Area of Science:

• Biochemistry
• Structural Biology
• Chemical Biology

Background:

• Nuclear magnetic resonance (NMR) spectroscopy is crucial for determining protein structure, dynamics, and interactions at atomic resolution in solution.
• NMR-based methods are widely used in ligand screening cascades for identifying and structurally validating small molecule binding.
• These techniques are often high-throughput and complement other biophysical assays.

Purpose of the Study:

• To review the current state-of-the-art NMR experiments for early-stage drug lead discovery.
• To highlight the application of NMR spectroscopy in studying interactions within multi-protein complexes.
• To provide a perspective on enhancing drug discovery strategies for challenging, high molecular weight targets.

Main Methods:

• Description of current state-of-the-art NMR experiments applicable to early-stage drug discovery.
• Focus on NMR techniques for analyzing interactions in multi-protein complexes.
• Discussion of NMR's role in studying high molecular weight assemblies.

Main Results:

• NMR provides robust atomic-level information on protein structure, dynamics, and interactions in solution.
• NMR methods are effective for high-throughput screening and validation of small molecule binding.
• NMR enables the study of complex interactions within large protein assemblies, a significant fraction of the proteome.

Conclusions:

• NMR spectroscopy is a powerful tool for structure-based and fragment-based lead discovery.
• NMR is essential for identifying and validating small molecule binders, particularly for challenging multi-protein targets.
• Advancements in NMR methods can significantly improve drug discovery strategies against previously untargeted proteomes.
