Introduction of 77449-94-6 :

cis-4-Hydroxy-D-proline hydrochloride is a non-cleavable ADC linker used in the synthesis of antibody-drug conjugates (ADCs). cis-4-Hydroxy-D-proline hydrochloride is also a alkyl chain-based PROTAC linker that can be used in the synthesis of PROTACs[1][2]. In Vitro: 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].
