Azido-PEG3-SS-PEG3-azide is a PEG-based PROTAC linker designed for use in the synthesis of PROTACs. This compound functions as a click chemistry reagent, featuring an Azide group that can participate in copper-catalyzed azide-alkyne cycloaddition (CuAAc) reactions with molecules containing Alkyne groups. Additionally, it can engage in strain-promoted alkyne-azide cycloaddition (SPAAC) reactions with molecules containing DBCO or BCN groups. PROTACs themselves are agents that utilize the intracellular ubiquitin-proteasome system to selectively degrade target proteins.

m-PEG3-succinimidyl carbonate is a PEG-based PROTAC linker that can be used in the synthesis of PROTACs. 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.
