1-Boc-azetidine-3-carboxylic acid is a non-cleavable ADC linker used in the synthesis of antibody-drug conjugates (ADCs). 1-Boc-azetidine-3-carboxylic acid is also a alkyl chain-based PROTAC linker that can be used in the synthesis of PROTACs[1][2]

Target	Non-cleavable
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].
