Background:

Azido-PEG4-C2-acid a PEG-based PROTAC linker can be used in the synthesis of vRucaparib-TP4. Azido-PEG4-C2-acid is also a non-cleavable 4 unit PEG ADC linker used in the synthesis of antibody-drug conjugates (ADCs).

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.
