agents for the treatment of Alzheimer's disease (AD) (Eur. J. Med. Chem. 2015, 89, 349-361). The results of in vitro biological activity evaluation, including β-amyloid (Aβ) aggregation inhibition, cholinesterase inhibition, and antioxidant activity, showed that introduction of N-methyl in quinoline ring significantly improved the anti-AD potential of compounds. The optimal compound, compound a12, dramatically
根据我们之前对2-芳基乙烯基喹啉类似物作为多功能药物治疗阿尔茨海默氏病(AD)的研究,设计和合成了一系列2-芳基乙烯基-N-甲基喹啉鎓衍生物(Eur.J.Med.Chem.2015,89, 349-361)。体外生物活性评估的结果包括β-淀粉样蛋白(Aβ)聚集抑制,胆碱酯酶抑制和抗氧化活性,表明在喹啉环中引入N-甲基可显着提高化合物的抗AD潜力。最佳化合物a12通过阻止ROS的产生并增加GSH的水平,大大减轻了谷氨酸诱导的HT22细胞的细胞死亡。最重要的是,a12•HAc的胃内给药对高达2000 mg / kg的剂量具有良好的耐受性,并且可以穿越血脑屏障。
