of carbamate derivatives incorporating multifunctional carrier scaffolds were designed, synthesized, and evaluated as potential therapeutic agents for Alzheimer's disease (AD). We used tacrine to modify the aliphatic substituent, and employed rivastigmine, indole and sibiriline fragments as carrier scaffolds. The majority of compounds exhibited good inhibitory activity for cholinesterase. Notably, compound
在这项研究中,设计、合成了一系列结合多功能载体支架的氨基甲酸酯衍生物,并评估其作为阿尔茨海默病(AD)的潜在治疗剂。我们使用他克林修饰脂肪族取代基,并使用卡巴拉汀、吲哚和西伯林片段作为载体支架。大多数化合物对胆碱酯酶表现出良好的抑制活性。值得注意的是,带有 sibiriline 片段的化合物C7对人乙酰胆碱酯酶 ( h AChE,IC 50 = 30.35 ± 2.07 nM) 和人丁酰胆碱酯酶 ( h BuChE,IC 50 = 48.03 ± 6.41 nM)表现出有效的抑制活性,且神经毒性最小。进一步的研究表明,C7表现出显着的保护PC12细胞免受H 2 O 2诱导的细胞凋亡的能力,并有效抑制活性氧(ROS)的产生。此外,在脂多糖(LPS)诱导的 BV2 细胞炎症模型中, C7有效减弱促炎细胞因子的水平。透析12小时后, C7继续表现出对胆碱酯酶活性的抑制作用。体内急性毒性测试表明,与母核他克林相比,
