animals. A class of novel N-aryl-N′-substituted phenylthiourea derivatives (3a–i, 6a–k) were designed, synthesized and their inhibitory effects on the diphenolase activity of mushroom tyrosinase were evaluated. The results showed some 4,5,6,7-tetrahydro-2-[[(phenylamino)thioxomethyl]amino]-benzo[b]thiophene-3-carboxylic acid derivatives (3a–i) exhibited moderate inhibitory potency on diphenolase activity
酪氨酸酶是植物和动物体内黑色素生成过程中的关键酶。设计,合成了一类新型的N-芳基-N'-取代的苯硫脲衍生物(3a – i,6a – k),并评价了它们对蘑菇酪氨酸酶双酚酶活性的抑制作用。结果表明,某些4,5,6,7-四氢-2-[[[((苯基氨基)硫代甲基]氨基]-苯并[ b ]噻吩-3-羧酸衍生物(3a – i)对中和酚的双酚酶活性具有中等抑制作用。酪氨酸酶。当4,5,6,7-四氢苯并[ b用2-(1,3,4-噻二唑-2-基)硫代乙酸代替]噻吩-3-羧酸,化合物(6a - k)对酪氨酸酶的抑制作用明显提高。特别是化合物6h(IC 50 = 6.13μM)的抑制活性明显高于曲酸(IC 50 = 33.3μM)。此外,对抑制机理的分析表明,化合物6h可能起非竞争性抑制剂的作用。
