DBCO-NHCO-PEG4-NHS ester 

DBCO-NHCO-PEG4-NHS ester is a PEG/Alkyl/ether-based PROTAC linker can be used in the synthesis of PROTACs. DBCO-NHCO-PEG4-NHS ester is a cleavable ADC linker used in the synthesis of antibody-drug conjugates (ADCs)^[1]. DBCO-NHCO-PEG4-NHS ester is a click chemistry reagent, it contains a DBCO group that can undergo strain-promoted alkyne-azide cycloaddition (SPAAC) with molecules containing Azide groups.

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.
