reactions in intact cells, cell lysates or membrane preparations represents a major advance in the lead discovery process. Despite the relevance of assaying in physiological conditions, only a small number of biophysical techniques, often requiring complex set‐up, are applicable to these sample types. Here, we demonstrate the first application of n‐fluorine atoms for biochemical screening (n‐FABS), a homogeneous
测量完整细胞,细胞裂解液或膜制剂中特定酶促反应抑制剂的作用的可能性代表了潜在发现过程中的一项重大进展。尽管在生理条件下进行测定具有相关性,但只有少数生物物理技术(通常需要复杂的设置)适用于这些样品类型。在这里,我们展示了n-氟原子在生化筛选(n- FABS)中的首次应用,这是一种基于19 F NMR光谱的均一且通用的测定方法,用于检测细胞膜酶的高亲和力和低亲和力抑制剂提取物及其IC 50的测定价值观。我们的方法可以发现针对难以纯化或需要进行膜缔合的靶标的新型结合片段。这些结果为该方法在这些相关和复杂的生物系统中的未来应用铺平了道路。
Development of Fragment-Based<i>n</i>-FABS NMR Screening Applied to the Membrane Enzyme FAAH
Fluorine for fragments: We demonstrate the first application of 19F NMR fragment‐based biochemical screening (n‐FABS) to the membrane protein fatty acid amide hydrolase (FAAH). Fragment hits were identified through this method that exhibit micromolar inhibitory values against FAAH, showing the potential for this method with other membrane protein applications.
