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-PEG2-NHS ester, a PEG-based PROTAC linker, enables the synthesis of PROTACs[1].

DBCO-NH-PEG7-C2-NHS ester is a polyethylene glycol (PEG) derived linker with a terminal DBCO moiety, functioning as an N-hydroxysuccinimide (NHS) ester, and suitable for the efficient synthesis of proteolysis-targeting chimeras (PROTACs)[1].

DBCO-PEG2-NHS ester is a click chemistry reagent featuring an azide group and an NHS ester, designed for copper-free Click Chemistry. It specifically and efficiently reacts with primary amines (e.g., lysine residue side chains or aminosilane-coated surfaces) under neutral or slightly basic conditions to form stable covalent bonds. The inclusion of a hydrophilic PEG spacer enhances water solubility and provides a flexible linkage, reducing steric hindrance during ligation. This compound, intended for research use only [1], is ideal for applications requiring precise and efficient bioconjugation.

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-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.
