  Binding of caffeine by a synthetic co-receptor

  摘要：

  A new co-receptor macrobicyclophane for binding caffeine has been developed. The co-receptor binding sites are based on the hydrogen bonding abilities of secondary amides. H-1 NMR titrations demonstrate recognition of caffeine by formation of a 2:1 complex in CDCl3. (C) 2000 Elsevier Science Ltd. All rights reserved.

  Dual Binding Mode of Methylmethanetriacetic Acid to Tripodal Amidopyridine Receptors

  摘要：

  A series of tripodal amidopyridine receptors capable of selective recognition of methylmethanetriacetic acid (MMTA) in organic solvents is described. Intramolecular hydrogen-bonding groups, built into some of the receptors, were designed as preorganization devices. Binding was studied by NMR titration, variable temperature NMR experiments, 2D-NMR, isothermal titration calorimetry, and single-crystal X-ray crystallography. The results reveal that a balancing act between inter- and intramolecular hydrogen-bonding interactions in the complexes governs both the dynamics and the geometry of binding. Receptor 1b (without intramolecular hydrogen-bonding groups) features a simple symmetric MMTA binding geometry with optimal enthalpic interactions. In sharp contrast, receptor 1a (with intramolecular hydrogen-bonding groups) reveals a temperature-dependent dual binding mode where MMTA can bind in two completely different geometries. The two solution binding geometries of 1a.AMTA were unraveled by NMR experiments and correlated to the X-ray structures.

  thermodynamics of molecular recognition of cis-1,3,5-cyclohexanetricar☐ylic acid by tripodal hosts. Remote intramolecular hydrogen bonds, used to restrict conformationally one of the hosts, exhibit a strong influence on the thermodynamic functions for the binding process ΔH and ΔS, with little effect on ΔG. This suggests that the conformational lock imposed by the intramolecular hydrogen bonds organizes the

  利用可变温度结合研究和等温滴定微量热法，探讨了三脚架宿主对顺式-1,3,5-环己烷三丁酸酯酸的分子识别的热力学。远程分子内氢键（用于构象地限制主体之一）对结合过程ΔH和ΔS的热力学功能表现出很大的影响，而对ΔG的影响很小。这表明由分子内氢键施加的构象锁将受体组织为对于三酸的结合而言不是最佳的构象。
