New PIFT Framework Transfers Peptide Interaction Patterns to Small Molecules for Drug Discovery

Researchers have developed PIFT (Peptide InterFace Transfer), a new framework designed to generate small molecules that can target protein-protein interactions (PPIs). This method addresses the challenge of transferring interaction patterns from peptides to small molecules by using a shared interaction space and joint guidance for diffusion and flow matching. PIFT maps both peptide-target and small-molecule-target interfaces into this common space, allowing for the transfer of interaction information. The framework then guides the generation of small molecules, ensuring they are compatible with peptide-derived constraints while maintaining a strong molecular prior, leading to improved interface recovery and docking performance.
