three new phenylethanoid glycosides (4–6), and six known compounds (7–12) were isolated from the fruits of Forsythia suspensa. Their structures were determined by comprehensive spectroscopic data and comparison to the literature data. All isolated compounds were evaluated their neuroprotective and anti-inflammatory activities. Compounds 1 and 10 exhibited significant neuroprotective activities with
近年来,神经炎症正在成为主要神经退行性疾病的重要原因。越来越多的证据支持来自中药的生物活性天然产物对神经炎症有效。连翘是一种典型的药材,在之前的药理研究中显示出潜在的神经保护和抗炎特性。在我们的研究,以获得的神经保护和抗发炎的天然产物,三前所未有C6-C7'/ C6-C16'连接的苯乙醇 苷二聚体(1 - 3),三个新的苯乙醇 苷(4 - 6),和六个已知化合物(7 – 12) 是从连翘的果实中分离出来的。它们的结构是通过综合光谱数据和与文献数据的比较来确定的。评估了所有分离的化合物的神经保护和抗炎活性。对于血清剥夺和鱼藤酮诱导的嗜铬细胞瘤 (PC12) 细胞损伤,化合物1和10表现出显着的神经保护活性,细胞活力值分别为 75.24 ± 8.05% 和 93.65 ± 10.17%。同时,化合物1对LPS 诱导的 RAW264.7 细胞中的肿瘤坏死因子 (TNF) -α表达表现出优异的抗炎活性,IC
