N-(t-Boc-Aminooxy-PEG2)-N-bis(PEG3-propargyl) is a PEG-based PROTAC linker that can be used in the synthesis of PROTACs[1]. N-(t-Boc-Aminooxy-PEG2)-N-bis(PEG3-propargyl) 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[1].
