合成了一系列的1,2,3,4-四氢异喹啉衍生物,并评估了其对小鼠脑室内(icv)N-甲基-D-天冬氨酸(NMDA)诱导的惊厥的抗惊厥活性。在这些化合物中,(+)-1-甲基-1-苯基-1,2,3,4-四氢异喹啉盐酸盐((+)-1a,FR115427)是最有效的抗惊厥药,也可以保护CA1海马神经元免受缺血-诱导大鼠在32 mg / kg ip时神经元变性。此外,(+)-1a在3.2-32 mg / kg ip时在小鼠中表现出抗缺氧活性。确定异喹啉环C-1位置的绝对构型为通过(+)-1a(+)-二-对甲苯甲酰基-D-酒石酸酯的单晶X射线分析确定S为S. 讨论了有关该系列化合物抗惊厥活性的构效关系,
