A new fluorescence-forming probe, coumOCT, designed by fusing cyclooctyne with a coumarin fluorophore was successfully used for the imaging of azido-glycoconjugates in living HeLa cells.
Provided are benzocyclooctyne compounds of formula (I). These compounds undergo strain-promoted azide-alkyne cyclo additions (SPAAC) without presence of toxic metal catalysts. The provided compounds are useful for diagnosis and imaging of azide-containing molecules. Methods for detection and imaging biomolecules using compounds of the present disclosure are disclosed.
