    名称:
    Iodonium ion-assisted synthesis of a haptenic tetrasaccharide fragment corresponding to the inner cell-wall glycopeptidolipid of Mycobacterium avium serotype 4
    摘要:
    Condensation of ethyl 2,4-di-O-benzoyl-1-thio-alpha-L-rhamnopyranoside with ethyl 3-O-benzyl-4-O-chloroacetyl-2-O-methyl-1-thio-beta-L-fucopyranoside in the presence of iodonium di-sym-collidine perchlorate afforded exclusively ethyl 2,4-di-O-benzoyl-3-O-(3-O-benzyl-4-O-chloroacetyl-2-O-methyl-alpha-L-fucopyranosyl)-1-thio-alpha-L-rhamnopyranoside. This disaccharide derivative was extended at C-1 with 3-benzyloxycarbonylaminopropyl 6-deoxy-3,4-O-isopropylidene-alpha-L-talopyranoside, using N-iodosuccinimide and triflic acid as the catalyst, to furnish 3-benzyloxycarbonylaminopropyl 6-deoxy-2-O[2,4-di-O-benzoyl-3-O-(3-O-benzyl-4-O-chloroacetyl-2-O-methyl-alpha-L-fucopyranosyl)-alpha-L-rhamnopyranosyl]-3,4-0-isopropylidene-alpha-L-talopyranoside (20). Selective removal of the chloroacetyl group from 20, followed by condensation with ethyl 2,3-di-O-benzoyl-4-O-methyl-1-thio-alpha-L-rhamnopyranoside in the presence of the same thiophilic promoter, yielded a fully protected tetrasaccharide derivative. Deprotection of the latter gave the target compound 3-aminopropyl 6-deoxy-2-O-{3-O-[2-O-methyl-(4-O-methyl-alpha-L-rhamnopyranosyl)-alpha-L-fucopyranosyl]-alpha-L-rhamnopyranosyl}alpha-L-talopyranoside (1).

    重组血型A和B糖基转移酶的修饰受体的合成和酶促评估。
    摘要:
    二糖α-L-Fucp-(1-> 2)-β-D-Galp-(1-> O)-辛基(1)是人血A和B组糖基转移酶的受体。化学合成了1的七个类似物,其中包含Fuc残基的脱氧,甲氧基和阿拉伯糖基修饰,并在放射性酶分析中进行了动力学评估。两种酶都耐受岩藻糖残基上3'-OH的修饰。发现2'-OH是这些酶识别受体的关键。阿拉伯糖衍生物被A转移酶(Km为200 microM)识别为受体,但未被B转移酶识别,并且是第一个能够区分两种酶活性的合成受体。

    6-dideoxy- l - lyxo -hexopyranosyl (‘4-deoxy- l -rhamnosyl’) and 4-deoxy-4-fluoro- l -rhamnosyl monosaccharide residues. The preparation of the deoxyfluororhamnose was not straightforward, and revealed some unexpected behavior of the diethylaminosulfur trifluoride (DAST) reagent. The new glycosyl donors were used to synthesize two analogs of the mycobacterial arabinogalactan linkage disaccharide →4)-α- l
    摘要我们为4,6-二脱氧-1-Lyxo-己喃糖基('4-deoxy-1-rhamnosyl')和4-deoxy-4-fluoro-1-rhamnosyl单糖残基制备了代糖苷供体。脱氧鼠李糖的制备并不简单,并且揭示了二乙基基三DAST)试剂的某些出乎意料的行为。新的糖基供体用于合成分枝杆菌阿拉伯半乳聚糖键合二糖→4)-α-1-Rha-(1→3)-α-d-GlcNAc的两个类似物。这些类似物是分枝杆菌细胞壁构建早期阶段所涉及的酶的潜在抑制剂家族的原型。
  • Sulfuric acid immobilized on silica: an efficient promoter for one-pot acetalation–acetylation of sugar derivatives
    作者:Balaram Mukhopadhyay
    DOI:10.1016/j.tetlet.2006.04.118
    日期:2006.6
    Sulfuric acid immobilized on silica gel has been used as an efficient and safe alternative promoter for acetalation and subsequent acetylation of sugar glycosides using stoichiometric reagents without work-up. The synthesis of different types of per-O-acetylated acetals/ketals has been achieved from various types of O- and S-glycosides in excellent yields.

    We describe here the synthesis of the allyl Le(a) trisaccharide antigen as well as that of an analogue of the Le(x) trisaccharide antigen, in which the galactose residue has been replaced by a glucose unit. Although successful fucosylations at O-4 of N-acetylglucosamine acceptors have been reported using perbenzylated thioethyl fucosyl donors under MeOTf activation, such conditions led in our case
    我们在这里描述了烯丙基Le(a)三糖抗原以及Le(x)三糖抗原类似物的合成,其中半乳糖残基已被葡萄糖单元取代。尽管已经报道过在MeOTf活化下使用过苄基代乙基岩藻糖基供体在N-4-乙酰葡糖受体的O-4处成功进行岩藻糖基化,但在我们的情况下,这种条件导致我们的受体转化为相应的烷基酰亚胺。确实,在Le(a)类似物的合成中,我们证明了N-乙酰基作为亚酸甲酯的暂时保护对于在O-4处岩藻糖基化是有利的。相比之下,我们在此报告,使用过乙酰化的葡萄糖的α-三乙酰亚酸作为供体,在N-4乙酰氨基葡萄糖单糖受体的O-4处进行的糖基化在活化的情况下比过量的BF(3)x OEt(2)产生的产率更高。亚胺酯。因此,我们得出结论,在暂时保护N-乙酰基为亚酸甲酯的情况下,最好通过MeOTf激活氨基葡萄糖上的糖苷供体在糖胺受体的O-4处糖基化,特别是当供体具有高反应性并易于降解时。相反,如果供体和受体可以承受BF(3)x

    The trisaccharide‐Hyp moiety was employed for the preparation of the glycopeptide using microwave‐assisted solid phase peptide synthesis. Enzyme kinetic studies revealed that trisaccharide‐Hyp and trisaccharide‐peptide are poorly recognized by AgtA, indicating the importance of context provided by the native Skp1 protein for engagement with the active site. The trisaccharide‐peptide was a potent immunogen
    Skp1是一种胞质蛋白和核蛋白,最著名的是E3泛素连接酶SCF家族的一个衔接子,为蛋白质的降解标记。双歧杆菌中的Skp1由五糖在特定的羟脯酸(Hyp)残基上进行翻译后修饰,该五糖由Fucα1,2-Galβ-1,3-GlcNAcα核组成,并装饰有两个α-连接的Gal残基。制备了糖肽衍生形式Skp1,以表征介导α-Gal部分添加的α-半乳糖基转移酶(AgtA),并开发出适合追踪细胞中Skp1的三糖同工型的抗体。基于2-甲基(Nap)醚作为永久保护基团的使用,开发了一种合成三糖-Hyp核心的策略,以允许Hyp部分的后期安装。糖基供体和受体反应性的调节对于实现糖基化的高产率和异头选择性至关重要。利用微波辅助固相肽合成法将三糖-Hyp部分用于糖肽的制备。酶动力学研究表明,AgtA无法识别三糖-Hyp和三糖-肽,这表明天然Skp1蛋白提供的与活性位点结合的环境非常重要。三糖肽是一种有效的免疫原,能
