  • Stereoselective synthesis of light-activatable perfluorophenylazide-conjugated carbohydrates for glycoarray fabrication and evaluation of structural effects on protein binding by SPR imaging

    A series of light-activatable perfluorophenylazide (PFPA)-conjugated carbohydrate structures have been synthesized and applied to glycoarray fabrication. The glycoconjugates were structurally varied with respect to anomeric attachment, S-, and O-linked carbohydrates, respectively, as well as linker structure and length. Efficient stereoselective synthetic routes were developed, leading to the formation of the PFPA-conjugated structures in good yields over few steps. The use of glycosyl thiols as donors proved especially efficient and provided the final compounds in up to 70% total yield with high anomeric purities. PFPA-based photochemistry was subsequently used to generate carbohydrate arrays on a polymeric surface, and surface plasmon resonance imaging (SPRi) was applied for evaluation of carbohydrate-protein interactions using the plant lectin Concanavalin A (Con A) as a probe. The results indicate better performance and equal efficiency of S- and O-linked structures with intermediate linker length.

  • Assessing the cluster glycoside effect during the binding of concanavalin A to mannosylated artificial lipid rafts

    weak intramembrane chelation of Con A. Despite this observation, concentrating the mannosyl lipids into artificial lipid rafts did not significantly improve affinity for Con A. This lack of a cluster glycoside effect was ascribed to lipid congestion inhibiting intra-raft chelation of Con A, and implies that glycolipids located in lipid rafts may not necessarily be preorganised for multivalent binding.
    具有全氟烷基膜锚的甘露糖糖脂已经合成。当插入囊泡中时,这些甘露糖基脂质要么均匀地分散在表面上,要么存在胆固醇相分离成人造脂质筏。在1%mol / mol时,分散的甘露糖基脂质对Con A的亲和力比溶液中弱3倍,这可能反映了表面的空间封闭。但是,将膜负荷增加5倍,会使Con A的亲和力增加多达75%,并表明Con A的膜内螯合作用较弱。尽管有此观察结果,将甘露糖基脂质浓缩到人造脂质筏中并不能显着改善对Con A的亲和力。簇糖苷效应归因于脂质充血抑制了Con A的筏内螯合,并暗示位于脂质筏中的糖脂可能不一定是预先组织的以进行多价结合。

    Thirty novel 20 (S)-O-linked camptothecin (CPT) glycoconjugates were synthesized. They showed more potent in vitro cytotoxicities over irinotecan, but very weak direct topoisomerase I (Topo I) inhibition was observed at 100.0 μM. Oligosaccharide types, length of a PEG linker and acetyl groups exerted obvious effects on cytotoxicity, selectivity, water solubility and stability of the newly synthesized

    high‐affinity lectin ligands is critical for enhancing the inherently weak binding affinities of monomeric carbohydrates to their binding proteins. Glycogold nanoparticles (glyco‐AuNPs) are promising multivalent glycan displays that can confer significantly improved functional affinity of glyco‐AuNPs to proteins. Here, AuNPs are functionalized with several different carbohydrates to profile lectin affinities
    高亲和力凝集素配体的设计对于增强单体碳水化合物与其结合蛋白固有的弱结合亲和力至关重要。糖纳米颗粒(glyco-AuNPs)是有前途的多价聚糖展示,可以显着提高糖AuNPs对蛋白质的功能亲和力。在这里,AuNP被几种不同的碳水化合物官能化,以分析凝集素的亲和力。我们证明了用包含聚糖(70 mol%)和两亲性接头(30 mol%)的混合醇化配体功能化的AuNPs在含有高浓度盐和蛋白质的溶液中提供了长期稳定性,没有非特异性蛋白质吸附的证据。这些高度稳定的糖基AuNP可检测模型植物凝集素,例如伴刀豆球蛋白A,小麦胚芽凝集素和通过紫外/可见分光光度法和动态光散射分别在亚纳摩尔和低皮摩尔平下的蓖麻蓖麻凝集素120。此外,我们在定向的固定抗体微阵列上开发了基于原糖基于AuNPs的凝集反应,从而可以用肉眼高度敏感地检测凝集素。另外,该微阵列能够检测在其他环境条件下或在样品混合物中单独存在的凝集素。这
