vasodilating/beta-adrenergic blocking agent 2-[4-[3-(tert-butylamino)-2-hydroxypropoxy]phenyl]-4-(trifluoromethyl)imidazole (1) has been investigated. Introduction of selected substitutents onto the imidazole ring, in place of the trifluoromethyl group, has yielded highly cardioselective beta-adrenergic blocking agents such as 7, 17, and 18. The placement of alkyl or chloro groups onto the aryl ring of 1, as illustrated
已经研究了血管扩张/β-肾上腺素能阻断剂2- [4- [3- [叔丁基氨基)-2-羟基丙氧基]苯基] -4-(三氟甲基)咪唑(1)的药理作用的改变。如图所示,将选定的取代基取代三氟甲基引入到咪唑环上,产生了高度心脏选择性的β-肾上腺素能阻断剂,例如7、17和18。如图所示,烷基或氯基在1的芳基环上的位置33岁时,已生产出一类以降压β-肾上腺素能阻断剂为特征的化合物。在这些例子中,急性降压活性似乎不是由于血管舒张或β2-激动剂性质引起的。
