Novel donepezil-chalcone-rivastigmine hybrids as potential multifunctional anti-Alzheimer's agents: Design, synthesis, in vitro biological evaluation, in vivo and in silico studies
Given the complex pathogenesis of AD, the multi-target-directed ligands (MTDLs) strategy is considered as the promising therapy. Herein, a series of novel donepezil-chalone-rivastigmine hybrids was rationally designed and synthesized by fusing donepezil, chalone and rivastigmine. The in vitro bioactivity results displayed that compound 10c was a reversible huAChE (IC50 = 0.87 μM) and huBuChE (IC50 = 3
阿尔茨海默病 (AD) 是一种慢性进行性脑神经退行性疾病。到目前为止,还没有有效的药物来阻止或逆转 AD 的进展。鉴于 AD 的复杂发病机制,多靶点定向配体 (MTDLs) 策略被认为是有前途的治疗方法。在此,通过融合多奈哌齐、查龙和卡巴拉汀,合理设计合成了一系列新型多奈哌齐-查龙-卡巴拉汀杂化物。体外生物活性结果显示,化合物10c是可逆的hu AChE (IC 50 = 0.87 μM) 和hu BuChE (IC 50 = 3.3 μM) 抑制剂。它还通过抑制 IL-6 和 TNF-α 的产生而表现出显着的抗炎作用,并显着抑制自身介导的 A β 1-42聚集(60.6%)和hu AChE 介导的 A β 1-40聚集(46.2%)。此外,10c对 A β 1-42诱导的 PC12 细胞损伤和 HT22 细胞中激活的 UPS 通路降解 tau 和淀粉样前体蛋白 (APP) 显示出显着的
Novel indanone-chalcone esters with potential anti-Alzheimer effects designed using hybridization and bioisosteric replacement approaches
Using molecular hybridization and bioisosteric replacement approaches, novelagents with potential use for the treatment of Alzheimer’s disease (AD) were developed based on the structure of donepezil. A series of 14 indanone-chalcones bearing ester group were designed, synthesized, and then characterized using variety of methods. All target compounds showed moderate acetylcholinesterase (AChE) inhibitory
使用分子杂交和生物电子等排替代方法,基于多奈哌齐的结构开发了具有治疗阿尔茨海默病 (AD) 潜力的新型药物。设计、合成了一系列 14 种带有酯基的茚满酮查尔酮,然后使用多种方法对其进行了表征。所有目标化合物均显示出中等的乙酰胆碱酯酶 (AChE) 抑制效力,其中活性最强的化合物8e显示出对 AChE 的 IC 50值为 18.7 µM 的抑制活性。同时,对合成化合物的Aβ1-40聚集抑制活性进行评价,结果表明化合物8h能够抑制Aβ1-40聚集了81.6%。对接研究结果表明,部分化合物与AChE的结合位点吻合良好。最活跃的 AChE 抑制衍生物8e具有与多奈哌齐(参考化合物)接近的物理化学性质,并且相对于参考化合物通过了更多的药物相似性过滤器。总的来说,目前的研究为在开发新的 AD 活性化合物的过程中设计具有酯基的药物大小分子以靶向乙酰胆碱酯酶提供了见解。 图形概要

the results were indicative of a reversible partial noncompetitive type of inhibition. A molecular docking study was conducted to determine the possible allosteric binding mode of 4b with the enzyme. The allosteric nature of AChE inhibition by these compounds provides the opportunity for the design of subtype-selective enzyme inhibitors. The presented indanone–carbamate scaffold can be structurally modified
