2-aryl-2-(2-piperidinyl)-4-[N,N-bis (1-methylethyl)amino] butanamides (2). Individual racemates of the piperidinyl amides 2 were converted to pure racemic diaza bicyclic compounds that were evaluated for antiarrhythmic activity in the Harris dog model and anticholinergic activity in a muscarinic receptor binding assay. Selected compounds were subsequently evaluated for hemodynamic effects in anesthetized
由2-芳基-2-(-)制备一系列4,4-二取代的四氢和4,4-二取代的六氢-3H-吡啶并[1,2-c]嘧啶-3-酮(分别为4和5)。 2-哌啶基)-4- [N,N-双(1-甲基乙基)氨基]丁酰胺(2)。哌啶基酰胺2的各个外消旋物被转化为纯的外消旋二氮杂双环化合物,该化合物在哈里斯犬模型中评估了抗心律失常活性,并在毒蕈碱受体结合试验中评估了其抗胆碱能活性。随后评估所选化合物在麻醉犬中的血流动力学作用,评估血压降低和负性肌力活性。在这一组中,4a(R = CH3)和5a(R = CH3)显示出最有利的药理作用;选择前一种化合物而不是后者进行毒性测试,是因为它缺乏对乙酰胆碱诱导的豚鼠回肠段收缩的非竞争性抑制作用。临床评估正在进行中。
