项目摘要

Carbohydrate recognition in water is a notoriously intractable problem for supramolecular chemists. Saccharides are camouflaged byhydroxyl groups, so are difficult to distinguish from aqueous solvent, the prerequisite for binding. They are also subtly variable, thusdifficult to distinguish from each other. In 2019, the PI's group reported a synthetic receptor for glucose, the most medically relevantmonosaccharide, which exceeded the most optimistic expectations. Their "Glucose-Binding Hexaurea Temple" (GluHUT) boundglucose with high affinity, comparable to most natural receptors, and almost perfect selectivity. The intellectual property for GluHUTwas acquired by Novo Nordisk (NN), the world's leading insulin producer, and now underpins a development programme aimed atglucose-sensitive insulin (GSI), potentially transformative for the treatment of diabetes.Here we propose a programme of work which builds on GluHUT's success. Firstly the glucose-binding properties of the originalGluHUT core will be exploited in new ways. Glucose-sensitive switches will be engineered to open in a controlled fashion, mimickingthe response of the pancreas to glucose concentrations. These switches will then be applied in materials capable of glucose-sensitiveinsulin release. "Phase transfer" applications of lipophilic GluHUTs will also be investigated, especially the potential for glucosetransport across bilayer membranes, and the GluHUT core will be used as the basis for "artificial enzymes" catalysing reactions ofglucose derivatives. Secondly, drawing on lessons from GluHUT, we will pursue the recognition of other carbohydrate targets.Analogues with desymmetrised cores have been identified as candidates for binding saccharides with axial OH, and advancedsoftware enabling a priori design will be developed through collaboration with computational chemists.
对于超分子化学家来说,识别水中的碳水化合物是一个众所周知的棘手问题。糖是被羟基伪装的,因此很难与水溶液区分,这是结合的先决条件。它们也有微妙的变化,因此很难相互区分。2019年,PI小组报告了葡萄糖的合成受体,这是医学上最相关的单糖,超出了最乐观的预期。他们的“葡萄糖结合己糖酸神庙”(GluHUT)以高亲和力结合葡萄糖,可与大多数天然受体相媲美,并且几乎具有完美的选择性。gluhutt的知识产权由全球领先的胰岛素生产商诺和诺德(Novo Nordisk)收购,现在支持一个针对葡萄糖敏感胰岛素(GSI)的开发项目,该项目可能会改变糖尿病的治疗。在此,我们提出了一个以GluHUT的成功为基础的工作计划。首先,将以新的方式利用原有gluhut核心的葡萄糖结合特性。葡萄糖敏感开关将被设计成以可控的方式打开,模仿胰腺对葡萄糖浓度的反应。然后,这些开关将应用于能够释放葡萄糖敏感胰岛素的材料中。亲脂性GluHUT的“相转移”应用也将被研究,特别是葡萄糖跨双层膜运输的潜力,GluHUT核心将被用作“人工酶”催化葡萄糖衍生物反应的基础。其次,借鉴GluHUT的经验,我们将追求其他碳水化合物目标的识别。具有不对称核的类似物已被确定为将糖与轴向OH结合的候选物,并且将通过与计算化学家合作开发能够进行先验设计的先进软件。
