However, since the early 2000s, there has been a sharp increase in the number of peptides entering clinical trials and gaining approval , supported by advances in peptide synthesis and a better understanding of their pharmacological properties. This review will illustrate how, today, AMP research benefits from advances in both experimental and computational tools, enabling a transition from serendipitous discoveries to structure-guided rational design. In addition, the discovery of novel AMPs can take advantage of the co-evolution between AMPs and bacteria, and use these structural scaffolds to obtain novel peptide drugs . The integrated use of experimental and computational approaches provides a powerful framework for exploring AMP structure and function, offering the potential to drive the discovery of new, effective antimicrobial treatments.
