A series of new purines containing triazole and other heterocycle substituents was synthesized and evaluated for their preliminary anticonvulsant activity and neurotoxicity by using the maximal electroshock (MES), subcutaneous pentylenetetrazole (scPTZ) and rotarod neurotoxicity (TOX) tests. Among the compounds studied, 9-decyl-6-(1H-1,2,4-triazol-1-yl)-9H-purine (5e) was the most potent compound,
合成了一系列含有三唑和其他杂环取代基的新嘌呤,并通过最大电击(MES),皮下戊烯四唑(scPTZ)和轮状神经毒性(TOX)测试评估了它们的初步抗惊厥活性和神经毒性。在所研究的化合物中,9-癸基-6-(1 H -1,2,4-三唑-1-基)-9 H-嘌呤(5e)是最有效的化合物,中位有效剂量为23.4 mg /小鼠腹膜内给药后体重超过25.6千克,并且具有超过25.6的高保护指数。化合物5e对小鼠的MES诱发的癫痫发作表现出显着的口服活性,ED 50为39.4 mg / kg,PI高于31.6。这些结果证明了在MES,scPTZ和TOX模型中,5e具有更好的抗惊厥活性,并且比市售的卡马西平和丙戊酸盐更安全。
