Upgrade of a 500 MHz NMR Spectrometer for Applications in Biomedical Research

描述（由申请人提供）：对于那些制造和/或结构表征生物医学相关有机、有机金属和聚合物的人来说，核磁共振（NMR）光谱是最有价值的光谱工具。获得高质量的核磁共振数据对这些领域的研究进展至关重要。要求升级到我们目前的500 MHz NMR光谱仪的现代能力将大大提高明尼苏达州目前正在研究的无数生物医学项目的进展。具体而言，将受益于这一工具的项目类型包括抗肿瘤剂的合成， 抗生素，疫苗和其他生物活性化合物;创建用于监测临床相关电解质水平的新传感器;探索重要的酶途径和功能;金属酶模型的生物无机研究;开发适用于（不对称）合成药剂;测定新的生物活性天然和非天然产物的结构;新的造影剂的设计用于成像;新的聚合物为基础的车辆和药物和基因传递策略的发展;聚合物人工组织的研究;和碳水化合物为基础的树枝状聚合物和聚合物的探索用作新的'治疗诊断'剂。 更具体地说，我们要求资金升级我们现有的500 MHz NMR光谱仪，配备新的控制台、最先进的探头和自动进样器。该光谱仪将被安置在化学系的NMR实验室，在那里它将被用来对明尼苏达大学正在合成和研究的用于生物医学研究目的的小分子和大分子进行一维和二维多核实验。该设施可满足近300名研究人员的需求，其中约一半是该应用程序中主要和次要用户的研究小组。我们希望我们庞大的用户群能够从所要求的升级所提供的多功能性中受益匪浅。由于新探头具有自动调谐和匹配功能以及自动进样器的综合功能，我们将能够在最少操作员干预的情况下为任何样品类型的任何实验序列生成高质量的光谱数据（小分子或大分子;有机或无机; 1H、13 C、19 F、31 P、2 H、15 N、17 O、11 B、51 V、119 Sn、59 Co或29 Si）。这是非常强大的。这些能力远远超过了我们目前的仪器所能做到的。通过这次升级，我们将获得更高质量的数据和更多的数据。其直接结果是，发现的速度和理解的深度都将得到推进。

DESCRIPTION (provided by applicant): Nuclear magnetic resonance (NMR) spectroscopy is the most valuable spectroscopic tool for those who make and/or structurally characterize biomedically relevant organic, organometallic, and polymeric compounds. Access to high quality NMR data is critical to research progress in each of these fields. The modern capabilities of the requested upgrade to our current 500 MHz NMR spectrometer will greatly enhance progress in a myriad of biomedically-motivated projects currently under study at Minnesota. Specifically, the types of projects that will benefit from this instrument include the synthesis of antitumor agents, antibiotics, vaccines, and other bioactive compounds; creation of new sensors for monitoring levels of clinically relevant electrolytes; exploration of important enzyme pathways and functions; bioinorganic studies of models of metalloenzymes; development of new organometallic-based methods applicable to the (asymmetric) synthesis of pharmaceutical agents; determination of structures of new biologically active natural and unnatural products; design of new contrast agents for imaging; the development of new polymer-based vehicles and strategies for both drug and gene delivery; studies of polymeric artificial tissues; and exploratio of carbohydrate-based dendrimers and polymers for use as novel 'theranostic' agents. More specifically, we request funds to upgrade our existing 500 MHz NMR spectrometer with a new console, state-of-the-art probe and automatic sample changer. This spectrometer will be housed in the NMR Laboratory in the Department of Chemistry, where it will be used to perform one- and two-dimensional multinuclear experiments on small and large molecules being synthesized and studied for biomedical research purposes here at the University of Minnesota. This facility serves the needs of nearly 300 researchers, approximately half of whom are in the research groups of the Major and Minor Users in this application. We expect our large user base to benefit tremendously from the versatility afforded by the requested upgrade. Given the combined features of the new probe, which includes automatic tuning and matching capabilities, and autosampler, we will be able to generate, with minimal operator intervention, high quality spectral data for any sequence of experiment(s) with any sample type (small molecules or macromolecules; organic or inorganic; 1H, 13C, 19F, 31P, 2H, 15N, 17O, 11B, 51V, 119Sn, 59Co, or 29Si). This is very powerful. These capabilities far exceed what we can do with our current instrument. With this upgrade we will obtain higher quality data and more data. As a direct consequence, both the pace of discovery and depth of understanding will be advanced.
