A systematic structure-activity exploration of the carboxylic acid region in a series of indole- or indazole-derived leukotriene antagonists 1 led to several discoveries. Use of the 3-methoxy-p-tolyl fragment (illustrated in acid 1) for connecting the indole and the acidic site provides the most potent carboxylic acids 1, tetrazoles 20, and aryl sulfonimides 21. The aryl sulfonimides are 5-500 times
对一系列由吲哚或吲唑衍生的白三烯拮抗剂1的羧酸区域进行系统的结构活性探索导致了一些发现。使用3-甲氧基对甲苯基片段(如酸1中所示)连接吲哚和酸性位点可提供最有效的羧酸1,四唑20和芳基磺酰亚胺21。芳基磺酰亚胺的含量是5-500倍以上(在体外和/或体内)比相应的羧酸更有效。在给定的体外活性水平下,邻甲苯基磺酰亚胺(如114)显示出比苯基磺酰亚胺更大的口服效力。酸性酮砜衍生物10(Nu = CH-(CO2CH3)SO2Ph)模拟了磺酰亚胺的活性。
