intraperitoneal injection in KunMing mice. Among the synthesized compounds 3a-v, 7-(hexyloxy)-2H-benzo[b][1,4]thiazin-3(4H)-one (3f) could be considered potentially the most useful and safe therapeutic compound. Among the synthesized compounds 4a-u, compound 7-(2-fluorobenzyloxy)-4H-[1,2,4]triazolo[4,3-d]benzo[b][1,4]thiazine (4k) was the most active compound with an ED(50) of 17.0 mg/kg, TD(50) of 243.9 mg/kg
一系列7-烷氧基-2H-1,4-苯并噻嗪-3(4H)-和一系列新的7-烷氧基-4H- [1,2,4]三唑并[4,3-d]苯并[b]以5-甲氧基苯并[d]噻唑-2-胺为起始原料合成] [1,4]噻嗪衍生物。化合物的结构通过IR,(1)H-NMR光谱数据和显微分析来阐明。在昆明小鼠腹膜内注射后,通过最大电休克(MES)测试和旋转法测试这些化合物的抗惊厥活性。在合成的化合物3a-v中,7-(己氧基)-2H-苯并[b] [1,4]噻嗪-3(4H)-1(3f)可能被认为是最有用和最安全的治疗化合物。在合成的化合物4a-u中,化合物7-(2-氟苄氧基)-4H- [1,2,4]三唑并[4,3-d]苯并[b] [1,4]噻嗪(4k)最多ED(50)为17.0 mg / kg,TD(50)为243的活性化合物。9 mg / kg,保护指数(PI)为14.3。它的神经毒性低于所有其他合成化合物,也显着低于参考药物卡马西平。
