描述 |
Ladostigil (TV-3326) 是胆碱酯酶 (cholinesterase) 和脑选择性单胺氧化酶 (MAO) 的双重抑制剂,抑制 MAO-B 和 AChE 的 IC50 值分别为 37.1 和 31.8 μM。Ladostigil 能够增加胆碱能的传递,防止 ROS 的形成或其作用,可用于抑郁症和阿尔茨海默氏病的研究。

体外研究 |
Ladostigil(1-10µM)具有神经保护作用,包括防止线粒体膜电位(ψ)下降、减少凋亡级联和抑制OS损伤诱导的ROS生成[2]。Ladostigil(1-10µM)具有显著的神经保护活性,包括抑制caspase-3激活,诱导Bcl-2,减少Bad和Bax基因及蛋白在人神经母细胞瘤SK-N-SH细胞中的表达[2]。

体内研究 |
Ladostigil(17 mg/kg;每天一次,持续6周)可以消除从青春期到出生前应激大鼠在高架迷宫(EPM)和强迫游泳试验(FST)中的过度紧张和抑郁样行为[4]。拉多西地尔(50μmol/kg;单次给药)可恢复大鼠在物体识别实验中的情景记忆丧失[3]。动物模型:无病原体(SPF)Sprague-Dawley大鼠[4]剂量:17mg/kg给药:P.o.(添加到饮用水中)连续6周。结果:脑MAO-A和MAO-B抑制率超过60%。EPM中雄性和雌性产前应激(PS)大鼠的过度紧张和FST中抑郁样行为的降低。
