Mal-PEG1-Boc is a alkyl ether-based linker for PROTACs which joins two essential ligands, crucial for forming PROTAC molecules. This linker enables selective protein degradation by leveraging the ubiquitin-proteasome system within cells.
N-Mal-N-bis(PEG2-NH-Boc) is a polyethylene glycol (PEG) derived linker specifically designed for the synthesis of proteolysis targeting chimeras (PROTACs)[1].
