NMR-based platform for fragment-based lead discovery used in screening BRD4-targeted compounds

Fragment-Based Lead Discovery by NMR

fragment-based lead discovery because it combines high sensitivity and robustness to loose fragment binders with unique structural resolution and throughput. Favourable applications include screening against shallow binding pockets (such as protein-protein interactions) and side-pockets outside the highly conserved active centre of the major target classes (such as protein kinases and proteases...

Fragment - based Lead Discovery

Process of Fragment-Based Lead Discovery-A Perspective from NMR.

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 to probe the intrinsically weak interactions between targets and low-molecular-we...

Integrated biophysical approach to fragment screening and validation for fragment-based lead discovery.

In fragment-based drug discovery, the weak affinities exhibited by fragments pose significant challenges for screening. Biophysical techniques are used to address this challenge, but there is no clear consensus on which cascade of methods is best suited to identify fragment hits that ultimately translate into bound X-ray structures and provide bona fide starting points for synthesis. We have be...

A False-Positive Screening Hit in Fragment-Based Lead Discovery: Watch out for the Red Herring.

With the rising popularity of fragment-based approaches in drug development, more and more attention has to be devoted to the detection of false-positive screening results. In particular, the small size and low affinity of fragments drives screening techniques to their limit. The pursuit of a false-positive hit can cause significant loss of time and resources. Here, we present an instructive an...
