英文摘要A practical two-photon fluorescent probe was developed for highly sensitive and selective sensing of the activities of catechol-O-methyltransferase (COMT) in complex biological samples. To this end, a series of 3-substituted 7,8-dihydroxycoumarins were designed and synthesized. Among them, 3-BTD displayed the best combination of selectivity, sensitivity, reactivity, and fluorescence response following COMT-catalyzed 8-O-methylation. The newly developed two-photon fluorescent probe 3-BTD can be used for determining the activities of COMT in complex biological samples and bio-imaging of endogenous COMT in living cells and tissue slices with good cell permeability, low cytotoxicity, and high imaging resolution. All these findings suggest that 3-BTD holds great promise for developing therapeutic molecules that target COMT, as well as for exploring COMT-associated biological processes and its biological functions in living systems. Furthermore, the strategy also sheds new light on the development of fluorescent probes for other conjugative enzymes.
