Phage display technology for target determination of small-molecule therapeutics: an update.

Despite the development of bioinformatics tools and artificial intelligence (AI)-mediated methods, affinity-guided information obtained experimentally are still indispensable to identify drug-protein interactions. By taking advantage of small-molecule-oriented PD methods and their improvements, the extension of the druggable proteome will be further expanded, providing new opportunities to generate small-molecule therapeutics.
