R-substituent was varied, including C(2) stereochemistry, and the compounds were tested in rodent models of seizures and neuropathic pain. C(2)-Hydrocarbon N-benzylamide PAADs were potent anticonvulsants and excellent anticonvulsant activity (mice, ip; rat, po) was observed for C(2) R-substituted PAADs in which the R group was ethyl, isopropyl, or tert-butyl, and the C(2) stereochemistry conformed to the
药理管理仍然是治疗癫痫和神经性疼痛的主要方法。我们已经开发了一种称为功能化氨基酸(FAA)的新型抗惊厥药。在这项研究中,我们研究了从末端乙酰基部分被除去的FAA衍生物,并将其称为这些化合物伯氨基酸衍生物(PAAD)。编写了27个PAAD。中央C(2)R取代基是多样的,包括C(2)立体化学,和化合物在癫痫发作和神经性疼痛的啮齿动物模型中进行了测试。C(2) -烃Ñ -苄基酰胺PAADs是有效的抗惊厥药和优异的抗惊厥活性(小鼠,腹膜内;大鼠,口服)观察到C(2)R-取代PAADs其中R基团是乙基,异丙基,或叔-丁基和C(2)立体化学符合d-氨基酸构型((R)-立体异构体)。这些值超过了几种临床抗癫痫药的活性。C(2)(R)-乙基和C(2)(R)-异丙基PAADs在小鼠(ip)福尔马林神经性疼痛模型中也显示出出色的活性。值得注意的是,与FAA结构-活性关系不同,PAAD抗惊厥活性在亚甲基单元取代
