5-phenylhydantoins with the anticonvulsant site on the neuronal voltage-sensitive sodium channel, two isomeric hydantoins containing conformationally constrained phenyl rings and their monocyclic analogues were synthesized. One, a spirohydantoin (2) derived from alpha-tetralone, contains the plane of the phenyl ring in an orientation approximately perpendicular to that for the hydantoin ring. The other, a tricyclic
作为对5-苯基乙内酰脲与神经元电压敏感钠通道上抗惊厥位点相互作用的芳香环取向的重要性的初步研究,合成了两个含有构象受限的苯环的异构体乙内酰脲及其单环类似物。一种是衍生自α-四氢萘酮的螺乙内酰脲(2),其苯环平面的方向与乙内酰脲环的方向近似垂直。另一个是衍生自四氢异喹啉的三环乙内酰脲(4),其苯环平面的方向与乙内酰脲环的平面大致共面。在钠通道结合和整个动物(小鼠)抗惊厥试验中评估了这些化合物。在这两种测定中,4的效力明显强于2。
