cis-4-Hydroxy-L-proline hydrochloride is acleavableADC linker used in the synthesis ofantibody-drug conjugates (ADCs). cis-4-Hydroxy-L-proline hydrochloride is also a PEG-based PROTAC linker that can be used in the synthesis ofPROTACs^[1][2].

ADCs are comprised of an antibody to which is attached an ADC cytotoxin through an ADC linker^[1].
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^[2].
