    以神经胺为最佳核心结构的新型氨基糖苷类抗生素的设计和合成:抗生素活性与体外翻译抑制的相关性
    摘要:
    在氨基糖苷类抗生素中发现的假二糖核心的结构和活性是用一系列合成类似物探测的,其中氨基的位置在吡喃葡萄糖环周围发生变化。根据体外 RNA 结合和抗生素活性的测定,天然存在的结构 neamine 是该系列中最好的。有了这个结果,neamine 被用作合成新抗生素的共同核心结构,评估其与大肠杆菌 16S A 位点核糖体 RNA 模型的结合、体外蛋白质合成抑制和抗生素活性。RNA结合的分析揭示了RNA结合的相对亲和力和特异性与抗菌功效之间的一些相关性。然而,相关性不是线性的。这一结果促使我们开发了体外翻译试验,以更好地了解氨基糖苷类-RNA 的相互作用。体外翻译抑制与抗生素活性之间的线性相关性...

    Directing effect by remote electron-withdrawing protecting groups at O-3 or O-4 position of donors in glucosylations and galactosylations
    摘要:
    Glucosylations and galactosylations of various acceptors with donors possessing an electronwithdrawing benzylsulfonyl, benzoyl, or acetyl group at the O-3 or O-4 position were performed. A beta-directing effect by the benzylsulfonyl group at O-3 of the glucosyl donors and by the benzylsulfonyl and acyl groups at O-4 of the glucosyl donors was observed. In contrast, acyl groups at O-3 of the glucosyl donors and acyl groups at O-3 and O-4 of the galactosyl donors exhibited an alpha-directing effect. The alpha-directing effect is partly considered to remote participation of the acyl groups, whereas the beta-directing effect is somewhat attributed to the S(N)2-like reaction of the acceptor with the glycosyl triflate or the contact ion pair, which is stabilized by remote electron-withdrawing groups. Further evidence for the stability of the alpha-glycosyl triflates was determined by a low-temperature NMR study. (C) 2015 Elsevier Ltd. All rights reserved.

    The first total synthesis of the trisaccharide repeating unit of the O-specific polysaccharide of Pseudomonas fluorescens BIM B-582 is reported. This efficient synthesis involves consecutive 1,2-cis glycosylations including β-l-rhamnosylation and α selective coupling of rare 4-deoxy-d-xylo-hexose as the key steps. The synthetic trisaccharide is equipped with an aminopropyl linker at the reducing end

However, no evidence was found for such a fragmentation of carbonate esters at the 3-O-equatorial, 4-O-axial and -equatorial, and 6-O positions, indicating that neighboring group participation from those sites does not occur under typical glycosylation conditions.
