evaluated as dual inhibitors of cholinesterases (ChEs) and self-induced β-amyloid (Aβ) aggregation. All the synthesized compounds had high acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE) inhibitory activity with IC50 values at the nanomolar range, which were much better than tacrine alone. A Lineweaver–Burk plot and molecular modeling study showed that these hybrids targeted both the catalytic
一系列新的他克林-multialkoxybenzene杂种(的图9a - 9N)设计,合成和评价为胆碱酯酶(胆碱酯酶)和自诱导β的双重抑制剂-淀粉样蛋白(Aβ)聚集。所有合成的化合物均具有较高的乙酰胆碱酯酶(AChE)和丁酰胆碱酯酶(BuChE)抑制活性,IC 50值在纳摩尔范围内,比单独使用他克林要好得多。Lineweaver-Burk图和分子建模研究表明,这些杂种同时针对AChE的催化活性位点(CAS)和外围阴离子位点(PAS)。此外,化合物9a – 9f具有亚甲二氧基苯部分的化合物显示出比参考化合物姜黄素更高的自我诱导的Aβ聚集抑制活性。这些化合物可以被选作多效药物,以进一步研究治疗AD。
