Abstract:

Ver-nohia anthelmintica L was endemic plant in Xinjiang, which was often used in the treatment of Vitiligo. It was believed that the chalcone compounds of Ver-nohia anthelmintica L played an important role in this treatment. Since it may activate tyrosinase and improve the melanin production, many chalcone compounds and derivatives were described as potential inhibitor on tyrosinase which may act as skin lightening and whitening agents. However, chalcones which showed activator effect were seldom reported. In order to search for chalcones with high activities on tyrosinase, eight novel chalcone derivatives containing benzothiazole and eight amide-derived chalcones were synthesized in this work. All the compounds were idenpngied by 1H NMR, 13C NMR, IR, HRMS and evaluated their activator effect on tyrosinase by measuring the oxidation rate of L-dopa. Compared with the reference drug 8-methoxypsoralen, compounds 4d, 4h, 5d, 7b and 7d showed some activator effect on tyrosinase. Amomg them, compound 7d demonstrated more potent activity with EC50=9.6 μmol/L than 8-methoxypsoralen, which EC50 value was 14.8 μmol/L. Further structural modification of this novel chalcones containing benzothiazole will be required for improving the solubility of them.

Key words: Chalcone, Benzothiazole, Amide, Activity on tyrosinase
