seizure tests. Further, neurotoxicity evaluation was carried out using rotarod method. Structure activity relationship studies showed that compounds possessing aromatic group at the piperazine ring displayed potent anticonvulsant activity. Majority of the compounds showed anti-MES activity whereas compounds 39, 41, 42, 43, 44, 50, 52, and 53 exhibited anticonvulsant activity in both seizure tests. All the
一系列的烷基/芳基/杂芳基哌嗪衍生物(37 - 54),设计并作为潜在的抗惊厥药合成。目标化合物具有令人满意的物理化学和药代动力学特性。在最大电击(MES)和皮下戊四氮(sc-PTZ)癫痫发作试验中筛选了合成的化合物的体内抗惊厥活性。此外,使用旋转法进行神经毒性评估。结构活性关系研究表明,在哌嗪环上具有芳族基团的化合物显示出有效的抗惊厥活性。化合物多数表现抗MES活性,而化合物39,41,42,43,44,50,52,和53中都发作表现出测试抗惊厥活性。除了所有的化合物42,46,47,和50没有表现出神经毒性。活性最高的衍生物45在MES测试中显示出有效的抗惊厥活性,剂量为30 mg / kg(0.5 h)和100 mg / kg(4 h),并且在sc-PTZ测试中也具有出色的保护作用(100 mg / kg)在两个时间间隔。因此,化合物45在被广泛用于研究癫痫发生模型的PTZ癫痫发作模
