4‐(3‐alkoxy‐phenyl)‐2,4‐dihydro‐[1,2,4]triazol‐3‐ones were synthesized using the appropriate synthetic route and evaluated experimentally in the maximal electroshock test; their neurotoxicities were evaluated by the rotarod neurotoxicity test. The structures of these compounds were confirmed by IR, MS, 1H‐NMR, and elementary analysis. All target compounds exhibited anticonvulsant activity to varying degrees in
使用适当的合成路线合成了一系列 4-(3-alkoxy-phenyl)-2,4-dihydro-[1,2,4]triazol-3-ones,并在最大电击试验中进行了实验评估;它们的神经毒性通过旋转棒神经毒性试验进行评估。这些化合物的结构经IR、MS、1H-NMR和元素分析确证。所有目标化合物在最大电击试验中均表现出不同程度的抗惊厥活性。4-(3-Benzyloxy-phenyl)-2,4-dihydro-[1,2,4]triazol-3-one (4i) 是最有前途的化合物,其 ED50 值为 30.5 mg/kg,具有保护指数( PI) 为 18.63,显示出比标准卡马西平 (PI = 6.45) 更高的安全性。此外,化合物 4i 对戊四唑和 3-巯基丙酸诱导的癫痫发作的效力表明其具有广谱活性,
