of Alzheimer's disease (AD) through pharmacophores-merged approaches based on lead compounds 18d, benzyloxy phenyl analogs, and deferiprone (DFP). These hybrids possessed potent Monoamine oxidase B (MAO-B) inhibition as well as excellent iron chelation, with pFe3+ values ranging from 18.13 to 19.39. Among all the compounds, 8g exhibited the most potent selective MAO-B inhibitor (IC50 = 68.4 nM, SI
摘要 通过基于先导化合物18d、苄氧基苯基类似物和去铁酮的药效团合并方法,创新地设计、合成和生物学评估了一类新的苯甲酰胺-羟基吡啶酮 (HPO) 衍生物作为治疗阿尔茨海默病 (AD) 的潜在多靶点候选药物(DFP)。这些杂种具有有效的单胺氧化酶 B (MAO-B) 抑制作用以及出色的铁螯合性,pFe 3+值范围为 18.13 至 19.39。在所有化合物中,8g表现出最有效的选择性 MAO-B 抑制剂(IC 50 = 68.4 nM,SI = 213)。此外,8g显示出良好的药代动力学特性,并具有巨大的穿透 BBB 的潜力计算机和 PAMPA-BBB 测定。分子模型表明,8g可以采用扩展构象,并且与 MAO-B 的相互作用比18d更强。体外和体内试验表明,8g显着抵抗 Aβ 诱导的氧化并改善东莨菪碱诱导的认知障碍。综上所述,这些结果表明化合物8g是一种潜在的多功能抗 AD 治疗候选药物。
