What is Propargyl-PEG4-thiol?
Description
Propargyl-PEG4-thiol is a crosslinker containing a propargyl group and thiol group. The propargyl group can form triazole linkage with azide-bearing compounds or biomolecules via copper catalyzed Click Chemistry reactions. The thiol group reacts with maleimide, OPSS, vinylsulfone and transition metal surfaces including gold, silver, etc.
Biological Activity
Propargyl-PEG4-thiol is a PROTAC linker and belongs to the PEG class. It can be used to synthesize a series of PROTAC molecules. It is a non-cleavable ADC linker used in the synthesis of antibody drug conjugates (ADCs).
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.
