(4R,5S)-Nutlin Carboxylic Acid (MDM2 Ligand 2), a Nutlin 3-based MDM2 ligand, can be conjugated to a protein-binding ligand via a linker to create PROTACs[1].
N-(Amino-PEG5)-N-bis(PEG4-acid) is a PEG-based PROTAC linker employed for synthesizing PROTACs. It comprises an amino group with two terminal carboxylic acids[1].
Amino-PEG36-CONH-PEG36-acid is a polyethylene glycol (PEG)-based linker with amino and carboxylic acid functionalities. It finds utility in the synthesis of proteolysis targeting chimeras (PROTACs)[1].
DBCO-NHS ester 3 (Compound 12) is a cleavable linker utilized in the synthesis of antibody-drug conjugate (ADC). It is a derivative of Dibenzylcyclooctyne (DBCO) resulting from the activation of N-hydroxysuccinimide by the carboxylic acid moiety of both methyl-oxanorbornadiene (MeOND) and dibenzoazacyclooctyne (DIBAC)[1][2].
