dbco-nhs ester 2

DBCO-NHS ester 2 is a cleavable linker used in the synthesis of antibody-drug conjugates (ADCs) and is a Dibenzylcyclooctyne (DBCO) derivative designed for copper-free click chemistry [1].

DBCO-NHCO-PEG4-NHS ester ester is a MMP-2- and cathepsin B- (CatB) cleavable ADC linker used in the synthesis of antibody-drug conjugates (ADCs)[1].

DBCO-NHCO-PEG2-NHS ester, a PEG-based PROTAC linker, enables the synthesis of 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].

N-DBCO-N-bis(PEG2-C2-NHS ester) is a PEG-like PROTAC linker that can be used to synthesize PROTAC molecules, and also contains a DBCO moiety for click chemistry with azide groups.
