Ligand binding hotspots are regions of protein surfaces that form particularly favourable interactions with small molecule pharmacophores. Targeting interactions with these hotspots maximises the efficiency of ligand binding. Existing methods are capable of identifying hotspots but often lack assays to quantify ligand binding and direct elaboration at these sites. Herein, we describe a fragment-based competitive 19F Ligand Based-NMR (LB-NMR) screening platform that enables routine, quantitative...

Determination of Ligand-Binding Affinity (Kd) Using Transverse Relaxation Rate (R2) in the Ligand-Observed 1H NMR Experiment and Applications to Fragment-Based Drug Discovery
High hit rates from initial ligand-observed NMR screening can make it challenging to prioritize which hits to follow up, especially in cases where there are no available crystal structures of these hits bound to the target proteins or other strategies to provide affinity ranking. Here, we report a reproducible, accurate, and versatile quantitative ligand-observed NMR assay, which can determine K(d) values of fragments...

Abstract
While Saturation Transfer Difference (STD) is a widely used NMR method for ligand screening, the selection of specific binders requires the validation of the hits through competition experiments or orthogonal biophysical techniques. We show here that the quantitative STD analysis is a reliable and robust approach to...

An NMR strategy for fragment-based ligand screening utilizing a paramagnetic lanthanide probe
An NMR strategy for fragment-based ligand screening utilizing a paramagnetic lanthanide probe
Abstract A nuclear magnetic resonance-based ligand screening strategy utilizing a paramagnetic lanthanide probe is presented. By fixing a paramagnetic lanthanide ion to a target protein, a pseudo-contact shift (PCS) and a paramagnetic relaxation enhancement (PRE) can be observed for both the target protein and its bound ligand. Based on PRE and PCS information, the bound ligand is then screened from the compound library and the structure of the ligandâ??protein complex is determined. PRE is an...
