arylhydrazone moiety were potent antioxidants. All compounds possessed low cytotoxicity and low acute toxicity. Overall, a new promising type of bifunctional CES inhibitors has been found that are able to interact with the active site of the enzyme with the participation of two functional groups. The results indicate that HOPs have the potential to be good candidates as human CES inhibitors for biomedicinal
通过Cu(OAc) 2催化的偶氮偶联获得了一系列扩展的烷基2-芳基肼基-3-氧代-3-多氟烷基丙酸酯(HOPs) 3。所有都是纳摩尔的羧酸酯酶 (CES) 抑制剂,而乙酰胆碱酯酶和丁酰胆碱酯酶的中度或弱抑制剂。稳态动力学研究表明 HOPs 3是三种酯酶的混合型抑制剂。分子对接研究表明,HOP 结构中的两个官能团,三氟甲基酮 (TFK) 和酯基团与 CES 活性位点结合,表明随后的反应:形成四面体加合物和缓慢的水解反应。分子建模的结果使我们能够解释 HOP 3抑制 CES 的一些构效关系:与胆碱酯酶相比,它们对 CES 的选择性和五氟乙基取代的 HOP 3p的高选择性hCES1 与 hCES2 相比。预计所有化合物都具有良好的肠道吸收和血脑屏障渗透性、低心脏毒性、良好的亲脂性和水溶性以及合理的整体药物相似性。在芳基腙部分具有 TFK 基团和电子给体取代基的 HOP 是有效的抗氧化剂。所有化合
