A series of 2(3H)‐thiazole thiones 3–5 was synthesized and evaluated for tyrosinase inhibition and DPPH radical scavenging activities. Among them, 3‐methyl‐4‐phenyl‐2(3H)‐thiazole thione (4a) showed good tyrosinase inhibitory activity, even better than that of the well‐known tyrosinase inhibitor, namely, kojic acid. From the structure–activity point of view, although it was found that the phenolic
合成了一系列 2(3H)-噻唑硫酮 3-5,并评估了酪氨酸酶抑制和 DPPH 自由基清除活性。其中,3-甲基-4-苯基-2(3H)-噻唑硫酮(4a)显示出良好的酪氨酸酶抑制活性,甚至优于众所周知的酪氨酸酶抑制剂曲酸。从结构-活性的角度来看,虽然发现原型 3-5 中的酚羟基可能有助于清除 DPPH 自由基,但酪氨酸酶抑制的效力与酚部分的存在之间没有相关性. 计算机模拟 ADME-Tox 筛选显示,最有效的化合物 4a 的药物相似性和药物评分值显着高于曲酸。
