Azido-dPEG4-acid Structural

What is Azido-dPEG4-acid?

Description

Azido-PEG3-acid is a crosslinker containing an azide(N3) group with a carboxylic acid (CO2H). The terminal carboxylic acid is reactive with primary amine groups in the presence of activators (e.g. EDC, or HATU) forming a stable amide bond. The azide group enables Click Chemistry. The hydrophilic PEG spacer increases solubility in aqueous media.

Definition

ChEBI: 3-{2-[2-(2-Azidoethoxy)ethoxy]ethoxy}propanoic acid is an organonitrogen compound.

Biological Activity

Azido-dPEG4-acid is a PEG-based PROTAC linker for the synthesis of BI-3663 (HY-111546), BI-4216 and BI-0319. It is also a non-cleavable ADC linker containing 3-unit PEG, which can be used to synthesize antibody drug conjugates (ADC).

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.
