再灌注(reperfusion)诱发心律不齐[心室心动过速(VI)和心脏震颤(VF)]在被麻醉的老鼠身上进行研究。心肌局部缺血是通过压迫左侧下行冠状动脉5分钟,停止压迫,而后再通过10分钟心脏再灌注而得出的。ECG得到持续监测,再灌注最初3分钟内在受试化合物影响下,VT和VF的平均持续时间的变化以及存活也得到测量。此受试化合物在压迫左侧下行冠状动脉前,以静脉内(i.v)剂量1mg/kg给药5分钟。使用例如实施例2和7的化合物时发现受试动物的存活率为100%。
这些化合物的血管弛缓效应在分离自兔子的胸主动脉上得到活体外观察[美国生理学杂志,257,1327~1333(1989)]。我们的结果总结于表1中。
