Inhibitor structure-guided design and synthesis of near-infrared fluorescent probes for monoamine oxidase A (MAO-A) and its application in living cells and in vivo

A series of near-infrared fluorescent probes based on inhibitor (clorgyline) structure-guided design were synthesized for the specific detection of MAO-A in cells and in vivo. Moreover, we have successfully used the high specificity of one of the probes to visualize MAO-A activity in zebrafish and tumor tissue for the first time.
