Substituted piperazine and aniline derivatives of oxazolidin-2,4-diones and imidazolidin-2,4-diones were synthesized by N3 alkylation and screened for their anticonvulsant activity by the maximal electroshock (MES) test, and their neurotoxicity was evaluated by the rotarod test. Among all the synthesized derivatives, compounds 4b, 6c, 6d, 10b, 11a, 11b, and 11d were found to exhibit maximum seizure
通过N 3烷基化合成恶唑烷-2,4-二酮和咪唑烷基-2,4-二酮的取代的哌嗪和苯胺衍生物,并通过最大电击(MES)试验筛选其抗惊厥活性,并通过旋转脚踏仪评估其神经毒性测试。在所有合成衍生物中,发现化合物4b,6c,6d,10b,11a,11b和11d在MES测试中显示出最大的癫痫发作保护作用,并且没有任何神经毒性作用。此外,在体内评估了这些化合物对5-HT 1A的功能活性通过使用大鼠的直肠体温和较低的唇缩回来产生受体亲和力,同时进行小鼠头部抽搐反应以确定对5-HT 2A受体的可能亲和力。这些测试的结果表明,化合物4b,6c,6d,10b,11a,11b和11d具有5-HT 1A(突触前和突触后)激动剂/拮抗剂特征,而化合物11a和11b具有5-HT 2A的拮抗作用。受体。从体内研究发现,大多数苯胺衍生物(发现6c,6d,11a,11b,11d与其活泼的哌嗪同类物(4b,10b)相比更具活性
