A series of 4‐(substituted‐phenyl)‐[1,2,4]triazolo[4,3‐a]quinazolin‐5(4H)‐ones (6a–x) with triazole and other heterocyclic substituents (7–14) were synthesized and the compounds were evaluated for their anticonvulsant activity and neurotoxicity by maximal electroshock (MES) and rotarod neurotoxicity tests. Among the compounds studied, 6o and 6q showed wide margins of safety with protective indices
一系列具有三唑和其他杂环取代基 (7-14) 的 4-(取代-苯基)-[1,2,4] 三唑并 [4,3-a] 喹唑啉-5(4H)-酮 (6a-x)合成了化合物,并通过最大电休克 (MES) 和旋转棒神经毒性试验评估了化合物的抗惊厥活性和神经毒性。在研究的化合物中,6o 和 6q 显示出广泛的安全范围,其保护指数 (PI) 远高于目前使用的药物(PI6o > 25.5,PI6q > 26.0)。化合物 6o 和 6q 对 MES 诱导的小鼠癫痫发作显示出显着的口服活性,ED50 值分别为 88.02 和 94.6 mg/kg。还发现这两种化合物对由戊四唑和荷包牡丹碱诱发的癫痫发作具有强效活性。
