A series of novel phthalimide-alkylamine derivatives were synthesized and evaluated as multi-functions inhibitors for the treatment of Alzheimer’s disease (AD). The results showed that compound TM-9 could be regarded as a balanced multi-targets active molecule. It exhibited potent and balanced inhibitory activities against ChE and MAO-B (huAChE, huBuChE, and huMAO-B with IC50 values of 1.2 μM, 3.8 μM
合成了一系列新型邻苯二甲酰亚胺-烷基胺衍生物,并将其作为多功能抑制剂用于治疗阿尔茨海默氏病(AD)。结果表明,化合物TM - 9可以作为平衡的多靶标活性分子。它显示出对ChE和MAO-B(hu AChE,hu BuChE和hu MAO-B的有效且平衡的抑制活性,IC 50值分别为1.2μM,3.8μM和2.6μM)且选择性低。对AChE抑制的动力学分析和分子建模研究均表明TM - 9同时与AChE的催化活性位点和外围阴离子位点结合。有趣的是,化合物TM - 9遵循Lipinski的5条规则。此外,我们的研究证明TM - 9具有弱的细胞毒性,并且可以在体外穿过血脑屏障(BBB)。结果表明,化合物TM - 9是一种有趣的多目标活性分子,为针对阿尔茨海默氏病的药物发现过程中进一步的铅优化提供了有吸引力的起点。
