Alzheimer's disease (AD) is associated with multifactorial neuropathological conditions, which include cholinergic deficit, amyloid-beta plaques formation, loss of neuronal plasticity and neuronal death. Treating such multifactorial conditions with a single target directed approach is considered to be inadequate. Accordingly, multi-target directed ligand (MTDL) strategy has been evolved as an auspicious
阿尔茨海默氏病(AD)与多因素神经病理学状况相关,包括胆碱能缺乏,淀粉样β斑块形成,神经元可塑性丧失和神经元死亡。用单一靶标定向方法治疗这种多因素疾病被认为是不充分的。因此,已经发展了多靶标定向配体(MTDL)策略作为用于治疗AD的吉祥方法。有鉴于此,采用脚手架跳跃式MTDLs策略设计了2-取代的苯并[d]恶唑-5-胺衍生物(29-39; 86-107)库,并通过各种体外和体外方法进行了合成和评估。体内生物学研究。最佳化合物92对AChE(IC50 = 0.052±0.010μM),BuChE(IC50 = 1.085±0.035μM),和显着的淀粉样β聚集(20μM)抑制作用。该化合物在PAMPA分析中具有更好的血脑屏障通透性(Pe = 10.80±0.055×10-6 cm s-1),并在SH-SY5Y神经母细胞瘤细胞系中具有神经保护特性(40μM)。此外,在Y-迷宫测试(东pol碱诱
