Valproic acid (VPA, 1) is a major broad spectrum antiepileptic and central nervous system drug widely used to treat epilepsy, bipolar disorder, and migraine. VPA’s clinical use is limited by two severe and life-threatening side effects, teratogenicity and hepatotoxicity. A number of VPA analogues and their amide, N-methylamide and urea derivatives, were synthesized and evaluated in animal models of
丙戊酸(VPA,1)是主要的广谱抗癫痫药和中枢神经系统药物,广泛用于治疗癫痫,双相情感障碍和偏头痛。VPA的临床使用受到两种严重且危及生命的副作用,致畸性和肝毒性的限制。合成了许多VPA类似物及其酰胺,N-甲基酰胺和尿素衍生物,并在神经性疼痛和癫痫的动物模型中进行了评估。其中,两种酰胺和两种尿素衍生物(1)作为抗神经痛药的效价最高,酰胺(19和20)的ED 50值分别为49和51 mg / kg,尿素衍生物的ED 50值为49和74 mg / kg。 (29和33)。19,20,和29是等效于加巴喷丁,用于治疗神经性疼痛的主要药物。这些数据表明上述新型化合物作为用于治疗神经性疼痛的未来药物开发的候选物的巨大潜力。
