    摘要:
    我们已经研究了甾体糖苷作为胆固醇吸收抑制剂的作用,该抑制剂通过未知的机制起作用。该程序的主要成分是tigogenin纤维二糖苷(1,tiqueside),它是一种弱抑制剂(ED50 = 60 mg / kg),在急性仓鼠胆固醇吸收试验中测得。对该分子类固醇部分的修饰导致发现了11-酮维他命原纤维二糖苷(5,巴马苷),其ED50为2 mg / kg。用其他糖代替纤维二糖不能提供更有效的类似物。然而,通过修饰纤维二糖上的羟基实现了效力的大的提高。这种策略最终导致11-酮基黄酮生成素(51)的4“,6”-双[(2-氟苯基)氨基甲酰基]-β-D-纤维二糖基衍生物在仓鼠试验中的ED50为0.025 mg / kg,

    Probing acceptor specificity in the glycogen synthase reaction with polymer-bound oligosaccharides
    摘要:
    Polymers having maltose and maltotriose side-chains were synthesized by attaching 4-carboxy-2-nitrobenzyl 4-O-alpha-D-glucopyranosyl-beta-D-glucopyranoside or 4-carboxy-2-nitrobenzyl O-alpha-D-glucopyranosyl-(1----4)-O-alpha-D-glucopyranosyl-O-beta-D- glucopyranoside, respectively, to aminoethyl-substituted polyacrylamide gel beads. Subsequently, the two polymers, and analogous polymers having D-glucose and cellobiose side-chains, served in a comparative study as acceptors in the glycogen synthase (UDP-D-glucose: glycogen 4-alpha-glucosyltransferase, EC 2.4.1.11) reaction. Highest transfer (4.2%) was observed for the polymer bearing maltotriose groups. The bound saccharides were then removed by irradiation (greater than 320 nm), and examination of them demonstrated that alpha-D-glucosyl oligomerization in the glycogen synthase reaction had occurred.

  • Photoredox-Catalyzed Stereoselective Synthesis of <i>C</i>-Nucleoside Analogues from Glycosyl Bromides and Heteroarenes
    作者:Liwen Xia、Wenjing Fan、Xiang-Ai Yuan、Shouyun Yu
    DOI:10.1021/acscatal.1c02088
    日期:2021.8.6
    C-nucleosides, analogues of nucleosides by replacing a C–N glycosidic bond with a C–C bond, are potential anticancer or antiviral agents. Synthesis of C-nucleoside analogues enabled by photoredox-catalyzed radical coupling of glycosyl bromides with nonfunctionalized heteroarenes has been described. This strategy features readily available starting materials, mild conditions, good functional group tolerance
    C-核苷是用 C-C 键取代 C-N 糖苷键的核苷类似物,是潜在的抗癌或抗病毒剂。已经描述了通过糖基化物与非官能化杂芳烃的光氧化还原催化自由基偶联实现的C-核苷类似物的合成。该策略具有容易获得的起始材料、温和的条件、良好的官能团耐受性以及位点和立体选择性(α-构型)。多种单糖(d-来苏糖、d-核糖、l-阿拉伯糖、d-葡萄糖、d-甘露糖、d-葡糖苷酸和d-岩藻糖)、二糖(乳糖蜜二糖麦芽糖)和多糖麦芽三糖)可以与一系列非功能化的杂芳烃偶联,如嘌呤苯并噻唑噻唑吡啶苯并恶唑苯并咪唑咪唑吡啶菲啶生物学上重要的分子,如茶碱、泛昔洛韦呋喃核糖苷和腺嘌呤,可以使用这种方法直接通过 C-C 键进行糖基化。位点和立体选择性可以通过密度泛函理论 (DFT) 计算进行合理化和预测。

    A short route to phenyl 1-thio-β-maltotrioside derived building blocks and their use for the synthesis of the branched nonasaccharide, 6'''-α-maltotriosyl-maltohexaose, is described. Instead of using glucose and maltose as starting materials, maltotriose was used and synthetically manipulated in a well designed strategy to obtain phenyl O-(2,3,4,6-tetra-O-benzyl-α-D-glucopyranosyl)-(1→4)-O-(2,3,6-

    (OA) was discovered as a mild influenza hemagglutinin (HA) inhibitor. Herein, as a further study, we report the preparation of a series of OA-saccharide conjugates via the CuAAC reaction, and the anti-influenza activity of these compounds was evaluated in vitro. Among them, compound 11b, an OA-glucose conjugate, showed a significantly increased anti-influenza activity with an IC50 of 5.47 μM, and no
    进入抑制剂的开发是抑制流感病毒的新兴方法。在我们之前的研究中,齐墩果酸(OA)被发现是一种轻度的流感血凝素(HA)抑制剂。在本文中,作为进一步的研究,我们报道了通过CuAAC反应制备一系列OA-糖缀合物的方法,并在体外评估了这些化合物的抗流感活性。其中,OA-葡萄糖偶联物化合物11b显示出显着提高的抗流感活性,IC50为5.47μM,在100μM下未观察到对MDCK细胞的明显细胞毒性作用。血凝抑制试验和对接实验表明11b可能通过作用于HA蛋白而干扰流感病毒的感染。广谱抗流感实验显示11b对5种不同菌株具有强大的效力,包括甲型和乙型流感病毒,IC50值处于低微摩尔平。总体而言,该发现进一步扩展了OA-糖缀合物在抗流感病毒药物设计中的用途。

    A general and efficient protocol for the palladium‐catalyzed functionalization of mono‐ and polyglycosyl thiols by using the palladacycle precatalyst G3‐XantPhos was developed. The CS bond‐forming reaction was achieved rapidly at room temperature with various functionalized (hetero)aryl‐, alkenyl‐, and alkynyl halides. The functional group tolerance on the electrophilic partner is typically high and
