DBCO-(PEG)3-VC-PAB-MMAE is a chemical compound where monomethyl auristatin E (MMAE), a potent tubulin inhibitor acting as a toxin payload in antibody-drug conjugates, is conjugated to a DBCO-(PEG)3-vc-PAB linker.
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].
