  包含胰岛素类似物分子的胰岛素共轭物，与至少一个双齿配体连接物共价连接，每个配体独立连接到一个含有糖类的配体，并且连接物中至少一个配体的糖类是富马醇。这些胰岛素共轭物显示出对糖类（如葡萄糖或α-甲基甘露糖）的体内浓度响应的药代动力学（PK）和/或药效动力学（PD）特性，即使在向需要者施用时，也无需外源多价糖类结合分子（如Con A）。

• Total Synthesis of Belizentrin Methyl Ester: Report on a Likely Conquest
  作者：Felix Anderl、Sylvester Größl、Conny Wirtz、Alois Fürstner

  DOI：10.1002/anie.201805125

  日期：2018.8.13

  The assigned structure of the dinoflagellate‐derived toxin belizentrin was prepared by total synthesis in form of the corresponding methyl ester for stability reasons. The successful route features an unusual solution for the preparation of a recalcitrant ylide on a C‐glycosidic segment; moreover, it involves an asymmetric hetero‐Diels–Alder reaction en route to the tertiary hemiacetal substructure

  由于稳定性原因，通过全合成以相应甲酯的形式制备了源自鞭毛鞭毛贝利恩特林的毒素的指定结构。成功的途径是在C-糖苷段上制备顽固性叶立德的一种不寻常的解决方案。此外，它还涉及到第三半缩醛亚结构的不对称杂Diels-Alder反应，两个精心构建的模块的Negishi交叉偶联以及基于螺内酯分子内氨解的大环化。改性的Kocienski烯烃化反应最终使多元醇侧链连接到大环上，尽管这种转化面临着这种多不饱和目标化合物的异常碱基敏感性。

  Insulin conjugates comprising an insulin molecule covalently attached to at least one bi-dentate linker having two arms, each arm independently attached to a ligand comprising a saccharide and wherein the saccharide for at least one ligand of the linker is fucose are disclosed. The insulin conjugates display a pharmacokinetic (PK) and/or pharmacodynamic (PD) profile that is responsive to the systemic concentrations of a saccharide such as glucose or alpha-methylmannose even when administered to a subject in need thereof in the absence of an exogenous multivalent saccharide-binding molecule such as Con A.

• The Synthesis of Some Epoxyalkyl b-C-Glycosides as Potential Inhibitors of b-Glucan Hydrolases

  The treatment of tetra-O-benzyl-D-glucono-1,5-lactone with various alkenylmagnesium halides gave the intermediate lactols which, upon reduction (Et3SiH/BF3) and protecting group manipulation, yielded alkenyl tetra-O-acetyl-β-D-C-glucopyranosides in good yield. These β-D-C-glucosides were precursors of the epoxyalkyl β-D-C-glucopyranosides, themselves putative inhibitors of b-glucan hydrolases. Similar additions of Grignard reagents to per-benzylated cellobionolactone were not as successful in yielding epoxyalkyl β-C-cellobiosides. The addition of Grignard reagents to 1,2-anhydro-3,4,6-tri-O-benzyl-α-D- glucose offers a viable alternative route to the prop-2-enyl β-D-C-glucoside, but not to the but-3-enyl and pent-4-enyl counterparts. Likewise, the addition of Grignard reagents to a 1,2-anhydro cellobiose gave disappointing results. Preliminary results are reported for a novel approach to alkenyl β-D-C-glucosides by the alkylation of nitromethyl β-D-C-glucosides.

  Thiol-ene click chemistry has been applied for obtaining sulfonamide carbonic anhydrase (CA, EC 4.2.1.1) inhibitors incorporating sugar moieties. Most of these new compounds were moderate CA I inhibitors, effective CA II inhibitors, and low nanomolar/subnanomolar inhibitors of the tumor-associated isoforms CA IX and XII.
