting group of the galactosyl donor 14 as a remote neighboring participation group to give the glycoside with high alpha-anomeric selectivity (alpha:beta = 32:1) in the glycosylation. The preliminary bioactivity screening showed that compound 2g exhibited good inhibition against Myt1 kinase. (C) 2013 Elsevier Ltd. All rights reserved.

    摘要:
    固相合成是一种实用的方法,可以简化大量天然分子制备过程中耗时且常规的纯化步骤;然而,由于缺乏方便的监测方法,研究这些反应很困难。通过将薄层色谱与树脂上的光不稳定接头结合使用,我们开发了一种方便且简单的方法,通过薄层色谱实时监测固相反应。该方法提供了一个用户友好的协议,用于检查固态合成的反应条件。

  • Sensitive and specific enzyme immunoassays for antigenic trisaccharide from Bacillus anthracis spores
    作者:Sandrine G. Y. Dhénin、Vincent Moreau、Marie-Claire Nevers、Christophe Créminon、Florence Djedaïni-Pilard

    A straightforward synthesis of an anthrose-containing trisaccharide derived from Bacillus anthracis was achieved. Antibodies raised against this hapten provide a highly sensitive enzyme immunoassay with a detection limit of 8.5 pmol mL−1. By investigating the specificity of the antibodies obtained using different mono-, di- and trisaccharide synthetic analogues, we demonstrated that the epitope was mainly made up of the methyl group at C-5, the butamido group at C-4 and the hydroxyl at C-3 of the anthrose unit, the other parts of the trisaccharide appearing little involved in the recognition.
    成功实现了一种来源于炭疽杆菌的含炭疽糖的三糖的直接合成。针对这种半抗原产生的抗体提供了高度敏感的酶免疫测定法,其检测限为8.5 pmol mL−1。通过研究使用不同单糖、二糖和三糖合成类似物获得的抗体的特异性,我们证明表位主要由炭疽糖单元中的C-5甲基、C-4丁酰胺基和C-3羟基组成,三糖的其他部分在识别中涉及较少。

    A straightforward synthesis of a derivative of anthrose, the non-reducing terminal fragment of the antigenic tetrasaccharide from Bacillus anthracis, was achieved starting from d-galactose. This hapten is able to induce a highly specific and sensitive immune response in rabbit when attached to a carrier protein.

  • Synthesis and Application of a 2-[(4-Fluorophenyl)-sulfonyl]ethoxy Carbonyl(Fsec) Protected Glycosyl Donor in Carbohydrate Chemistry
    作者:Sara Spjut、Weixing Qian、Mikael Elofsson

    The 2-[(4-fluorophenyl)sulfonyl]ethoxy carbonyl (Fsec) group for protection of hydroxyl groups has been designed, synthesized, and evaluated. Fsec-Cl was readily prepared in 91% yield over three steps and subsequently used to protect 4-fluorobenzyl alcohol in high yield. The Fsec group was cleaved from the resulting model compound under mild basic conditions e.g., 20% piperidine in DMF and was stable under acidic conditions, e.g., neat acetic acid. The Fsec group was used to protect the unreactive 4-OH in a galactose building block that was later used in the synthesis of 6-aminohexyl galabioside.
    已设计、合成并评估了2-[(4-氟苯基)磺酰]乙氧羰基(Fsec)团用于保护羟基。Fsec-Cl在三步反应中以91%的产率轻易制备,并随后用于高产率保护4-氟苯甲醇。所得到的模型化合物在温和碱性条件下(例如,20%哌啶在DMF中)去除了Fsec基团,而在酸性条件下(例如,纯醋酸)则保持稳定。Fsec基团被用于保护在半乳糖构建模块中不反应的4-OH,后者随后用于合成6-氨基己基半乳糖苷。

    orientation of the anomeric glycosidic bond of CCL-34 resulted in a complete loss of activity (β-CCL34). Surprisingly, a change in configuration of the anomeric glycosidic bond in a glucosyl glycolipid is tolerable (CCL-34-S14). Another noteworthy observation is that the activity of a L-fucosyl derived glycolipid (CCL-34-S13) was comparable to that of CCL-34. In sum, this study determines the structural
    通过改变α-GalCer衍生的前导化合物(CCL-34)的脂链长度和糖结构,合理设计了一系列新的不含磷酸基的单糖基糖脂,带有两个脂链),这是一种有效的TLR4激动剂。在稳定表达人TLR4,MD2和CD14(293-hTLR4 / MD2-CD14)的HEK293细胞系中测量了包含60个成员的具有不同脂质链长度的化合物的基于半乳糖基丝氨酸的合成文库的NF-κB活性。结果表明,脂胺和脂肪酸激活TLR4的最佳碳链长度分别为10-11和12。对包含具有各种糖基部分和固定脂链长度的化合物的20元合成基于糖基丝氨酸的脂质文库的评估表明,CCL-34中的半乳糖部分可以被取代葡萄糖而不会丧失活性(CCL-34-S3和CCL-34-S16)。改变CCL-34的异头糖苷键的方向导致活性完全丧失(β-CCL34)。令人惊讶地,糖基糖脂中的异头糖苷键的构型变化是可忍受的(CCL-34-S14)。另一个值得注意的发
