that the hybrid compounds possessed pronounced antioxidant activity and could effectively protect PC12 cells from the H2O2/Aβ42-induced toxicity. Moreover, the hybrid compounds also showed positive metal ions-chelating ability in vitro, suggesting a potential to halt ion-induced Aβ aggregation. All the obtained results demonstrated that the tacrine-curcumin hybrid compounds, in particular compound K3-2
设计和合成了总共十六种他克林-姜黄素杂合化合物,以寻找多功能抗阿尔茨海默病药物。体外研究表明,这些杂合化合物显示出良好的胆碱酯酶抑制活性。特别地,K3-2的效力甚至超过他克林。由于结构差异,某些化合物对乙酰胆碱酯酶或丁酰胆碱酯酶表现出不同的选择性。因此,基于分子建模研究总结并进一步讨论了结构和活性之间的关系。ORAC和MTT分析表明该杂合化合物具有明显的抗氧化活性,可以有效保护PC12细胞免受H2O2 /Aβ42诱导的毒性作用。此外,杂化化合物在体外也显示出正的金属离子螯合能力,提示有可能阻止离子诱导的Aβ聚集。所有获得的结果证明他克林-姜黄素杂合化合物,特别是化合物K3-2,可以被认为是阿尔茨海默氏病的潜在治疗剂。
