Fluorine atoms are absent in most common solvents, buffer components and biomolecules, resulting in simpler datasets to analyze when compared to proton-based methods. In this context, the usage of fluorinated compounds as spy molecules presents yet further advantages. 3 If the binding affinity of the spy molecule is known, the affinity of the competitors can be estimated from the extent of the displacement. bound state of the spy molecule can be detected by monitoring different NMR parameters and is dependent on the affinity of the competitor. ![]() The increased relative population of free vs. When a competing ligand is present, the spy molecule will be displaced from its binding site. ![]() 2 Competitive ligands are detected by monitoring the signals of a known binder, also referred to as a reporter or spy molecule. 1Ī powerful approach to detect binders across a range of affinities consists in competition ligand-observed NMR experiments. ![]() Both the large number of methods available and the ability to detect weak interactions imperceptible to other biophysical techniques make NMR a valuable resource for pharmaceutical research, from fragment-based drug discovery (FBDD) to lead optimization campaigns. Over the past few years, the application of nuclear magnetic resonance (NMR) to study small molecule interactions with biomolecular targets has increased.
