(Tox). The results showed that 5-(3-(trifluoromethyl)benzyl)-[1,2,4]triazolo[3,4-a]phthalazin-6(5H)-one (6e) had the most potent anticonvulsant activity with an ED50 value of 6.8 mg/kg and protective index (PI = TD50/ED50) value of 11.5 (i.p.); its anticonvulsant activity was found to be stronger than that of the lead compound and the standard drug carbamazepine. In particular, compound 6e protected
合成了一系列带有三唑(6a – y)和其他杂环取代基(8a – b,9a – b,10a – b,12a – b和14a – b)的2,3-二氢邻苯二甲酰1,4-二酮衍生物。及其结构的特征在于使用IR,1 H-NMR,13 C-NMR和MS。使用最大电击测试评估其抗惊厥活性,并使用旋转脚架神经毒性测试(Tox)评估其神经毒性。结果表明5-(3-(三氟甲基)苄基)-[1,2,4]三唑[3,4-a ] phthalazin-6(5 H)-one(6e)具有最强的抗惊厥活性,ED 50值为6.8 mg / kg,保护指数(PI = TD 50 / ED 50)为11.5(ip);发现其抗惊厥活性强于先导化合物和标准药物卡马西平。尤其是,化合物6e可以防止戊四唑和双瓜氨酸引起的癫痫发作。
