of 7-benzylamino-2H-1,4-benzoxazin-3(4H)-ones were synthesized using 2-amino-5-nitrophenol as a starting material. Their anticonvulsant activities were evaluated by the maximal electroshock test (MES test) and their neurotoxicity was evaluated by the rotarod neurotoxicity test (Tox.). The MES test showed that 7-(4-fluorobenzylamino)-2H-1,4-benzoxazin-3(4H)-one 4b was the most potent with ED(50) value
以2-氨基-5-硝基苯酚为起始原料合成了一系列的7-苄基氨基-2H-1,4-苯并恶嗪-3(4H)-。通过最大电击试验(MES试验)评估其抗惊厥活性,并通过旋转脚架神经毒性测试(Tox。)评估其神经毒性。MES测试显示7-(4-氟苄氨基)-2H-1,4-苯并恶嗪-3(4H)-一4b最有效,ED(50)值为31.7 mg / kg,保护指数为(PI = TD (50)/ ED(50))值为7.2。为了解释抗惊厥活性的可能机理,在sc-PTZ试验,异烟肼试验和士丁宁试验中测试了化合物4b。
