We developed a focused set of original hybrid pyrrolidine-2,5-dione derivatives with potent anticonvulsant and antinociceptive properties. These hybrid compounds demonstrated broad-spectrum protective activity in a range of mouse models, such as the maximal electroshock (MES) test, the pentylenetetrazole-induced seizures (scPTZ), and the 6 Hz (32 mA) seizures. Compound 22 showed the most potent anticonvulsant activity (ED50 MES = 23.7 mg/kg, ED50 6 Hz (32 mA) = 22.4 mg/kg, ED50scPTZ = 59.4 mg/kg). In addition, 22 revealed potent efficacy in the formalin-induced tonic pain. These in vivo activities of 22 are likely mediated by several targets and may result from the inhibition of central sodium/calcium currents and transient receptor potential vanilloid 1 (TRPV1) receptor antagonism. Finally, the lead compound 22 revealed drug-like absorption, distribution, metabolism, excretion, toxicity (ADME-Tox) properties in the in vitro assays, making it a potential candidate for further development in epilepsy and neuropathic pain indications.

衍生自(2,5-二氧杂吡咯烷-1-基)(苯基)-乙酰胺的多靶点化合物,作为有效的抗惊厥药和抗伤害感受药的候选人。
我们开发了一组重点集中的原始杂种吡咯烷-2,5-二酮衍生物,具有强大的抗惊厥和抗伤害感受特性。这些杂合化合物在一系列小鼠模型中表现出广谱的保护活性,例如最大电击(MES)测试,戊烯四唑诱导的癫痫发作(sc PTZ)和6 Hz(32 mA)癫痫发作。化合物22显示出最有效的抗惊厥活性(ED 50 MES = 23.7 mg / kg,ED 50 6 Hz(32 mA)= 22.4 mg / kg,ED 50 sc PTZ = 59.4 mg / kg)。此外,有22种药物在福尔马林引起的强直性疼痛中显示出强效功效。这些体内活性的22可能是由几个靶标介导的,并且可能是由于抑制中央钠/钙电流和瞬时受体电位香草酸1(TRPV1)受体拮抗作用所致。最后,先导化合物22在体外测定中显示出类药物的吸收,分布,代谢,排泄,毒性(ADME-Tox)特性,使其成为癫痫和神经性疼痛指征进一步发展的潜在候选者。
