    通过识别编码的三聚氰胺低聚物形成高保真序列选择性双链体
    摘要:
    三聚氰胺低聚物由重复的三嗪-哌啶单元组成,并配有苯酚和氧化膦侧链,形成 H 键合的双链体。三聚氰胺骨架提供了足够的刚性,以防止寡聚体分子内折叠长达三个识别单元,从而在序列互补寡聚体之间形成可靠的双链体。核磁共振光谱和等温滴定量热法 (ITC) 用于表征低聚物的自组装特性。对于长度互补的均聚物,在甲苯中形成双链体的特征是添加到链中的每个碱基对的稳定性增加一个数量级。AD稀溶液的核磁共振谱2-mer 表明链上相邻识别单元之间的分子内 H 键(1,2 折叠)不会发生。AAD和ADD 3-mer的稀释溶液的 NMR 谱表明,1,3-折叠也没有发生。ITC 用于表征六个不同 3 聚体序列的所有成对组合之间的相互作用,并且序列互补双链体比具有单个碱基错配的双链体稳定大约一个数量级。高保真双链体形成与单体构建块的合成可访问性相结合,使这些系统成为进一步研究的有吸引力的目标。

    The formation of well-defined supramolecular assemblies involves competition between intermolecular and intramolecular interactions, which is quantified by effective molarity. Formation of a duplex between two oligomers equipped with recognition sites displayed along a non-interacting backbone requires that once one intermolecular interaction has been formed, all subsequent interactions take place
    明确定义的超分子组装体的形成涉及分子间相互作用和分子内相互作用之间的竞争,这通过有效摩尔浓度来定量。在配备有沿非相互作用主链显示的识别位点的两个低聚物之间形成双链体要求,一旦形成一个分子间相互作用,所有后续相互作用均在分子内进行。此过程的效率由连接识别位点的主链的几何互补性和构象灵活性决定。在这里,我们报告了一系列的氧化膦氢键受体AA 2聚体和苯酚氢键供体DD 2聚体,其中两个识别位点通过几何形状和柔韧性不同的异构主链模块连接。所有AA和DD组合均形成稳定的AA·DD双链体,与仅能形成一个氢键的相应A·D配合物相比,两个协同氢键的稳定性提高了一个数量级。对于所有六个可能的骨架组合,双链体形成的有效摩尔浓度近似恒定(7–20 mM)。因此,有效的超分子组装不需要严格的互补性和高度的预组织。只要有一定的灵活性,就可以互换使用完全不同的主干模块来构建稳定的H键双工。因此,有效的超分子组装不需要严

  • Relationship between Chemical Structure and Supramolecular Effective Molarity for Formation of Intramolecular H-Bonds
    作者:Hongmei Sun、Christopher A. Hunter、Cristina Navarro、Simon Turega
    DOI:10.1021/ja406235d
    日期:2013.9.4
    Effective molarity (EM) is a key parameter that determines the efficiency of a range of supramolecular phenomena from the folding of macromolecules to multivalent ligand binding. Coordination complexes formed between zinc porphyrins equipped H-bond donor sites and pyridine ligands equipped with H-bond acceptor sites have allowed systematic quantification of EM values for the formation of intramolecular H-bonds in 240 different systems. The results provide insights into the relationship of EM to supramolecular architecture, H-bond strength, and solvent. Previous studies on ligands equipped with phosphonate diester and ether H-bond acceptors were inconclusive, but the experiments described here on ligands equipped with phosphine oxide, amide, and ester H-bond acceptors resolve these ambiguities. Chemical double-mutant cycles were used to dissect the thermodynamic contributions of individual H-bond interactions to the overall stabilities of the complexes and hence determine the values of EM, which fall in the range 1-1000 mM. Solvent has little effect on EM, and the values measured in toluene and 1,1,2,2-tetrachloroethane are similar. For H-bond acceptors that have similar geometries but different H-bond strengths (amide and ester), the values of EM are very similar. For H-bond acceptors that have different geometries but similar H-bond strengths (amide and phosphonate diester), there is, little correlation between the values of EM. These results imply that supramolecular EMs are independent of solvent and intrinsic H-bond strength but depend on supramolecular architecture and geometric complementarity.
