The application is integrated into the project Covid19-NMR that started March 26th, 2020. In this international with more than 30 Partners from 10 countries, all viral RNAs and viral proteins of SARS-CoV-2 are produced and their NMR spectra analyzed and assignment. The biochemical production and the NMR-spectroscopic characterization (NMR assignments) forms the basis for a large screening project. The infrastructural support for this screening project is the topic of the current application. The aim of Covid19-NMR is to screen up to 20 viral proteins and 40 viral RNAs for binding of ligands and drugs. The low molecular weight compounds are assembled in five different libraries with up to 1000 ligands. Ligand-based screening is divided into ligands with 19F atoms and ligands without 19F. 19-based screening offers a number of advantages over 1H-based screening. Therefore, we apply for the upgrade of an existing 600 MHz-NMR-spectrometer with a 19F cryogenic probe allowing for 1H decoupling. To do so, we need to renew a 20 year old console and the associated cryogenic cooling unit. Evaluation of this applciation is urgent. The producing company Bruker, the sole company providing such eqiupment, has offered to deliver the equipment till August 2020 in order to expedite research in Covid19-NMR.

该应用程序已集成到2020年3月26日开始的Covid 19-NMR项目中。在这个由来自10个国家的30多个合作伙伴组成的国际组织中，生产了SARS-CoV-2的所有病毒RNA和病毒蛋白，并对其NMR谱进行了分析和归属。生化生产和NMR光谱表征（NMR分配）形成了大型筛选项目的基础。该筛选项目的基础设施支持是当前应用程序的主题。Covid 19-NMR的目的是筛选多达20种病毒蛋白和40种病毒RNA，以确定配体和药物的结合。低分子量化合物组装在五个不同的库中，具有多达1000个配体。基于配体的筛选分为具有19 F原子的配体和不具有19 F原子的配体。19-基于1H的筛选提供了许多优于基于1H的筛选的优点。因此，我们申请升级现有的600 MHz NMR光谱仪，配备19 F低温探头，允许1H去耦。要做到这一点，我们需要更新一个20岁的控制台和相关的低温冷却单元。对这一应用的评价是迫切的。生产公司布鲁克是唯一提供此类设备的公司，已提出将设备交付至2020年8月，以加快Covid 19-NMR的研究。
