one-tenth the potency of compound 1. Both compounds 1 and 15 demonstrated direct inotropic and vasodilatory effects when administered iv in anesthetized dogs, although the vasodilatory activity was more pronounced with compound 15 than 1 and DPI compound. Compound 1 lacks the CN moiety which is a key structural requirement in DPI for positive inotropic activity. The synthesis, in vitro, and in vivo evaluations
合成了一系列的4-(二苯甲基)-α-[(4-喹啉基氧基)甲基] -1-管嗪乙醇及其密切相关的化合物,并评估了离体灌流大鼠和豚鼠心脏的心脏和血管活性。与豚鼠心脏相比,化合物1在大鼠心脏中产生的正性肌力作用更大,这种现象在原型药物DPI 201-106中也观察到。化合物15产生的肌力作用为化合物1的十分之一。当在麻醉犬中静脉给药时,化合物1和15都表现出直接的肌力作用和血管舒张作用,尽管化合物15的血管舒张活性比1和DPI化合物更为明显。化合物1缺少CN部分,这是DPI中正性肌力活性的关键结构要求。体外合成
