disease. Rosmarinic acid, which is one of the main aggregation inhibitors derived from Lamiaceae, was employed as a lead compound and its 25 derivatives were synthesized. In this study, the structure–activity relations of rosmarinic acid derivatives for the amyloid-β aggregation inhibitory effect (MSHTS assay), antioxidant properties, and xanthine oxidase inhibition were evaluated. Among the tested compounds
淀粉样β聚集抑制剂有望成为阿尔茨海默氏病的治疗剂或预防剂。迷迭香酸是衍生自唇形科的主要聚集抑制剂之一,被用作前导化合物,并合成了其25种衍生物。在这项研究中,评价了迷迭香酸衍生物对淀粉样β聚集抑制作用(MSHTS分析),抗氧化剂特性和黄嘌呤氧化酶抑制的构效关系。在测试的化合物中,化合物16d和19被发现是最有效的淀粉样蛋白聚集抑制剂。SAR揭示了在分子的一侧存在酚羟基的必要性以及整个分子的亲脂性。这些结构特性的重要性也受到对接模拟的支持。
