new inhibitors of AChE combining pyridine, acylhydrazone and N-benzylpiperidine fragments were developed in this work. The hit structure was optimized to yield the compound 21 with an IC50 value of 6.62 nM against AChE, while almost no inhibitory effect against BChE. ADMET predictions and PAMPA permeability evaluation showed good drug-like property. The higher activity with an intermediate alkyl chain
胆碱能耗竭是AD患者中残疾和痴呆的直接原因。AChE是胆碱能疾病的经典和关键靶标。在这项工作中,开发了一些新的结合乙酰吡啶,酰基hydr和N-苄基哌啶片段的AChE抑制剂。优化命中结构以产生具有针对AChE的IC 50值为6.62 nM的化合物21,而几乎对BChE没有抑制作用。ADMET预测和PAMPA渗透性评估显示出良好的类药物性质。具有中间烷基链取代的较高活性表明抑制剂与AChE的新结合方式。这一发现为结合机制提供了新的见解,并有助于发现新型的高活性AChE抑制剂。
