following COMT‐catalyzed 8‐O‐methylation. The newly developed two‐photonfluorescent 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

Among all of the derivatives tested, the most powerful antioxidant was 4-carboxymethyl daphnetin (compound 9), for which the strongest antioxidant activity was observed in all of the assays. In addition, compound 9 also displayed strong pharmaceutical properties in the form of metabolic stability. To summarize, compound 9 holds great potential to be developed as an antioxidant agent with excellent antioxidant
