anti-Alzheimer's agents Naphthalene-triazolopyrimidine hybrids were synthesized and screened in vitro against the two cholinesterases (ChE)s, amyloid β aggregation and for antioxidation activity. Single-crystal X-ray crystallography was utilized for crystal structure determination of one of the compounds. In vitro study of compounds revealed that most of the compounds are capable of inhibiting acetylcholinesterase
为了构建潜在的抗阿尔茨海默氏病药物,合成了萘-三唑并嘧啶杂合物,并针对两种胆碱酯酶(ChE),淀粉样β聚集和抗氧化活性进行了体外筛选。单晶X射线晶体学用于确定一种化合物的晶体结构。化合物的体外研究表明,大多数化合物都能抑制乙酰胆碱酯酶和丁酰胆碱酯酶的活性。尤其是,化合物4e和4d对AChE的IC50值比标准药物多奈哌齐(IC50 49 nM)低,为8.6至14 nM。化合物4e的最佳结果为IC50为8.6 nM(对于AChE)和150 nM(对于BuChE)。在4a,4c和4h观察到高达多奈哌齐的选择性,甚至更高。通过电子显微镜检查 透射电子显微镜和ThT荧光测定揭示了这样的事实,即合成的杂种表现出淀粉样β自聚集抑制作用。化合物4i和4j在50μM时显示出最高的抑制潜力,分别为85.46%和72.77%。高于标准Aβ崩解剂姜黄素。还分析了它们的抗氧化特性。DPPH自由基清除测定法和ORAC
