Ligand for Target Protein for PROTAC

Targeted protein degradation (TPD) is attracting substantial interest owing to its potential to therapeutically modulate proteins that have proved difficult to target with conventional small molecules. A major class of molecules that may enable such proteins to be modulated through TPD are known as proteolysis-targeting chimera (PROTAC) protein degraders. These are heterobifunctional small molecules consisting of two ligands joined by a linker: one ligand recruits and binds a protein of interest (POI) while the other recruits and binds an E3 ubiquitin ligase.
