| Biological Activity | Ethosuximide是一种广泛使用的抗癫痫药，它能改善多种神经退行性疾病模型的表型，并能阻断低电压激活的 T 型钙通道。[1-4] |
| In Vitro | 抗癫痫药物乙琥胺(ethosuximide)能挽救秀丽隐杆线虫(C. elegans)dnj-14基因无效突变体所表现出的寿命短和化学感觉缺陷；它还能改善表达导致额颞叶痴呆症的人类 Tau 突变体的蠕虫的运动障碍和短寿命；乙琥胺还能增加哺乳动物神经元细胞中经典 FOXO 靶基因的表达并减少蛋白质聚集。[1]Ethosuximide通过抑制特定化学感应神经元而起到延长寿命的作用。[2]ETH能有效诱导体外海马源性NSC增殖和神经元分化。 乙琥胺(ETH)可抑制 Aβ 介导的海马神经原和 Akt/Wnt/β-catenin 通路基因表达。ETH激活了已知参与神经发生调控的PI3K-Akt和Wnt-β-catenin转导通路。抑制PI3K-Akt和Wnt-β-catenin通路可有效阻断ETH的有丝分裂和神经发生效应。硅学分子靶标预测对接研究表明，ETH与Akt、Dkk-1和GSK-3β相互作用。[3] |
| In Vivo | 乙琥胺能促进NSC增殖和神经元分化，减少Aβ毒素介导的毒性和神经变性，从而使大鼠阿尔茨海默病(AD)在内的各种神经退行性得到恢复。[3] |
| Cell Experiment | 在6孔板中培养小鼠神经母细胞瘤细胞系(N2A)，用视黄酸诱导神经分化。24小时后，用PBS或不同浓度ethosuximide处理N2A细胞5小时。提取总RNA，加入DNase并逆转录成cDNA。以此为模板进行qRT-PCR。[1] |
