A series of new isoliquiritigenin (ISL) derivatives were synthesized and evaluated as dual inhibitors for amyloid-beta (Aβ) aggregation and 5-lipoxygenase (5-LO). It was found that all these synthetic compounds inhibited Aβ (1–42) aggregation effectively with their IC50 values ranged from 2.2 ± 1.5 μM to 23.8 ± 2.0 μM. These derivatives also showed inhibitory activity to 5-LO with their IC50 values
合成了一系列新的异源寡糖原蛋白(ISL)衍生物,并将其评估为β-淀粉样蛋白(Aβ)聚集和5-脂氧合酶(5-LO)的双重抑制剂。发现所有这些合成化合物均能有效抑制Aβ(1-42)聚集,其IC 50值为2.2±1.5μM至23.8±2.0μM。这些衍生物还显示出对5-LO的抑制活性,其IC 50值范围为6.1±0.1μM至35.9±0.3μM。研究了它们的结构-活性关系(SAR)和抑制机理。这项研究为进一步开发ISL衍生物作为阿尔茨海默氏病(AD)的多功能药物提供了潜在的重要信息。
