The invention pertains to a functionalizable and enzyme-activatable fluorescent probe and methods for monitoring the activity of amine oxidases. Amine oxidases catalyze the oxidative deamination, e.g. of the ε-amine of a lysine to an aldehyde which in turn can form covalent bonds with neighboring side chains, e.g. in the context of collagen cross-linking. Amine oxidase activity can be correlated with collagen-associated diseases including pulmonary and hepatic fibrosis, cardiomyopathy and tumor metastasis.
