A novel series of benzothiazole–piperazine hybrids were rationally designed, synthesized, and evaluated as multifunctional ligands against Alzheimer's disease (AD). The synthesized hybrid molecules illustrated modest to strong inhibition of acetylcholinesterase (AChE) and Aβ1-42 aggregation. Compound 12 emerged as the most potent hybrid molecule exhibiting balanced functions with effective, uncompetitive
一系列新型苯并噻唑-哌嗪杂化物经过合理设计、合成和评估,可作为抗阿尔茨海默病 (AD) 的多功能配体。合成的杂合分子显示了对乙酰胆碱酯酶 (AChE) 和 Aβ 1-42聚集的适度至强烈抑制。化合物12成为最有效的杂合分子,表现出平衡的功能,对 AChE 具有有效、非竞争性和选择性抑制 (IC 50 = 2.31 μM),良好的铜螯合,Aβ 1-42聚集抑制(53.30%)和分解活动。共聚焦激光扫描显微镜和 TEM 分析也验证了该化合物的 Aβ 原纤维抑制能力。此外,该化合物还显示出低毒性,并且能够阻止由 H 2 O 2神经毒性在 SHSY-5Y 细胞中引起的细胞活力丧失。值得注意的是,化合物12显着改善了小鼠模型中东莨菪碱诱导的记忆缺陷的认知和空间记忆。因此,我们的结果证实了新型杂合分子12对 AD的多功能性质,它可能是未来作为有效治疗剂进一步开发的合适线索。
