described. These compounds are potent inhibitors of the 5-lipoxygenase from RBL-1 cells and also inhibit bovine seminal vesicle cyclooxygenase. Structure-activity relationships for these two enzymes are different, implying specific enzyme inhibition rather than a nonspecific antioxidant effect. 2-(Aryl-methyl)-1-naphthols are among the most potent 5-lipoxygenase inhibitors reported (IC50 values generally
描述了一系列在2-位带有碳取代基的1-萘的合成,生物学评估和结构-活性关系。这些化合物是来自RBL-1细胞的5-脂氧合酶的有效抑制剂,并且还抑制牛精囊泡加氧合酶。这两种酶的结构活性关系不同,这意味着特定的酶抑制作用而非非特异性的抗氧化作用。2-(芳基甲基)-1-萘酚是最有效的5-脂氧合酶抑制剂之一(IC50值通常为0.01-0.2 microM),在小鼠花生四烯酸耳水肿模型中显示出出色的抗炎作用。为了研究结构对体外和体内活性的影响,改变了该分子的四个一般特征:2-取代基,1-羟基,萘环上的取代基和1,2-二取代的萘单元本身。2-苄基-1-萘酚(5a,DuP 654)显示出极具吸引力的局部抗炎活性,目前正作为局部应用的银屑病药物进行临床试验。
