    Synthesis and Metal Ion Binding Studies of Enediyne-Containing Crown Ethers
    摘要:
    The 3-ene-1,5-diyne crown ether 5 is a novel enediyne-containing crown ether that was designed as a model system for a class of enediynes that might undergo alkali metal ion-triggered Bergman cyclization. We report the preparation of 5 by two different routes. In the shorter and preferable route, a carbenoid coupling reaction is employed to simultaneously construct the enediyne moiety and effect a macrocyclization of an acyclic bis(propargyl)bromide 15 to the 24-membered crown ether 5. Under standard reaction conditions, this carbenoid coupling produces as the major product the isomeric 5-ene-1,3-diyne-crown ethers (Z)-16 and (E)-16. The formation of 5-ene-1,3-diynes from the carbenoid coupling of propargyl bromides is unprecedented. We present evidence that it is the polyether nature of dibromide 15 that leads to the formation of the 5-ene-1,3-diyne-crown ether products. Judicious control of the reaction conditions can be used to produce either 5 or (Z)-16 from 15 in synthetically useful yields. Both enediyne-crown ethers 5 and (Z)-16 bind alkali metal ions, as evidenced by their ability to extract alkali metal picrates into organic solvents. Enediyne-crown ether 5 undergoes Bergman cyclization at 135 degrees C in DMSO/1,4-cyclohexadiene to produce the known o-xylyl crown ether 4. Crown ether 5 represents an enediyne in which molecular recognition of alkali metals might serve as a trigger for Bergman cyclization.

    三唑基取代的 β-环糊精二聚体中反转现象的限制
    摘要:
    通过铜催化的叠氮炔环加成反应合成了六种不同的β-环糊精(β-CD)二聚体。连接两个 β-CD 的间隔物的性质在长度和亲水性上有所不同。对于每个二聚体,在 D2O 中进行了详细的 NMR 研究。发现具有短间隔区的 β-CD 二聚体仅表现出一种构象,而具有长和/或疏水性间隔区的 β-CD 二聚体则表现出两种不同的构象。事实上,后者经历了一个倒置过程,导致垫片自包含在两个 CD 腔之一中。六个 β-CD 二聚体在水中的行为因此被合理化,这允许确定实际可用于分子识别的“自由”空腔的比例。

  • Multivalent iminosugars to modulate affinity and selectivity for glycosidases
    作者:Jennifer Diot、M. Isabel García-Moreno、Sébastien G. Gouin、Carmen Ortiz Mellet、Karsten Haupt、José Kovensky
    DOI:10.1039/b815408b
    日期:——
    A series of mono-, di- and tri-valent iminosugars based on oligoethylene scaffolds and N-substituted deoxynojirymicin epitopes have been synthesized by “click chemistry” to study the effect of multivalency on glycosidase inhibition. Biological evaluation evidenced differences in the inhibition trends as a function of the enzyme nature. The results demonstrate that multivalency can be used in some case to modulate both the affinity and the selectivity of glycosidase inhibition.

    antiviral therapies that have been specifically approved to treat ZIKV, and there is an urgent need to develop effective anti-ZIKV agents. Here, we report anti-ZIKV activity of 16 synthetic carbohydrate receptors (SCRs) that inhibit ZIKV infection in Vero and HeLa cells. Using a ZIKV reporter virus particle-based infection assay, our data demonstrates these SCRs are highly potent with IC50s as low as
