The cellular environment can affect the structure and function of pharmacological targets and the interaction with potential drugs. Such complexity is often overlooked in the first steps of drug design, where compounds are screened and optimized in vitro, leading to high failure rates in the pre-clinical and clinical tests. In-cell NMR spectroscopy has the potential to fill this gap, as it allows structural studies of proteins and nucleic acids directly in living cells, from bacteria to human-derived, providing a unique way to investigate the structure and dynamics of ligand-target interactions in the native cellular context. When applied to drug screening, in-cell NMR provides insights on binding kinetics and affinity toward a cellular target, offering a powerful tool for improving drug potency at an early stage of drug development.
