This study reports depigmenting potency of 1,3-selenazol-4-one derivatives, which would be based upon the finding of direct inhibition to mushroom tyrosinase. 1,3-Selenazol-4-one derivatives exhibited inhibitory effect on dopa oxidase activity of mushroom tyrosinase. In this study, inhibitory effects of six kinds of 1,3-selenazol-4-one derivatives (A, B, C, D, E and F) on mushroom tyrosinase were investigated. Compounds at a concentration of 500 μM exhibited 33.4—62.1% of inhibition on dopa oxidase activity of mushroom tyrosinase. Their inhibitory effects were higher than that of kojic acid (31.7%), a well known tyrosinase inhibitor. 2-(4-Methylphenyl)-1,3-selenazol-4-one (A) exhibited the strongest inhibitory effect among them dose-dependently and in competitive inhibition manner.
这项研究报告了 1,3-selenazol-4-one 衍生物的脱色功效,该研究基于对蘑菇酪氨酸酶的直接抑制作用的发现。 1,3-Selenazol-4-one衍生物对蘑菇酪氨酸酶的多巴氧化酶活性具有抑制作用。本研究研究了六种1,3-硒唑-4-酮衍生物(A、B、C、D、E和F)对蘑菇酪氨酸酶的抑制作用。浓度为500 μM的化合物对蘑菇酪氨酸酶多巴氧化酶活性的抑制率为33.4%~62.1%。它们的抑制效果高于众所周知的酪氨酸酶抑制剂曲酸(31.7%)。其中2-(4-甲基苯基)-1,3-硒唑-4-酮(A)表现出最强的抑制作用,且呈剂量依赖性和竞争性抑制方式。
