5-dioxopyrrolidin-1-yl)butanamide derivatives as potential new hybrid anticonvulsant agents was synthesized. These hybrid molecules were obtained as close analogs of previously described N-benzyl derivatives and fuse the chemical fragments of clinically relevant antiepileptic drugs such as ethosuximide, levetiracetam, and lacosamide. The initial anticonvulsant screening was performed in mice (ip) using the ‘classical’
重点研究了21种新的N-苯基-2-(2,5-二氧杂吡咯烷-1-基)丙酰胺,2-(3-甲基-2,5-二氧杂吡咯烷-1-基)丙酰胺和2-(2,合成了5-二氧杂吡咯烷-1-基)丁酰胺衍生物作为潜在的新型杂化抗惊厥药。这些杂合分子是作为先前描述的N-苄基衍生物的紧密类似物获得的,并且融合了临床上相关的抗癫痫药如乙巯丁二酰亚胺,左乙拉西坦和拉考酰胺的化学片段。最初的抗惊厥筛选是在小鼠(ip)上使用“经典”最大电休克(MES)和皮下戊四氮(scPTZ)测试,以及药物耐受性边缘癫痫发作的六赫兹(6 Hz)模型。应用旋转脚架试验,确定了急性神经毒性。在小鼠中(跨越临床前惊厥模型活动的宽光谱的ip)显示的化合物4,5,11,和19。最有利的抗惊厥特性显示4(ED 50 MES = 96.9 mg / kg,ED 50 sc PTZ = 75.4 mg / kg,ED 50 6 Hz = 44.3 mg / kg), 在旋转试验中显示TD
