    Docking, synthesis, and NMR studies of mannosyl trisaccharide ligands for DC-SIGN lectin
    摘要:
    DC-SIGN是一种存在于未成熟树突状细胞表面的凝集素,如今成为设计新型抗病毒药物的有前景的目标。这种凝集素识别存在于多种病原体表面的高度糖基化蛋白,如HIV、埃博拉病毒、白色念珠菌、结核分枝杆菌等。了解这种凝集素的结合模式是一个极为有趣的话题,将允许合理设计新型且更具选择性的配体。在此,我们介绍了用于研究二糖和三糖与DC-SIGN相互作用的计算和实验工具。已经进行了涉及甘露糖基二糖和三糖以及DC-SIGN的碳水化合物识别域(CRD)的复合物的对接分析。三糖Manα1,2[Manα1,6]Man 1和Manα1,3[Manα1,6]Man 2是从一个正交保护的甘露糖作为共同中间体合成的。使用这些配体和可溶性胞外域(ECD)的DC-SIGN,基于STD和transfer-NOE的NMR实验提供了额外的信息。进行了甘露糖基配体在自由和结合状态下的构象分析。这些研究表明,三糖中位置2或3的末端甘露糖是最重要的部分,并且与凝集素的结合位点呈现最强的接触。可以提出多种结合模式,因此在设计新配体时应予以考虑。

  • A bivalent glycopeptide to target two putative carbohydrate binding sites on FimH
    作者:Thisbe K Lindhorst、Kathrin Bruegge、Andreas Fuchs、Oliver Sperling
    DOI:10.3762/bjoc.6.90
    日期:——

    FimH is a mannose-specific bacterial lectin found on type 1 fimbriae with a monovalent carbohydrate recognition domain (CRD) that is known from X-ray studies. However, binding studies with multivalent ligands have suggested an additional carbohydrate-binding site on this protein. In order to prove this hypothesis, a bivalent glycopeptide ligand with the capacity to bridge two putative carbohydrate binding sites on FimH was designed and synthesized. Anti-adhesion assays with the new bivalent ligand and type 1-fimbriated bacteria have revealed, that verification of the number of carbohydrate binding sites on FimH with a tailor-made bivalent glycopeptide requires further investigation to be conclusive.

    FimH是一种在第1型纤毛上发现的甘露糖特异性细菌凝集素,具有已知的单价碳水化合物识别结构域(CRD),这是通过X射线研究得知的。然而,使用多价配体进行结合研究表明该蛋白上存在额外的碳水化合物结合位点。为了证明这一假设,设计并合成了一种具有桥接FimH上两个假定碳水化合物结合位点能力的双价糖肽配体。使用新的双价配体和第1型纤毛细菌进行抗粘附实验表明,使用定制的双价糖肽验证FimH上碳水化合物结合位点数量需要进一步的研究才能得出结论。

    The present disclosure provides conjugates that comprise an insulin molecule conjugated via a conjugate framework to two or more separate ligands that each include a saccharide, wherein the framework, ligand, saccharide and insulin molecule optionally comprise a fatty chain (e.g., a C8-30 fatty chain), wherein when said insulin molecule is conjugated both to a C8-30 fatty chain and one or more separate ligands that each include a saccharide, said C8-30 fatty chain is linked to insulin molecule only, and wherein when the framework or ligand comprises a fatty chain the insulin molecule is conjugated to two or more separate ligands. In certain embodiments, a conjugate is characterized in that, when the conjugate is administered to a mammal, at least one pharmacokinetic (PK) and/or pharmacodynamic (PD) property of the conjugate is sensitive to serum concentration of a second saccharide. In certain embodiments, a conjugate is also characterized by having a protracted PK profile. Exemplary conjugates and sustained release formulations are provided in addition to methods of use and preparation.
