Skin color is determined by the amount of melanin and tyrosinase is a key enzyme of melanin synthesis. MITF(Microphthalmia-associated transcription factor) belongs to the basic helix-loop-helix-zip family of transcription factors and is the major regulator of tyrosinase and other related enzymes(TRPs). To screen depigmenting agents by HTS(highthroughput screening), a protein chip containing recombinant MITF protein was constructed. Based on the computer-simulated structure, 27 chemicals were selected and were investigated as MITF-DNA binding inhibitors. Among them, compound #18 was found to show the most potent inhibitory activity against MITF-DNA binding. To confirm its inhibitory activity against MITF-DNA binding, an Electrophoretic Mobility Shift Assay (EMSA) was performed. As a result, intensities of MITF-DNA bands were dose-dependently reduced by compound #18. In addition, nuclear extracts of fibroblasts and melanocytes were compared by EMSA for investigating the specific binding between the MITF-DNA of melanocytes and compound #18. Compound #18 did not show any effect on fibroblasts. Therefore, compound #18 could be used as a specific MITF-DNA binding inhibitor on melanocytes.
