A novel series of tacrine derivatives were designed and synthesized by combining caffeic acid (CA), ferulic acid (FA) and lipoic acid (LA) with tacrine. The antioxidant study revealed that all the hybrids have much more antioxidant capacities compared to CA. Among these compounds, 1b possessed a good ability to inhibit the β-amyloid protein (Aβ) self-aggregation, sub-micromole acetylcholinesterase
通过将咖啡酸(CA),阿魏酸(FA)和硫辛酸(LA)与他克林相结合,设计并合成了一系列新的他克林衍生物。抗氧化剂研究表明,与CA相比,所有杂种均具有更大的抗氧化剂能力。在这些化合物中,1b具有良好的抑制β淀粉样蛋白(Aβ)自聚集,亚微摩尔乙酰胆碱酯酶(AChE)/丁酰胆碱酯酶(BuChE)抑制,适度BACE1抑制的能力。此外,化合物1b还是DPPH自由基清除剂和铜螯合剂,并且对谷氨酸诱导的细胞死亡具有有效的神经保护作用,对HT22细胞毒性低。我们的发现表明化合物1b 可能是有前途的多靶点配体,值得进一步开发用于治疗阿尔茨海默氏病。
