azido peg4 propargyl

Azido-PEG4-propargyl 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.

Azido-PEG3-S-PEG4-propargyl is a polyethylene glycol (PEG)-based linker that contains the azide group and propargyl functionality. This linker is designed specifically for the synthesis of proteolysis targeting chimeras (PROTACs)[1].
