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。
