Solution NMR Spectroscopy in Target-Based Drug Discovery.

Area of Science:

• Biochemistry
• Structural Biology
• Medicinal Chemistry

Background:

• Solution Nuclear Magnetic Resonance (NMR) spectroscopy enables the study of protein structure and dynamics under physiological conditions.
• NMR provides critical protein-ligand binding information essential for target-based drug discovery projects.
• The role of NMR in drug discovery is expanding across various stages of the process.

Purpose of the Study:

• To review the multifaceted roles of NMR spectroscopy in modern drug discovery.
• To highlight challenges and provide examples of NMR applications in target-based drug discovery.
• To explore the potential of in-cell NMR spectroscopy for assessing target engagement.

Main Methods:

• Ligand-observed and protein-observed NMR spectroscopy for fragment screening and affinity assessment.
• Integration of NMR with other biophysical techniques for structure-based drug design.
• Application of NMR for mapping ligand-binding sites and identifying hits.

Main Results:

• NMR effectively screens fragments with low binding affinities in fragment-based drug discovery.
• NMR aids in optimizing fragments into drug-like molecules.
• NMR provides detailed information on ligand binding affinities and binding site interactions.

Conclusions:

• NMR spectroscopy is a powerful and increasingly important tool throughout the drug discovery pipeline.
• NMR facilitates hit identification, affinity ranking, and binding site characterization.
• Future applications of NMR, including in-cell NMR, hold promise for advancing drug discovery, particularly in target engagement.
