identify compounds with neuronal activity. Starting from two racemic derivatives that were active in cortical neurons, two potent analogues (1b and 2b) were resolved, which were protective against mutant SOD1 induced toxicity in PC-12 cells. Both compounds were found to be active in cortical neurons and presented good ADME profiles in vitro. On the basis of these results, an ALS mouse trial with 1b was carried
环己烷 1,3-二酮被鉴定为一类对 PC-12 细胞中突变 SOD1 诱导的毒性表现出保护作用的分子,但优化的类似物对 G93A SOD1 肌萎缩侧索硬化小鼠模型的寿命延长几乎没有影响或没有影响(ALS)。额外的测试表明这些化合物在神经元中是无活性的,并且进行了进一步的类似物合成以鉴定具有神经元活性的化合物。从在皮质神经元中活跃的两种外消旋衍生物开始,两种有效的类似物(1b和2b) 得到解决,这对 PC-12 细胞中突变 SOD1 诱导的毒性具有保护作用。两种化合物都被发现在皮层神经元中具有活性,并在体外表现出良好的 ADME 特征。在这些结果的基础上,使用1b进行了ALS 小鼠试验,结果显示比 FDA 批准的 ALS 药物利鲁唑的寿命延长略长,从而验证环己烷 1,3-二酮作为治疗 ALS 的新型治疗剂.
