Application

Water soluble succinimidyl ester/NHS functionalized cyclooctyne derivative for incorporation of the cyclooctyne moiety into amine containing compounds or biomolecules. Cyclooctynes are useful in strain-promoted copper-free azide-alkyne cycloaddition reactions. This dibenzocyclooctyne will react with azide functionalized compounds or biomolecules without the need for a Cu(I) catalyst to result in a stable triazole linkage.
Dibenzocyclooctyne-sulfo-N-hydroxysuccinimidyl ester may be used for the covalent modification of nano-sized metal-organic frameworks (NMOFs) with nucleic acids via click chemistry during the synthesis stimuli-responsive DNA-gated NMOFs. These NMOFs can act as carriers of a fluorescent agent or anticancer drug, making them highly useful in targeted drug release system.
