    摘要:
    糖氨基酸 (SAA) 被设计和合成为新的非肽肽模拟物,利用碳水化合物作为肽构建块。它们代表带有氨基和羧基官能团的类糖环结构,并且由于它们在刚性吡喃糖环中的不同取代模式,因此对肽的骨架具有特定的构象影响。已经合成了五种不同的 SAA(SAA1α、SAA1β、SAA2、SAA3 和 SAA4),它们显示出限制线性骨架构象或不同转角结构的能力。涉及 SAA 的线性和环状肽已在溶液中以及通过固相合成制备。SAA1α 和 SAA2 被整合到两个线性亮氨酸-脑啡肽类似物中,取代了天然的 Gly-Gly 二肽。NMR 研究为碳水化合物部分的构象诱导作用提供了证据。SAA2 和 SAA3 已被置于生长抑素的环状六肽类似物中;SAA4 被掺入模型肽中。的构造...

  • Naplephos through the Looking-Glass: Chiral Bis(phosphanylamides) Based on β-1,2-D-Glucodiamine and Their Application in Enantioselective Allylic Substitutions

    The straightforward design of a new library of chiral ligands (elpanphos) based on β-1,2-D-glucodiamine is described, which represents the enantiomeric counterpart of the naplephos library. In this guise, two representative ligands have been successfully applied in the Pd-catalyzed desymmetrization of meso-cyclopent-2-ene-1,4-diol, which leads to the expected enantiomer within short times and with

  • Poly(methyl 6-acryloyl-β-<scp>d</scp>-glucosaminoside) as a Cationic Glycomimetic of Chitosan
    作者:Walter T. Liau、Andrea M. Kasko
    DOI:10.1021/acs.biomac.7b01191
    日期:2017.12.11
    Chitosan, a cationic polysaccharide derived from one of the most abundant natural polymers, chitin, has been investigated extensively for its antimicrobial properties. However, it suffers from the inherent drawbacks of natural products such as batch-to-batch variability, limited supply, contamination, and potential adverse reaction. Additionally, its solubility depends on the degree of deacetylation and pH, as it is only soluble under acidic conditions. As an alternative to chitosan, we synthesized the protected cationic glycomimetic monomer methyl N-Fmoc-6-acryloyl-β-d-glucosaminoside from glucosamine. This monomer retains structural features critical to recapitulating the properties of the chitosan repeat unit, namely, the pKa of the protonated amine. We optimized the free radical polymerization of methyl N-Fmoc-6-acryloyl-β-d-glucosaminoside and fractionated the resultant poly(methyl N-Fmoc-6-acryloyl-β-d-glucosaminoside) to obtain a range of molecular weights. Following Fmoc deprotection, the cationic glycopolymers retained 95% of their expected amine content by mass and exhibited a pKa of 6.61. Poly(methyl 6-acryloyl-β-d-glucosaminoside) mimicked the molecular weight-dependent bacterial inhibitory property of chitosan in acidic solutions. Importantly, poly(methyl 6-acryloyl-β-d-glucosaminoside) remained soluble at elevated pH (conditions under which chitosan is insoluble) and maintained its antibacterial activity. Mammalian cell viability in the presence of poly(methyl 6-acryloyl-β-d-glucosaminoside) at acidic pH is good, although somewhat lower than viability in the presence of chitosan. No cytotoxic effect was observed at neutral pH. These results demonstrate that poly(methyl 6-acryloyl-β-d-glucosaminoside) is not only a suitable biomimetic for chitosan, but that it can be utilized as an antibacterial agent in a broader range of biologically relevant pHs.
    壳聚糖是一种从几丁质(最丰富的天然多糖之一)中提取的阳离子多糖,因其抗菌特性而受到广泛研究。然而,它存在天然产品的固有缺陷,如批次间差异、供应有限、污染以及潜在的不良反应。此外,其溶解性依赖于脱乙酰度和pH值,只有在酸性条件下才能溶解。作为壳聚糖的替代品,我们合成了受保护的阳离子糖类模拟单体甲基N-Fmoc-6-丙烯酰基-β-D-葡萄糖胺苷酸。该单体保留了重现壳聚糖重复单元特性的关键结构特征,即质子化胺的pKa值。我们优化了甲基N-Fmoc-6-丙烯酰基-β-D-葡萄糖胺苷酸的自由基聚合反应,并将所得聚合物进行了分子量分级。在Fmoc脱保护后,这些阳离子糖类聚合物保留了其预期胺含量95%的质量,并展现出6.61的pKa值。聚甲基6-丙烯酰基-β-D-葡萄糖胺苷酸在酸性溶液中模拟了壳聚糖与分子量相关的细菌抑制特性。重要的是,在升高的pH值条件下(壳聚糖不溶于此条件),聚甲基6-丙烯酰基-β-D-葡萄糖胺苷酸仍然保持溶解性并维持其抗菌活性。在使用酸性pH值的聚甲基6-丙烯酰基-β-D-葡萄糖胺苷酸时,哺乳动物细胞的存活率良好,尽管略低于使用壳聚糖时的存活率。在中性pH下未观察到细胞毒性效应。这些结果表明,聚甲基6-丙烯酰基-β-D-葡萄糖胺苷酸不仅是一个合适的壳聚糖生物模拟物,而且可以在更广泛的与生物相关的pH范围内作为抗菌剂使用。

    family of ligands, which represents a subset of the elpaN-type library based on d-glucose, is described. The ligands are structural analogs of the privileged bis(pyridine-2-carboxamides) derived from trans-1,2-diaminocyclohexane, and differ for the type of substitution in the coordinating functions present in positions 1 and 2.

    O-GlcNAcylation或O-GlcNAc修饰是负责基本细胞过程的几种蛋白质的翻译后修饰。O-GlcNAc途径的失调与多种疾病的病因有关,例如神经退行性和心血管疾病,2型糖尿病和癌症。O-GlcNAcase(OGA)催化从修饰的蛋白质中去除O-GlcNAc,并且已经合成了几种基于碳水化合物的OGA抑制剂以了解O-GlcNAc修饰的蛋白质在生理和病理条件下的作用。但是,许多抑制剂对溶酶体己糖胺酶A和溶酶B缺乏对OGA的选择性。针对OGA的选择性抑制,我们在此提出了十二种新颖的喃糖苷衍生物的合成方法,这些衍生物探索了GlcNAc 2-乙酰胺基的生物等位取代作用,4-二取代的1,2,3-三唑环,带有各种不同形状的中心链。通过糖叠氮化物与不同末端炔烃之间的“(I)催化的叠氮化物/炔环加成反应”(CuAAC)反应可以容易地制备化合物。初步的Western Blot分析和进一步的抑制性测定证明化合物6a(IC50
