项目摘要

The Hof research program develops supramolecular binding agents for biological targets in water and other highly competitive solutions. These molecules are unconventional by most views of medicinal and biological chemistry. `Supramolecular binding agents' aren't like drugs or like proteins-they are large, concave, synthetic molecules that describe a binding pocket intended to recognize and bind other molecules. Our program aims to create molecules that will be immediately useful in various applications, and also to uncover fundamental new lessons about how molecules behave in solution. We will create new molecules with new functions that are important in multiple chemical and biological research settings. One set of our applied long-term goals involve creating rapid measurements of biomolecule concentrations and activities (e.g. drug tests, metabolite tests). Nature is salty, and we've learned in recent years how natural salts and other interfering molecules in solution can complicate the creation of successful host molecules. Stimulated by these challenges, we are opening a new track of basic research in which we pursue new fundamental knowledge about the impact of structure, solvent, and solute effects on aqueous molecular recognition. We hope to learn about how natural biomolecular recognition events can tolerate extreme solute concentrations. In the long run, these lessons will feed back into our applied projects, opening avenues for the creation of new salt-tolerant reagents. We are developing new methods on two tracks: molecular diversity and systems chemistry. In the first track, we are introducing new methods to rapidly make and test host molecules for a given property. Some are focused collections of dozens of molecules that explore a novel, biologically compatible (i.e. salt-tolerant) sensing mechanism that we recently invented. Other diversity projects involve new approaches that will allow us to create and test billions of hosts at a time. In the second track, we are inventing ways to create complex adaptive systems made up of dynamic mixtures of host molecules. These have relatively few individual molecules, but they are incredibly complex because they form networks of dynamic connections that change in response to different solution conditions and in response to added analytes. They are designed so the networks can adapt and change themselves in order to achieve a specific task in molecular sensing. In both areas we focus on developing methods that allow rapid synthesis and testing, so that we can quickly identify promising molecules without having to custom-design a host molecule for each and every binding target that might interest us. By taking innovative, method-development approaches, we are creating science that will have a broad impact beyond the individual molecules that we make, and we are also training students who can make their own future impacts in diverse areas of chemical, biology, and biotechnology.
霍夫研究项目开发了用于水和其他高度竞争性解决方案中生物目标的超分子结合剂。这些分子是非常规的医学和生物化学的大多数观点。“超分子结合剂”不像药物或蛋白质,它们是大的、凹形的合成分子,描述了一个旨在识别和结合其他分子的结合口袋。 我们的计划旨在创造在各种应用中立即有用的分子,并揭示有关分子在溶液中如何行为的基本新教训。我们将创造具有新功能的新分子,这些新功能在多种化学和生物研究环境中非常重要。我们应用的一组长期目标涉及创建生物分子浓度和活性的快速测量(例如药物测试,代谢物测试)。自然界是咸的,近年来我们已经了解到溶液中的天然盐和其他干扰分子是如何使成功的宿主分子的创造复杂化的。在这些挑战的刺激下,我们正在开辟一条新的基础研究道路,在这条道路上,我们追求关于结构,溶剂和溶质效应对水分子识别的影响的新的基础知识。我们希望了解自然的生物分子识别事件如何能够容忍极端的溶质浓度。从长远来看,这些经验教训将反馈到我们的应用项目中,为创造新的耐盐试剂开辟道路。我们正在两个方面开发新方法:分子多样性和系统化学。在第一个轨道中,我们正在引入新的方法来快速制造和测试给定属性的宿主分子。有些是几十种分子的集中集合,这些分子探索了我们最近发明的一种新颖的、生物相容的(即耐盐的)传感机制。其他多样性项目涉及新的方法,使我们能够一次创建和测试数十亿台主机。在第二个轨道中,我们正在发明创造由宿主分子的动态混合物组成的复杂自适应系统的方法。它们具有相对较少的单个分子,但它们非常复杂,因为它们形成动态连接的网络,这些网络会响应不同的溶液条件和添加的分析物而变化。它们的设计使网络能够适应和改变自己,以实现分子传感中的特定任务。在这两个领域,我们专注于开发允许快速合成和测试的方法,以便我们可以快速识别有希望的分子,而不必为我们可能感兴趣的每个结合靶点定制设计宿主分子。通过采取创新的方法开发方法,我们正在创造的科学将产生广泛的影响,超越我们所做的单个分子,我们也在培养学生谁可以在化学,生物学和生物技术的不同领域作出自己的未来的影响。
