Innovations such as solid-phase peptide synthesis (SPPS), peptide stapling, and computational modeling have made it possible to design peptides with improved stability, bioavailability, and target affinity. The emergence of peptides and high-throughput screening platforms has also accelerated the discovery of new peptide sequences with therapeutic potential. As our understanding of peptide biology and engineering improves, the potential for peptides to drive innovation in drug discovery and development remains vast.
