A series of 1-methyl-7-(4-pyridyl)-5,6,7,8-tetrahydro-3(2H)-isoquinolinones and related compounds were synthesized and evaluated for positive inotropic activity. Most members of this series exerted a dose-dependent increase in myocardial contractility in the dog acute heart failure model, whereas they caused only slight changes in heart rate and blood pressure. Several derivatives, especially those
合成了一系列的1-甲基-7-(4-吡啶基)-5,6,7,8-四氢-3(2H)-异喹啉酮和相关化合物并评估了其正性肌力活性。该系列的大多数成员在犬急性心力衰竭模型中使心肌收缩力呈剂量依赖性增加,而它们仅引起心率和血压的轻微变化。几种衍生物,特别是那些在4位上具有氰基,乙酰基和乙基取代基的衍生物,比用作参考的米力农更有效。4-乙酰基-1-甲基-7-(4-吡啶基)-5,6,7,8-四氢-3(2H)-异喹啉酮(MS-857)是该系列中最有效的正性肌力药物之一。
