  用两亲性Janus Glycodendrimers自组装的可编程聚糖配体模拟生物膜

  摘要：

  加速的模块合成产生了18种两亲性Janus糖树状聚合物，具有由两个或一个碳水化合物头基或具有非碳水化合物亲水性臂的混合构象形成的三种不同拓扑。通过将它们的THF溶液简单地注入到水或缓冲液中，所有Janus化合物就会自组装成均匀，稳定和柔软的单层囊泡，称为糖树状大分子。混合的星座拓扑糖树状大分子被证明在结合植物，细菌和人凝集素方面最有效。具有生物医学相关受体的证据为这种糖类树状小体在靶向药物递送，疫苗和纳米医学的其他领域中的应用提供了有希望的前景。

  A fourth wheel: Two sets of bifunctional AB2C dendrimers having internal acetylene/azides and external hydroxy groups were constructed utilizing benign synthetic protocols. An in situ postfunctionalization strategy was successfully carried out to illustrate the chemoselective nature of these dendrimers. The dendrimers were also transformed into dendritic nanoparticles or utilized as dendritic crosslinkers

  A library of eight amphiphilic Janus glycodendrimers (Janus-GDs) presenting D-lactose (Lac) and a combination of Lac with up to eight methoxytriethoxy (3EO) units in a sequence-defined arrangement was synthesized via an iterative modular methodology. The length of the linker between Lac and the hydrophobic part of the Janus-GDs was also varied. Self-assembly by injection from THF solution into phosphate-buffered saline led to unilamellar, monodisperse glycodendrimersomes (GDSs) with dimensions predicted by Janus-GD concentration. These GDSs provided a toolbox to measure bioactivity profiles in agglutination assays with sugar-binding proteins (lectins). Three naturally occurring forms of the human adhesion/growth-regulatory lectin galectin-8, Gal-8S and Gal-8L, which differ by the length of linker connecting their two active domains, and a single amino acid mutant (F19Y), were used as probes to study activity and sensor capacity. Unpredictably, the sequence of Lac on the Janus-GDs was demonstrated to determine bioactivity, with the highest level revealed for a Janus-GD with six 3EO groups and one Lac. A further increase in Lac density was invariably accompanied by a substantial decrease in agglutination, whereas a decrease in Lac density resulted in similar or lower bioactivity and sensor capacity. Both changes in topology of Lac presentation of the GDSs and seemingly subtle alterations in protein structure resulted in different levels of bioactivity, demonstrating the presence of regulation on both GDS surface and lectin. These results illustrate the applicability of Janus-GDs to dissect structure activity relationships between programmable cell surface models and human lectins in a highly sensitive and physiologically relevant manner.

  A dendritic structure includes a core and repeating units, wherein the repeating units comprise units of the type AB x C y , wherein x is 2, 3, or 4, wherein y is 1, 2, or 3, wherein C is selected from the group consisting of azides and alkynes, and wherein every repeating unit is bound to at least one other unit with at least one bond selected from the group consisting of the group consisting of an ester, an amide, a thioether, an ether, a urethane, an amine, and an imine. Advantages include that a “one-pot” growth of the dendritic structure is possible. It is possible to have more functional groups in a dendritic structure. It is possible to add different functional groups simultaneously both to an inner layer and to an outer layer in a dendritic structure.
