A series of 1-heteroaroylpiperazines (V-VII, XI) was synthesized and examined for positive inotropic activities on the canine heart. The key intermediates, heteroarenecarboxylic acids (III, X), were prepared by two different methods, and were condensed with substituted piperazines to give 1-heteroaroylpiperazines V-VII and XI. Among them, quinazoline derivatives (XI) were found to have potent positive inotropic activities.
合成了一系列1-杂芳基哌嗪(V-VII, XI),并对其在犬心脏上的正性肌力活性进行了研究。关键中间体杂芳基羧酸(III, X)采用两种不同的方法制备,并与取代哌嗪缩合,得到1-杂芳基哌嗪V-VII和XI。其中,喹唑啉衍生物(XI)被发现具有强的正性肌力活性。
