DBCO-PEG1-amine is a PEG linker which contains DBCO and amine moieties. The DBCO group is commonly used in copper-free Click Chemistry reactions. The amine group is reactive with carboxylic acids, activated NHS esters, carbonyls (ketone, aldehyde) etc.
DBCO-PEG1-amine is a PEG-based PROTAC linker that can be used in the synthesis of PROTACs[1]. DBCO-PEG1-amine is a click chemistry reagent, it contains a DBCO group that can undergo strain-promoted alkyne-azide cycloaddition (SPAAC) with molecules containing Azide groups.
