Boc-PEG4-acid is a PEG-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-(Azido-PEG2)-N-Boc-PEG4-acid is a polyethylene glycol (PEG)-based linker specifically designed for the synthesis of PROteolysis TArgeting Chimeras (PROTACs)[1].
