Abstract A series of novel quinolinone derivatives bearing dithiocarbamate moiety were designed and synthesised as multifunctional AChE inhibitors for the treatment of AD. Most of these compounds exhibited strong and clearly selective inhibition to eeAChE. Among them, compound 4c was identified as the most potent inhibitor to both eeAChE and hAChE (IC50 = 0.22 μM for eeAChE; IC50 = 0.16 μM for hAChE)
抽象的 设计并合成了一系列带有二硫代氨基甲酸酯部分的新型喹啉酮衍生物,作为用于治疗AD的多功能AChE抑制剂。这些化合物中的大多数对ee AChE表现出强烈而明显的选择性抑制。其中,化合物4c中被确定为最有效的抑制剂既EE乙酰胆碱酯酶和ħ胆碱酯酶(IC 50 = 0.22μM为eeAChE; IC 50 = 0.16μM为ħ乙酰胆碱酯酶),它也是对乙酰胆碱酯酶诱导的Aβ的最佳抑制剂聚集(在100μM时为29.02%)和有效的自诱导Aβ聚集抑制剂(在25μM时为30.67%)。动力学和分子建模研究表明,化合物4c是一种混合型抑制剂,可以同时与AChE的催化阴离子位点(CAS)和外围阴离子位点(PAS)相互作用。此外,4c具有良好的穿过BBB的能力,对SH-SY5Y神经母细胞瘤细胞无毒性,并且在高达2500 mg / kg(po)的剂量下对小鼠具有良好的耐受性。
