Novel Ligands Control Metal Geometry for Enhanced Peptide Therapeutics

Many peptide-based drugs suffer from poor stability or non-specific interactions in biological systems, limiting their therapeutic potential. Metal ions are often crucial for the function of metalloenzymes or can be used in radiopharmaceuticals and imaging agents. However, controlling the precise coordination environment of these metals is challenging. This study explores how specialized tripodal ligands can enforce a specific trigonal prismatic geometry around a central metal ion, potentially improving the efficacy and selectivity of metal-containing biomolecules.
