Introduction of 1347750-80-4 :

Propargyl-PEG4-thiol is a PEG-based PROTAC linker can be used in the synthesis of PROTACs. Propargyl-PEG4-thiol is a non-cleavable ADC linker used in the synthesis of antibody-drug conjugates (ADCs)[1]. Propargyl-PEG4-thiol is a click chemistry reagent, itcontains an Alkyne group and can undergo copper-catalyzed azide-alkyne cycloaddition (CuAAc) with molecules containing Azide groups. In Vitro: 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.
ADCs are comprised of an antibody to which is attached an ADC cytotoxin through an ADC linker.
