  • Chemoenzymatic glycan-selective remodeling of a therapeutic lysosomal enzyme with high-affinity M6P-glycan ligands. Enzyme substrate specificity is the name of the game

    therapeutic lysosomal enzymes is a challenging task. We report here the chemical synthesis of truncated M6P-glycan oxazolines and their use for enzymatic glycan remodeling of recombinant human acid α-glucosidase (rhGAA), an enzyme used for treatment of Pompe disease which is a disorder caused by a deficiency of the glycogen-degrading lysosomal enzyme. Structure–activity relationship studies identified
    用 6-磷酸甘露糖 (M6P) 聚糖配体对治疗性溶酶体酶进行功能化是增强阳离子非依赖性 M6P 受体 (CI-MPR) 介导的细胞摄取的主要策略,从而提高酶的整体治疗功效。然而,最小的高亲和力 M6P 含N-聚糖配体仍有待鉴定,它们与治疗性溶酶体酶的有效和位点选择性缀合是一项具有挑战性的任务。我们在此报告截短的 M6P-聚糖恶唑啉的化学合成及其在重组人酸性 α-葡萄糖苷酶 (rhGAA) 的酶促聚糖重塑中的应用,该酶用于治疗庞贝病,这是一种由糖原缺乏引起的疾病-降解溶酶体酶。构效关系研究确定 M6P 四糖恶唑啉是酶促转糖基化的最小底物,可产生 CI-MPR 的高亲和力 M6P 聚糖配体。利用内切糖苷酶 Endo-A 和 Endo-F3 的底物特异性,我们发现 Endo-A 和 Endo-F3 可以有效地去糖基化各自的高甘露糖和复合型rhGAA 中的N-聚糖和位点选择性地将合成的 M6P N-聚糖转移到去糖基化的
  • Studies on the substrate specificity of a GDP-mannose pyrophosphorylase from <i>Salmonella enterica</i>
    作者:Lu Zou、Ruixiang Blake Zheng、Todd L Lowary
    DOI:10.3762/bjoc.8.136
    日期:——

    A series of methoxy and deoxy derivatives of mannopyranose-1-phosphate (Manp-1P) were chemically synthesized, and their ability to be converted into the corresponding guanosine diphosphate mannopyranose (GDP-Manp) analogues by a pyrophosphorylase (GDP-ManPP) from Salmonella enterica was studied. Evaluation of methoxy analogues demonstrated that GDP-ManPP is intolerant of bulky substituents at the C-2, C-3, and C-4 positions, in turn suggesting that these positions are buried inside the enzyme active site. Additionally, both the 6-methoxy and 6-deoxy Manp-1P derivatives are good or moderate substrates for GDP-ManPP, thus indicating that the C-6 hydroxy group of the Manp-1P substrate is not required for binding to the enzyme. When taken into consideration with other previously published work, it appears that this enzyme has potential utility for the chemoenzymatic synthesis of GDP-Manp analogues, which are useful probes for studying enzymes that employ this sugar nucleotide as a substrate.

    一系列甲氧基和去氧衍生物的甘霖糖吡喷酸酯(Manp-1P)经化学合成,研究了它们通过一种来自沙门氏菌(Salmonella enterica)的焦磷酸化酶(GDP-ManPP)能否转化为相应的鸟苷二磷酸甘霖糖(GDP-Manp)类似物的能力。对甲氧基类似物的评价表明,GDP-ManPP对C-2、C-3和C-4位置的庞大取代基不耐受,进而暗示这些位置被埋藏在酶活性位点内部。此外,6-甲氧基和6-去氧 Manp-1P 衍生物均是GDP-ManPP的良好或中等底物,因此表明 Manp-1P 底物的C-6 羟基不是与酶结合所必需的。综合考虑先前发表的其他研究成果,这种酶似乎具有潜在的用途,可用于化酶合成 GDP-Manp 类似物,这些类似物是用于研究以这种糖核苷酸为底物的酶的有用探针。
  • A Glycosylation Protocol Based on Activation of Glycosyl 2-Pyridyl Sulfones with Samarium Triflate
    作者:Grace X. Chang、Todd L. Lowary
    DOI:10.1021/ol005579k
    日期:2000.6.1
    [reaction--see text] Reaction of glycosyl 2-pridyl sulfones (e.g.,2) with alcohols and samarium(III) triflate affords glycosides in moderate to excellent yields. Benzylated sulfones can be activated in preference to their benzoylated counterparts, and the methodology has been used to prepare di- and trisaccharides containing both furanose and pyranose residues. Thioglycosides do not react under these
    [反应-见正文]糖基2-戊基砜(例如2)与醇和三氟甲磺酸sa的反应可得到中等至极好的糖苷收率。可以优先活化苯甲酰化的砜,而不是苯甲酰化的对应物,并且该方法已用于制备同时含有呋喃糖和吡喃糖残基的二糖和三糖。硫糖苷在这些条件下不反应,并且砜对通常用于活化硫糖苷的N-碘琥珀酰亚胺/三氟甲磺酸银助催化剂系统呈惰性。这种选择性允许通过正交糖基化方案有效地制备寡糖。
  • Novel ester linked glycosyl amino acids: convenient building blocks for the synthesis of glycopeptide libraries
    作者:Richard J. Tennant-Eyles、Antony J. Fairbanks

    日期:1999.1
    The completely orthogonally protected aspartic acid derivative FmocAsp(OBn)OtBu is readily synthesized on a large scale. Deprotection of the β-carboxylic acid allows coupling to various sugar derivatives via free hydroxyl groups to produce novel glycosyl amino acids. Subsequent deprotection of either the α-acid or nitrogen is achieved cleanly to allow elaboration into an oligopeptide, whilst selective
    完全正交保护的天冬氨酸衍生物FmocAsp(OBn)O t Bu易于大规模合成。β-羧酸的去保护基团允许通过游离羟基与各种糖衍生物偶联以产生新的糖基氨基酸。干净地实现随后的α-酸或氮的脱保护,以使其能够精加工成寡肽,同时也易于实现对PMB保护的糖羟基的选择性脱保护。这样的新颖的糖基氨基酸构件可以用于新颖的糖肽文库的组合合成。
  • Synthesis of inositol phosphoglycans containing thiol-terminated spacers for efficient coupling to maleimide functionalized solid phases or proteins
    作者:Jan Lindberg、Peter Strålfors、Peter Konradsson
    DOI:10.1016/s0040-4020(02)00359-9
    日期:2002.5
    The synthesis of inositol phosphoglycans (IPGs), analogous to second messengers of insulin, to provide a small targeted library of compounds is described. These derivatives contain the glucosamine(α1–6)myo-inositol 1,2-cyclic phosphate motif. A thiol-terminated spacer was introduced, for their immobilization, by a radical elongation of an allyl ether with benzyl mercaptane.
