propargyl-peg2-tos

Propargyl-PEG2-Tos 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.

Tos-PEG2-O-Propargyl is a polyethylene glycol (PEG)-based proteolysis targeting chimera (PROTAC) linker, commonly employed for the synthesis of Thalidomide-O-PEG2-propargyl[1].
