moiety in the parent compound 1a were also examined. Many of the compounds exhibited antiarrhythmic properties stronger than quinidine and procainamide, associated with a more favorable LD50/ED50 ratio. Compounds 1a (LR-18,460, 3-[2-[2-(diethylamino)ethoxy]phenoxy]-4-phenyl-3-buten-2-one) and 1h (LR-18,795, 3-[2-[3-(dimethylamino)propoxy]phenoxy]-4-phenyl-3-buten-2-one) were submitted to further antiarrhythmic
已合成了许多标题化合物(1)和一些相关的氢醌衍生物(2),并在体内和体外(抗CaCl2诱导的心室纤颤的保护作用)和体外(降低最大驱动力的能力)进行了抗心律不齐活性的测试。离体兔心房中电刺激的频率)。还研究了由母体化合物1a中的烯醇醚部分的改性引起的效果。许多化合物具有比奎尼丁和普鲁卡因酰胺更强的抗心律失常特性,并具有更有利的LD50 / ED50比。化合物1a(LR-18,460,3- [2- [2-(二乙基氨基)乙氧基]苯氧基] -4-苯基-3-丁烯-2-酮)和1h(LR-18,795,3- [2- [3- (二甲氨基)丙氧基]苯氧基] -4-苯基-3-丁烯-2-酮)进行进一步的抗心律失常试验,在所有实验中证实了它们对奎尼丁的有效性和优越性。经过安全性评估研究后,均选择了两者进行临床研究。
