(4a, b) and benzotriazole (5a, b) rings, opening of the benzimidazolone ring (7) and substitution of the 1,2,3-triazole ring with a 2-hydroxyphenyl ring (10). Furthermore a series of 3-aryl-benzotriazin-4-one derivatives (13a-e) has been studied, which appears as a modification and/or combination of the benzimidazolone and benzotriazole rings. Only compound 10 shows interesting activity, while the other
本文报道了通过1,2,3-三唑基-苯并三唑和1,2,3-三唑基-苯并咪唑啉酮的结构修饰获得的一些化合物的合成和药理学评价,这些化合物已显示出作为大电导钙的潜在活化剂的活性。激活的钾离子通道(BK(Ca))。变化涉及在苯并咪唑酮(4a,b)和苯并三唑(5a,b)环的5位引入阻位取代基,苯并咪唑酮环(7)的开环和1,2,3-三唑的取代环带有2-羟基苯基环(10)。此外,已经研究了一系列3-芳基-苯并三嗪-4-酮衍生物(13a-e),其表现为苯并咪唑酮和苯并三唑环的修饰和/或组合。只有化合物10显示出有趣的活性,而其他结构修饰不会增加(化合物4和5)或降低(化合物7和13)药理活性。但是,这些结果提供了有关结构-活性关系的有用信息。
