respectively). Since anticonvulsant drugs are often effective in neuropathic pain management, the antinociceptive activity for two the promising compounds—namely, 6 and 19—was also investigated in the formalin model of tonic pain. Additionally, for the aforementioned compounds, the affinity for the voltage-gated sodium and calcium channels, as well as GABAA and TRPV1 receptors, was determined. As a
合成了一系列新的3-(2-氯苯基)-和3-(3-氯苯基)-吡咯烷-2,5-二酮-乙酰胺衍生物作为潜在的抗惊厥药和镇痛药。在以下急性癫痫模型中对获得的化合物进行了评估:最大电击(MES),精神运动(6 Hz,32 mA)和皮下戊四氮(sc PTZ)癫痫发作测试。活性最高的物质-3-(2-氯苯基)-1- 2- [4-(4-氟苯基)哌嗪-1-基] -2-氧代乙基}-吡咯烷-2,5-二酮(6)显示更多有益的ED 50和保护指数值均高于参考药物丙戊酸(在MES测试中分别为68.30 mg / kg与252.44 mg / kg和在6 Hz(32 mA)测试中分别为28.20 mg / kg与130.64 mg / kg)。由于抗惊厥药物通常在神经性疼痛的治疗中有效,因此还在福尔马林的强直性疼痛模型中研究了两种有前途的化合物(即6和19)的抗伤害感受活性。另外,对于上述化合物,测定了对电压门控的钠和钙通道以及GABA
