A series of 4-butyl-5-(4-alkoxyphenyl)-2H-1,2,4-triazole-3(4H)-ones (6a-6u) was designed and synthesized.
The anticonvulsant effects and neurotoxicity of the compounds were evaluated with maximal electroshock test and rotarod
test. Among the synthetic compounds, 4-butyl-5-(4-(2-fluorinebenzyl)phenyl)-2H-1,2,4-triazole-3 (4H)-one (6k) was the
most potent with ED50 value of 27.4 mg/kg and protective index (PI = TD50/ED50) value of 12.0. Besides the anti-MES efficacy,
the potency of compound 6k against seizures induced by pentylenetetrazole (PTZ), 3-mercaptopropionic acid (3-
MP), and bicuculline (BIC) was also established, which suggested that the mechanisms of action including enhancing of
GABAergic activity might be involved in its anticonvulsant activity.
设计并合成了一系列4-丁基-5-(4-烷氧基苯基)-2H-1,2,4-三唑-3(4H)-酮(6a-6u),并通过最大电击试验和旋转体试验评估了这些化合物的抗惊厥作用和神经毒性。在合成的化合物中,4-丁基-5-(4-(2-氟苄基)苯基)-2H-1,2,4-三唑-3 (4H)-酮(6k)的药效最强,ED50 值为 27.4 mg/kg,保护指数(PI = TD50/ED50)值为 12.0。除了抗 MES 的药效外,化合物 6k 对戊烯四唑(PTZ)、3-巯基丙酸(3-MP)和双谷氨酸(BIC)诱导的癫痫发作也有很强的抑制作用,这表明其抗惊厥活性可能涉及包括增强 GABA 能活性在内的作用机制。
