screening of a library (Drug Central Database) containing 4199 FDA-approved drugs was utilized for the purpose, and denopamine, guanethidine, and propamidine were identified as hits to target both acetylcholinesterase (AChE) and β-secretase (BACE-1). Further, MM/GBSA and MD simulation analysis was also performed which suggested that propamidine, an antibacterial and antifungal drug, may become a crucial pharmacophore
多功能药物的使用可以作为治疗阿尔茨海默病 (AD) 等神经退行性疾病的关键策略。为了寻找用于治疗 AD 的多靶点定向配体,已经使用计算机工具进行了药物重新定位研究。为此目的,对包含 4199 种 FDA 批准药物的库(药物中央数据库)进行了虚拟筛选,地诺巴胺、胍乙啶和丙脒被确定为靶向乙酰胆碱酯酶 (AChE) 和 β-分泌酶 (BACE-1) 的目标。此外,还进行了 MM/GBSA 和 MD 模拟分析,表明丙脒是一种抗菌和抗真菌药物,可能成为设计用于 AD 治疗的多靶点定向配体的关键药效团。最后,合成了一系列结构修饰的丙脒衍生物,通过在两端用取代的苯甲酰胺和乙酰胺部分取代末端脒来合成、表征和测试它们的抗 AD 作用。结构修饰的丙脒系列化合物27在亚微摩尔浓度范围内显示出显着的体外hAChE 和 hBACE-1 抑制作用(hAChE:IC 50 = 0.832 ± 0.05 µM 和 hBACE-1:IC
