In an attempt to search for more potent positive inotropic agents, two series of [1,2,4]triazolo[4,3-a] quinoxaline derivatives bearing substituted benzylpiperazine and benzoylpiperazine moieties were synthesized and their positive inotropic activities evaluated by measuring left atrial stroke volume in isolated rabbit heart preparations. Several compounds showed favorable activities compared with
为了寻找更有效的正性肌力药物,合成了两个系列的 [1,2,4] 三唑并 [4,3-a] 喹喔啉衍生物,这些衍生物带有取代的苄基哌嗪和苯甲酰哌嗪部分,并通过测量左心房来评估它们的正性肌力活性离体兔心脏制剂的每搏输出量。与标准药物米力农相比,几种化合物显示出良好的活性。化合物 6c 是最有效的药物,在 3 × 10-5 M 时每搏输出量增加 12.53% ± 0.30%(米力农:2.46% ± 0.07%)。还评估了具有相当强心力作用的化合物的变时作用。
