peg2cl

PEG2-Cl 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.

Thalidomide-5-PEG2-Cl, a Thalidomide-derived cereblon ligand, serves as the ligand for the recruitment of CRBN protein. It can be conjugated to the protein ligand via a linker to produce PROTACs.
