Propargyl-PEG4-O-C1-NHS ester 

Propargyl-PEG4-O-C1-NHS ester (compound 8) is a PEG-based PROTAC linker can be used in the synthesis of PROTACs. Propargyl-PEG4-O-C1-NHS ester is a click chemistry reagent, it contains an Alkyne group and can undergo copper-catalyzed azide-alkyne cycloaddition (CuAAc) with molecules containing Azide groups.

PROTACs contain two different ligands connected by a linker; one is a ligand for an E3 ubiquitin ligase and the other is for the target protein. PROTACs exploit the intracellular ubiquitin-proteasome system to selectively degrade target proteins.
