MITF, an E-Box (CATGTG) binding transcriptional factor, regulates expression of tyrosinase, which involves in melanin synthesis in the Melanocytes. To screen for MITF and E-box binding inhibitor, EMSA (Electrophoretic Mobility Shift Assay) was performed. Based on the computer-simulated structure, 27 chemicals were selected and were investigated as MITF and E-box binding inhibitors. After that, cell tests were performed by using the mean-a cell line. Among them, compound #18 was shoed the potent inhibitory activity against MITF and E-box binding. Pursuant to EMSA, intensities of MITF and E-box bands were reduced by compound #18 in a dose-dependent manner. In addition, unlabelled Tyr-p, mutated Tyr-p and random oligomer were used for EMSA to investigate the competitive binding inhibitory effect. As a result, excess unlabelled Tyr-p was an effective binding competitor. To confirm the above findings, the expression of tyrosinase was evaluated by western blot, in response to compound #18. It was found to be reduces level tyrosinase while MITF and TRP-1 remain unaffected. Therefore, compound #18 could be used as a specific MITF and E-box binding inhibitor, to reduce the melanin content in Melanocytes.
