Fluorescent probes for detecting monoamine oxidase activity and cell imaging
A series of new fluorogenic probes for monoamine oxidases (MAOs) were reported based on an oxidation and β-elimination mechanism. The limits of detection of the probes for MAO-A and -B were determined to be 3.5 and 6.0 μg mL−1 respectively. These probes displayed strong activity towards MAOs, especially MAO-B. Cellular imaging studies were also successfully conducted with MCF-7 cells.
