their in vitro xanthine oxidase (XO), tyrosinase and melanin production inhibitory activity. Most of the target compounds had more potent XO inhibitory activity than the standard drug (IC50 = 4.3–5.6 μM). Interestingly, compound 7q bearing cyclopropyl ring was found to be the most potent inhibitor of XO (IC50 = 4.3 μM). Molecular modelling study gave an insight into its binding modes with XO.

3-甲酰基-9-甲基咔唑与3-氨基苯乙酮的各种酰胺的Claisen-Schmidt缩合反应得到N- 3- [3-(3-(9-甲基-9 H-咔唑-3-基)-丙烯酰基]-丙烯基]苯基}-苯甲酰胺/酰胺衍生物。研究了所有化合物的体外黄嘌呤氧化酶(XO),酪氨酸酶和黑色素生成抑制活性。大多数目标化合物具有比标准药物更强的XO抑制活性(IC 50 = 4.3–5.6μM)。有趣的是,发现带有环丙基环的化合物7q是最有效的XO抑制剂(IC 50 = 4.3μM)。分子建模研究深入了解了其与XO的结合模式。化合物7a,7d,7e,7克和7K被发现是酪氨酸酶的强效抑制剂(IC 50 = 14.01-17.52μM)。这些结果表明这些化合物可能用于设计和开发新型XO和酪氨酸酶抑制剂。
