The synthesis and biological evaluation of a series of novel 1-(aryloxy)-2-propanolamines and several related deshydroxy analogues are described. Compounds 4-29 were prepared and investigated for their class III electrophysiological activity in isolated canine Purkinje fibers and in anesthetized open-chest dogs. None of these compounds showed any class I activity. On the basis of the in vitro data
描述了一系列新型的1-(芳氧基)-2-丙醇胺和几种相关的脱羟基类似物的合成和生物学评估。制备了化合物4-29,并在分离的犬浦肯野纤维和麻醉的开胸狗中研究了它们的III类电生理活性。这些化合物均未显示出任何I类活性。基于体外数据,讨论了该系列的结构-活性关系。N- [4- [2-羟基-3- [甲基(2-喹啉基甲基)氨基]丙氧基]苯基]甲磺酰胺(12,WAY-123,223)和N- [2-[[甲基[3- [4]鉴定了[[[(甲基磺酰基)氨基]苯氧基]丙基]氨基]甲基] -6-喹啉基]-甲磺酰胺(24,WAY-125,971),并在体外和体内鉴定为有效的和特定的III类抗心律不齐药物。已发现化合物12具有口服生物利用度,可大幅提高心室纤颤阈值(VFT),并且在某些情况下,以5 mg / kg的剂量在麻醉的开胸狗中可恢复室颤的窦性心律(iv )。合成了12个对映体(即13和14),并在Purkin
