Nuclear magnetic resonance (NMR) spectroscopy is a pivotal method for structure-based and fragment-based lead discovery because it is one of the most robust techniques to provide information on protein structure, dynamics and interaction at an atomic level in solution. Nowadays, in most ligand screening cascades, NMR-based methods are applied to identify and structurally validate small molecule binding. These can be high-throughput and are often used synergistically with other biophysical assays. Here, we describe current state-of-the-art in the portfolio of available NMR-based experiments that are used to aid early-stage lead discovery. We then focus on multi-protein complexes as targets and how NMR spectroscopy allows studying of interactions within the high molecular weight assemblies that make up a vast fraction of the yet untargeted proteome. Finally, we give our perspective on how currently available methods could build an improved strategy for drug discovery against such challenging targets.

In this contribution, the latest developments in solid state NMR are presented in the field of organic-inorganic (O/I) materials (or hybrid materials). Such materials involve mineral and organic (including polymeric and biological) components, and can exhibit complex O/I interfaces. Hybrids are currently a major...

Abstract
Introduction: Nuclear magnetic resonance (NMR) applications in drug discovery are classified into two categories: ligand-based methods and protein-based methods. The latter is based on the observation of the (1)H-(15)N HSQC spectra of a protein with and without lead compounds. However, in order to take this...

Abstract
Nuclear Magnetic Resonance (NMR) relaxation is a powerful technique that provides information about internal dynamics associated with configurational energetics in proteins, as well as site-specific information involved in conformational equilibria. In particular, (15)N relaxation is a useful probe to...

Authors: Vogtherr M, Fiebig K
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...

PCS-based structure determination of proteinâ??protein complexes
Abstract A simple and fast nuclear magnetic resonance method for docking proteins using pseudo-contact shift (PCS) and 1HN/15N chemical shift perturbation is presented. PCS is induced by a paramagnetic lanthanide ion that is attached to a target protein using a lanthanide binding peptide tag anchored at two points. PCS provides long-range (~40 Ã?) distance and angular restraints between the lanthanide ion and the observed nuclei, while the 1HN/15N chemical shift perturbation data provide loose contact-surface information. The usefulness of this method was demonstrated through the structure...
