    摘要:
    这项工作是一项结构-活性关系研究,研究了碳水化合物底物中的负电荷的性质和数量对β- N-乙酰基己糖胺酶的亲和力以及对自然杀伤细胞的刺激的影响。它描述了产生可用于免疫活化的新糖苷的合成方法。具体来说,我们对六种C-6修饰的β- N-乙酰基己糖胺(醛,尿酸盐,6- O-硫酸盐,6- O-磷酸盐)作为裂解和糖基化底物的能力进行了透彻的研究。 β‐ N来自各种来源的乙酰乙酰氨基葡糖苷酶。在合成反应中以高收率制备了带有一个或两个(负)电荷基团的四种新型二糖。令人惊讶的是6 O磷酸化的底物尽管被该系列中的多种酶切割,但在转糖基化反应中既不作为供体也不作为受体。湿法实验的结果得到了来自筛选的两种代表性酶的活性位点底物的分子模型的支持。检查了所有十种制备的化合物的免疫活性,即它们是天然杀伤(NK)细胞的两个激活受体NKR-P1和CD69的配体,包括分离的蛋白质和全细胞。硫酸二糖尤其可以作为NK细胞非常有效

    摘要:
    硫酸化在自然界中广泛存在,在调节生物功能中发挥着重要作用。微生物开发的获取硫酸化寡糖作为营养源的策略之一是产生 6-sulfoGlcNAcase,以选择性地从目标寡糖中释放 6-sulfoGlcNAc。迄今为止,所有已鉴定的 6-sulfoGlcNAcases 均属于 β-氨基己糖苷酶 GH20 大家族。在这里,我们鉴定并表征了来自肺炎链球菌TIGR4 的一种新的、高度特异性的非 GH20 6-sulfoGlcNAcase,Sp_0475,其对 N-乙酰基-β- D-葡萄糖胺-6-硫酸盐底物的偏好比非硫酸盐版本高110,000 倍以上。Sp_0475 与 GH20 酶和新形成的 GH163 家族具有遥远的序列同源性。然而,它们之间的序列相似性足够低,以至于 Sp_0475 被指定为新糖苷水解酶家族 GH185 的创始成员。通过将定点诱变的结果与机制研究和生物信息学相结合,我们深入了解了 Sp_0475

  • Scope of the DMC mediated glycosylation of unprotected sugars with phenols in aqueous solution
    作者:Xin Qiu、Antony J. Fairbanks
    DOI:10.1039/d0ob01727b
    日期:——
    sugars in aqueous solution using 2-chloro-1,3-dimethylimidazolinium chloride (DMC) and triethylamine in the presence of para-nitrophenol allows direct stereoselective conversion to the corresponding 1,2-trans para-nitrophenyl glycosides without the need for any protecting groups. The reaction is applicable to sulfated and phosphorylated sugars, but not to ketoses or uronic acids or their derivatives
    在对硝基苯酚存在下,使用 2-氯-1,3-二甲基咪唑啉 (DMC) 和三乙胺在水溶液中活化还原糖,可以直接立体选择性转化为相应的 1,2-反式对硝基苯基糖苷,而无需任何保护基团。该反应适用于硫酸化和磷酸化的糖,但不适用于酮糖或糖醛酸或其衍生物。当应用于其他酚类时,发现产物产率取决于 p K a添加的苯酚,并且该方法不太广泛适用于2-乙酰氨基糖。对于 2-乙酰氨基底物,另一种方法是预先形成糖基恶唑啉,将反应混合物冷冻干燥,然后粗产物与添加的苯酚在极性非质子溶剂系统中与微波辐射反应证明是一种有用的简化.

    Biological activity of N-acetyl-6-SUIfO-beta-D-glucosaminides (6-sulfo-GlcNAc 1) having a structural homology to N-acetylneuraminic acid (Neu5Ac 2) and 2-deoxy-2,3-dehydro-N-acetylneuraminic acid (Neu5Ac2en 3) was examined in terms of inhibitory activity against influenza virus sialidase (influenza, A/Memphis/l/71 H3N2). pNP 6-Sulfo-GlcNAc la was proved to show substantial activity to inhibit the virus sialidaSe IC50 2.8 mM), though p-nitrophenyl (pNP) GlcNAc without 6-sulfo group and pNP 6-sulfo-GlcNH(3)(+) 1b without 2-NHAc showed little activity IC50 > 50 mM). The activity was enhanced nearly 100-fold when the pNP group of la was converted to p-acetamidophenyl one 5 (IC50 = 30 muM) or replaced with 1-naphthyl 6 IC50 = 10 muM) or n-propyl one 8 (IC50 = 11 muM) (C) 2004 Elsevier Ltd.

  • Substrate specificity of N-acetylhexosaminidase from Aspergillus oryzae to artificial glycosyl acceptors having various substituents at the reducing ends
    作者:Makoto Ogata、Xiaoxiong Zeng、Taichi Usui、Hirotaka Uzawa
    DOI:10.1016/j.carres.2006.11.004
    日期:2007.1
    The substrate specificity of N-acetylhexosaminidase (E.C. 3.2.1.51) from Aspergillus oryzae was examined using p-nitrophenyl 6-O-sulfo-N-acetyl-beta-D-glucosaminide (6-O-sulfo-GlcNAc-O-pNP) as the glycosyl donor and a series of beta-D-glucopyranosides and N-acetyl-beta-D-glucosaminides with variable aglycons at the anomeric positions as the acceptors. When beta-D-glucopyranosides with methyl (CH3) allyl (CH2CH=CH2), and phenyl (C6H5) groups at the reducing end were used as the acceptors, this enzyme transferred the 6-O-sulfo-GlcNAc moiety in the donor to the location of O-4 in these glycosyl acceptors with a high regioselectivity, producing the corresponding 6-O-sulfo-N-acetylglucosaminyl beta-D-glucopyranosides. However, beta-D-glucopyranose lacking aglycon was a poor substrate for transglycosylation. This A. oryzae enzyme could also accept various N-acetyl-beta-D-glucosaminides carrying hydroxyl (OH), methyl (CH3) propyl (CH2CH2CH3), allyl (CH2CH=CH2) and p-nitrophenyl (PNP; C6H4-NO2) groups at their aglycons, yielding 6-O-sulfo-N-acetylglucosaminyl-beta(1 -> 4)-disaccharide products.
