  Branched aminoglycosides: Biochemical studies and antibacterial activity of neomycin B derivatives

  摘要：

  The C5"-OH group in neomycin B was glycosylated with a variety of mono- and di-saccharides to probe the effect of introduction of additional binding elements on antibacterial activity and interaction with the aminoglycosides modifying enzyme APH(3')-IIIa. The designed structures show antibacterial activity superior to that of neomycin B against pathogenic and resistant strains, while in parallel they demonstrate poor substrate activity with APH(3')IIIa.

  从D-葡萄糖到具有生物活性的L-己糖衍生物：合成α-L-异糖醛酸酶荧光检测剂以及博来霉素A2和硫酸乙酰肝素的二糖部分。

  摘要：

  描述了一种从D-葡萄糖合成生物有效且稀有的L-己糖衍生物的新颖便捷的途径。通过两个步骤有效地将双丙酮-α-D-葡萄糖（14）转化为1,2：3,5-二-O-异亚丙基-β-L-异呋喃糖（19）。化合物19的正交异亚丙基重排导致1,2：5,6-二-O-异亚丙基-β-L-idofuranose（27），其在C3位置进行区域选择性差向异构化，从而得到L-talo-和3-官能化的L-氨基呋喃糖基衍生物。化合物19在酸性条件下的水解以优异的收率提供了1,6-脱水β-L-吡喃葡萄糖（35），成功地将其转化为相应的L-allo，L-altro，L-gulo和L-ido衍生物通过区域选择性苄基化，苯甲酰化，三氟甲磺酸酯化和亲核取代是关键步骤。

Clearly, DOIS recognizes the G-6-P substrate through specific hydrogen-bonding interactions, i.e., through a hydrogen-donating group for C-2 and an accepting group for C-3 of the substrate.

  在临床上重要的氨基环醇抗生素的2-deoxystreptamine糖苷生物合成中的关键酶是2-deoxy-scyllo-inosose合酶（DOIS），它将普遍存在的D-葡萄糖6-磷酸酯（G-6-P）转化为特定的碳环2-脱氧鞘氨醇。在底物的所有氧化碳中，C-1，-4，-5和-6直接参与化学转化。为了深入了解C-2和C-3羟基，2-脱氧-2-氟，3-脱氧-3-氟，2-氨基-2-脱氧和3-氨基-3的作用-脱氧D-葡萄糖6-磷酸酯（2-FG-6-P，3-FG-6-P，2-NH（2）-G-6-P和3-NH（2）-G-6 -P）分别作为探针进行DOIS反应，因为氟取代基通常充当氢键受体，而生理上衍生自氨基的铵官能团作为氢键供体。在测试的那些当中，2-FG-6-P和3-NH（2）-G-6-P被DOIS用作底物，并分别转化为相应的脱氧氟-和氨基脱氧-鞘氨醇。相反，3-FG-6-P和2-NH（2）-G-6

  We introduce a new use of sulfonyl fluoride as a bifunctional reagent that facilitates the one-step deoxy-diversification of complex alcohol libraries. Our reaction design features a Sulfur(VI) Fluoride Exchange (SuFEx) mediated activation of alcohols and fluoride-induced activation of silicon-bound nucleophiles. This method enables the direct conversion of alcoholic C–O bonds in complex molecules into

  A series of 10 new carbohydrate-substituted bipyridines were prepared from 2,2'-bipyridine-3,3'-dicarboxylic acid, itself easily available from ortho-phenanthroline. As a preliminary exploration of their use as chiral ligands, Cu(II)-catalysed asymmetric electrophilic fluorination of model beta-ketoesters using these simple and easily accessible chiral bipyridines was studied. Only modest enantioselectivity was observed in this reaction, although the ee was in a similar range as those provided by known and more elaborate ligands. (C) 2009 Elsevier Ltd. All rights reserved.
