What is Propargyl-PEG8-NHS ester?
Description
Propargyl-PEG8-NHS ester is an amine reactive compound with an alkyne group. The alkyne group reacts with azide-containing biomolecules in Click Chemistry reactions, copper is needed as a catalyst. The hydrophilic PEG units helps the compound to have better solubility in aqueous environment.
Biological Activity
Propargyl-PEG8-NHS ester is a PROTAC bridge, belonging to the PEG class and the Alkyl/ether class. It can be used to synthesize a range of PROTAC molecules. And it is a cleavable ADC linker for 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.
