A series of 4-phenoxy-2-(1-piperazinyl)quinazolines was synthesized and examined for anticonvulsive and antihypoxic activities. Many of the compounds exhibited potent anticonvulsive activity comparable to that of carbamazepine or phenytoin. Among them, 4-phenoxy-2-(4-propyl-1-piperazinyl)quinazoline (5w) was selected as the most promising candidate antiepileptic drug with few side effects. It seemed that potent anticonvulsive activity was a prerequisite for potent antihypoxic activity.
一系列4-苯氧基-2-(1-哌嗪基)喹唑啉被合成并测试了其抗惊厥和抗缺氧活性。许多化合物的抗惊厥活性与卡马西平或苯妥英相当。其中,4-苯氧基-2-(4-丙基-1-哌嗪基)喹唑啉(5w)因其较少的副作用而成为最有前景的抗癫痫药物候选。似乎强大的抗惊厥活性是获得强大抗缺氧活性的先决条件。
