Bis-aminooxy-PEG4

Bis-aminooxy-PEG4 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-(Aminooxy-PEG3)-N-bis(PEG4-Boc) is a polyethylene glycol (PEG)-based linker primarily utilized in PROTAC synthesis for the development of proteolysis-targeting chimeras (PROTACs)[1].
