  • Heterobifunctional Multivalent Inhibitor-Adaptor Mediates Specific Aggregation between Shiga Toxin and a Pentraxin
    作者:Dmitry Solomon、Pavel I. Kitov、Eugenia Paszkiewicz、Gordon A. Grant、Joanna M. Sadowska、David R. Bundle
    DOI:10.1021/ol051529+
    日期:2005.9.1
    This multivalent inhibitor-adaptor is able to capture a "target" receptor (Shiga toxin) through its recognition of one ligand of a heterobivalent headgroup while the other ligand binds to an endogenous "trap" protein (serum amyloid P component, SAP). BAIT showed markedly enhanced inhibition of toxin activity. An efficient synthesis of this multivalent cluster containing heterobifunctional ligands
    [反应:见正文]描述了称为“ BAIT”的多价异功能抑制剂-适配器的第一个例子。这种多价抑制剂-适应剂能够通过识别异二价头基的一个配体而捕获“靶”受体(志贺毒素),而另一种配体与内源性“捕获”蛋白(血清淀粉样蛋白P组分,SAP)结合。BAIT显示出对毒素活性的抑制作用显着增强。通过化学和化学酶学方法可以有效合成含有异双功能配体的多价簇。
  • Carbohydrate-centered maleimide cluster as a new type of templates for multivalent peptide assembling

    application as a new type of templates for multivalent peptide assembling. Simultaneous introduction of multiple maleimide functionalities onto a carbohydrate core was achieved through the reaction of carbohydrate-based polyamines with methoxycarbonylmaleimide or with the N-hydroxylsuccinimide ester of 6-maleimidohexanoic acid. The clustered maleimides placed on the carbohydrate core allow rapid and highly
    本文描述了以碳水化合物为中心的马来酰亚胺簇的简便合成方法及其作为多价肽组装的新型模板的应用。通过将基于碳水化合物的聚胺与甲氧基羰基马来酰亚胺或与6-马来酰亚胺基己酸的N-羟基琥珀酰亚胺酯反应,将多种马来酰亚胺官能团同时引入到碳水化合物核中。置于碳水化合物核心上的成簇的马来酰亚胺允许在室温下,在几乎中性的条件下,与多拷贝的含半胱氨酸的肽快速且高度化学选择性地连接。这种温和高效的连接方法对于合成大而复杂的多价肽非常有价值,而这些肽通常无法通过常规连接方法获得。马来酰亚胺簇作为用于多价肽合成的新型模板的有用性通过合成结合有效HIV抑制剂T20的序列的两个四价gp41肽来举例说明。合成的多价gp41肽可用作新型免疫原,以产生用于HIV研究的特异性抗体。它们也是研究HIV膜融合机制的有用探针。

Immobilized carbohydrate units can thus be used to directly detect these agents or as a platform for inhibitor assessment. In this work, modified glycosides were patterned on gold surfaces to monitor the binding of the homopentameric

  • On the Nature of the Multivalency Effect:  A Thermodynamic Model
    作者:Pavel I. Kitov、David R. Bundle
    DOI:10.1021/ja038223n
    日期:2003.12.1
    A quantitative model is proposed for the analysis of the thermodynamic parameters of multivalent interactions in dilute solutions or with immobilized multimeric receptor. The model takes into account all bound species and describes multivalent binding via two microscopic binding energies corresponding to inter- and intramolecular interactions (DeltaGdegrees(inter) and DeltaGdegrees(intra)), the relative contributions of which depend on the distribution of complexes with different numbers of occupied binding sites. The third component of the overall free energy, which we call the "avidity entropy" term, is a function of the degeneracy of bound states, Omega(i), which is calculated on the basis of the topology of interaction and the distribution of all bound species. This term grows rapidly with the number of receptor sites and ligand multivalency, it always favors binding, and explains why multivalency can overcome the loss of conformational entropy when ligands displayed at the ends of long tethers are bound. The microscopic parameters DeltaGdegrees(inter) and DeltadegreesG(intra) may be determined from the observed binding energies for a set of oligovalent ligands by nonlinear fitting with the theoretical model. Here binding data obtained from two series of oligovalent carbohydrate inhibitors for Shiga-like toxins were used to verify the theory. The decavalent and octavalent inhibitors exhibit subnanomolar activity and are the most active soluble inhibitors yet seen that block Shiga-like toxin binding to its native receptor. The theory developed here in conjunction with our protocol for the optimization of tether length provides a predictive approach to design and maximize the avidity of multivalent ligands.
