N-(Biotin-PEG4)-N-bis(PEG4-Boc) is a PEG-based PROTAC linker that can be used in the synthesis of PROTACs[1].

N-(Biotin-PEG4)-N-bis(PEG4-Boc) is a PEG-based PROTAC linker that can be used in the synthesis of PROTACs[1]. PROTACs contain two different ligands connected by a linker; one is a ligand for an E3 ubiquitin ligase and the other is for the target protein. PROTACs exploit the intracellular ubiquitin-proteasome system to selectively degrade target proteins[1].
