synthesized as anticonvulsant agents. Conformational analysis and superimposition of energy minima conformers of the designed molecules on estazolam, a known benzodiazepine receptor agonist, revealed that the main proposed benzodiazepine pharmacophores were well matched. Electroshock and pentylenetetrazole-induced lethal convulsion tests showed that the introduction of an amino group in position 2 of 1
设计并合成了一系列新型的2-取代的5-(2-苄
硫基苯基)-1,3,4-恶二唑类作为抗惊厥剂。在已知的苯并二氮杂receptor受体激动剂estazolam上对所设计分子的构象分析和能量最小构象子的叠加表明,主要提出的苯并二氮杂药效基团很好地匹配。电击和
戊四唑诱导的致死惊厥试验表明,在1,3,4-恶二唑环的2位引入
氨基和在苄
硫基部分的对位引入
氟取代基具有最佳的惊厥活性。看来这种作用是通过苯并二氮杂receptor受体机制介导的。
