A series of novel 7-(benzylamino)-1H-benzo[b][1,4]diazepine-2,4(3H, 5H)-dione derivatives were synthesized and screened for their anticonvulsant activities by the maximal electroshock (MES) test, subcutaneous pentylenetetrazol (scPTZ) test, and their neurotoxicity was evaluated by the rotarod neurotoxicity test (Tox). The study showed that the compound 8c (7-(4-fluorobenzylamino)-1,5-dimethyl-1H-benzo[b][1
合成了一系列新型的7-(苄氨基)-1 H-苯并[b] [1,4]二氮杂-2,4(3 H,5 H)-二酮衍生物,并通过最大电击筛选其抗惊厥活性。 MES),皮下戊四氮(scPTZ)测试,并通过旋转脚神经毒性测试(Tox)评估其神经毒性。研究表明,化合物8c(7-(4-氟苄氨基)-1,5-二甲基-1 H-苯并[b] [1,4]二氮杂-2,4(3 H,5 H)-二酮)为是最有前途的化合物,在MES测试中,平均有效剂量(ED 50)为36.5 mg / kg,保护指数(PI)值为4.5。在scPTZ测试中,化合物8c也表现出更好的抗惊厥活性(ED 50 = 68.2 mg / kg),并且化合物8c的ED 50值小于参考抗癫痫药卡马西平(ED 50 > 100 mg / kg),苯妥英钠(ED 50 > 300 mg / kg)和丙戊酸钠(ED 50 = 149 mg / kg)。讨论了可能的结构活性关系。
