Ethyl azetidine-3-carboxylate hydrochloride is a non-cleavable ADC linker used in the synthesis of antibody-drug conjugates (ADCs). Ethyl azetidine-3-carboxylate hydrochloride is also a alkyl chain-based PROTAC linker that can be used in the synthesis of PROTACs[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].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
