    用于调节 TLR4 依赖性炎症的新型硫酸二糖的合成
    摘要:
    天然硫酸化聚糖是通过 TLR4 激活引起炎症的关键因素;因此,合成的外源硫酸糖可用于下调炎症过程。我们基于能够穿过血脑屏障的小型且具有生物相容性的碳水化合物,设计并合成了新的硫酸化化合物。从独特的前体获得的合适的受保护的供体和受体已被立体选择性糖基化,得到正交保护的纤维二糖二糖。选择性脱保护和硫酸化可以合成四种不同硫酸化的二糖,并通过 NMR、HRMS 和 MS/MS 对其进行了表征。新化合物与其部分受保护的前体一起在 HEK-TLR4 细胞上进行了测试。我们的结果显示了小寡糖调节 TLR4 活性的潜力,证实了硫酸化的必要性以及 6-硫酸基团在触发 TLR4 信号传导方面的关键作用。

  • 2,4,6-Trichloro-1,3,5-triazine (TCT) mediated one-pot sequential functionalisation of glycosides for the generation of orthogonally protected monosaccharide building blocks
    作者:Madhubabu Tatina、Syed Khalid Yousuf、Debaraj Mukherjee
    DOI:10.1039/c2ob25452b
    日期:——
    Orthogonally protected monosaccharide building blocks have been prepared using TCT in a one-pot multicomponent transformation. The process involves successive steps of arylidene acetalation, esterification and regioselective reductive acetal cleavage. High regioselectivity, scope for using a broad range of substrates, functional group tolerance, mild reaction conditions, easy handling process and wide application range are a few advantages of the current process.

    development of general and expedient methodologies for the preparation of orthogonally protected glycoside building blocks is essential for the efficient synthesis of complex oligosaccharides. Herein, we describe a new approach that uses copper(II) triflate as a versatile catalyst for the one-pot preparation of orthogonal protected thio- and O-glycosides from the corresponding unprotected counterparts.

  • “Super Armed” Glycosyl Donors:  Conformational Arming of Thioglycosides by Silylation
    作者:Christian Marcus Pedersen、Lars Ulrik Nordstrøm、Mikael Bols
    DOI:10.1021/ja071955l
    日期:2007.7.1
    Glycosyl donors protected with bulky silyl protective groups (tert-butyldimethylsilyl, TBS), on the 2-, 3-, and 4-OH groups were found to have superior reactivity compared with benzylated thioglucosides. The enhanced reactivity is explained by the stereoelectronic effects associated with the conformational change induced by the silylation. A TBS silylated thioglucoside donor has axial OR groups, whereas a benzylated thioglucoside has equatorial OR groups, leading to much more favorable charge-dipole interactions in the transition state. This concept could be used to create "super armed" glucosyl, mannosyl, rhamnosyl, and galactosyl donors, which could cross-couple with the armed acceptors, phenyl 2,3,4-tri-O- benzyl-beta-D-thioglucoside or phenyl 2,3,6-tri-O-benzyl-beta-D-thioglucoside, to give the corresponding armed disaccharides in good to excellent yields.
