high-resolution mass spectrometry, which confirm that they can effectively interact with copper(II), iron(II) and zinc(II). The ThT fluorescence binding assay indicates that the synthetic compounds can inhibit Cu(II)-induced Aβ1–42 aggregation. The parallel artificial membrane permeation assay shows that most target compounds can cross the BBB. Based on these results, compound 8a was selected as a potential
设计,合成和评估了一系列具有单胺氧化酶抑制作用和生物金属螯合活性的化合物,作为对抗阿尔茨海默氏病的药物。体外测定表明,大多数目标化合物均表现出良好的MAO-B活性,其亚微摩尔IC 50值和抗氧化活性(1.49-5.67 ORAC-FL值)。选定的化合物用于通过紫外可见光谱和高分辨率质谱测定生物金属的螯合能力,这证实了它们可以与铜(II),铁(II)和锌(II)有效相互作用。ThT荧光结合试验表明合成化合物可抑制Cu(II)诱导的Aβ1–42聚合。平行的人工膜渗透试验表明,大多数目标化合物都可以穿过血脑屏障。根据这些结果,选择化合物8a作为潜在的多功能药物来治疗AD。
