is an important rate-limiting enzyme in melanin biosynthesis. To find potential tyrosinase inhibitors with anti-melanogenic activity, a series of indole-thiazolidine-2,4-dione derivatives 5a~5z were synthesized by incorporating indole with thiazolidine-2,4-dione into one compound and assayed for their biological activities. All compounds displayed tyrosinase inhibitory activities and 5w had the highest
酪氨酸酶是黑色素生物合成中重要的限速酶。为了寻找潜在的具有抗黑素活性的酪氨酸酶抑制剂,通过将吲哚与噻唑烷-2,4-二酮结合合成一系列吲哚-噻唑烷-2,4-二酮衍生物5a~5z,并测定其生物活性。所有化合物均表现出酪氨酸酶抑制活性,其中5w的抗酪氨酸酶抑制活性最高,IC50值为11.2 μM。抑制动力学表明 5w 是一种混合型酪氨酸酶抑制剂。荧光猝灭结果表明5w在静态过程中猝灭了酪氨酸酶的荧光。CD光谱和3D荧光光谱结果表明5w与酪氨酸酶的结合可以改变酪氨酸酶的构象和微环境。分子对接也代表了5w和酪氨酸酶之间的结合。此外,5w 可以抑制 B16F10 细胞和斑马鱼模型中的酪氨酸酶活性和黑色素生成。因此,化合物5w可以作为具有抗黑色素生成活性的酪氨酸酶抑制剂。
