Establishing robust structure-activity relationships (SARs) is key to successful drug discovery campaigns, yet it often remains elusive due to screening and hit validation artifacts (false positives and false negatives), which frequently result in unproductive downstream expenditures of time and resources. To address this issue, we developed an integrative biophysics-driven strategy that expedites hit-to-lead discovery, mitigates false positives/negatives and common hit validation errors, and...
Efficiently driving protein-based fragment screening and lead discovery using two-dimensional NMR
Efficiently driving protein-based fragment screening and lead discovery using two-dimensional NMR
Abstract
Fragment-based drug discovery (FBDD) and validation of small molecule binders using NMR spectroscopy is an established and widely used method in the early stages of drug discovery. Starting from a library of small compounds, ligand- or protein-observed NMR methods are employed to detect binders, typically weak, that become the starting points for structureâ??activity relationships (SAR) by NMR. Unlike the more frequently used ligand-observed 1D...

NMR-based fragment screening and lead discovery accelerated by principal component analysis
Abstract
Protein-based NMR spectroscopy has proven to be a very robust method for finding fragment leads to protein targets. However, one limitation of protein-based NMR is that the data acquisition and analysis can be time consuming. In order to streamline the scoring of protein-based NMR fragment screening data and the determination of ligand affinities using 2D NMR experiments we have developed a data analysis workflow based on principal component...

Abstract
Fragment-based lead discovery (FBLD) has proven fruitful during the past two decades for a variety of targets, even challenging protein-protein interaction (PPI) systems. Nuclear magnetic resonance (NMR) spectroscopy plays a vital role, from initial fragment-based screening to lead generation, because of its power...

Diversity and robustness of NMR based screening methods make these techniques highly attractive as tools for drug discovery. Although not all screening techniques discussed here may be applicable to any given target, there is however a good chance that at least one of the described methods will prove productive in finding several medium affinity ligands. A comparison of each of...

BACKGROUND: Recently, it has been shown that nuclear magnetic resonance (NMR) may be used to identify ligands that bind to low molecular weight protein drug targets. Recognizing the utility of NMR as a very sensitive method for detecting binding, we have...
