saccharin derivatives linked by different alicyclic fragments (piperazine, hexahydropyrimidine, 3-aminopyrrolidine or 3-aminopiperidine) with phenylalkyl moieties attached have been designed, synthesized, and evaluated as multifunctional anti-AD agents with cholinesterase, β-secretase and β-amyloid inhibitory activities. In vitro studies showed that the majority of saccharin derivatives with piperazine
阿尔茨海默氏病(AD)的复杂性要求寻找多功能化合物作为有效疗法的潜在候选者。已设计,合成了一系列邻苯二甲酰亚胺和糖精衍生物,它们通过不同的脂环族片段(哌嗪,六氢嘧啶,3-氨基吡咯烷或3-氨基哌啶)连接并连接有苯基烷基部分,并被评估为具有胆碱酯酶,β-分泌酶和β淀粉样蛋白的抑制活性。体外研究表明,具有Ee AChE IC 50的大多数具有哌嗪部分的糖精衍生物和一种具有3-氨基哌啶片段的邻苯二甲酰亚胺衍生物均表现出对乙酰胆碱酯酶(AChE)的抑制作用。值范围从0.83μM到19.18μM。目标化合物在50μM浓度下显示出对人β-分泌酶-1(h BACE1)的抑制作用,范围从26.71%到61.42%。在这些化合物中,二官能剂(26,[2-(2-(4-苄基哌嗪-1-基)乙基)苯并[ d ]异噻唑-3(2 ħ) -酮1,1-二氧化物]和52,2已经确定了-(2-(3-(3,5-二氟苄基氨基)哌啶-1-基)乙基)异吲哚啉-1
