A new aurone, named (Z)-4,5-methylenedioxy-6-hydroxybenzene-2[(2′,3′,4′-trimethoxy)-2-methyl-2(4-methyl-3-penten-1-yl)-2H-1-benzopyran-5-yl)methylene]-3-benzofuranon (1), and nine known aurones (2–10) were isolated from Sophora japonica L. for the first time. Compounds 1–10 were evaluated for their neuroprotective activities against 6-OHDA-induced cell death in SH-SY5Y cells. Compounds 1, 3, 8, and 10 exhibited significant neuroprotective activities with IC50 values in the range of 2.89–6.02 μM.
从日本槐(Sophora japonica L.)中首次分离出一种新的黄酮,命名为(Z)-4,5-亚甲基双氧-6-羟基苯-2[(2′,3′,4′-三甲氧基)-2-甲基-2(4-甲基-3-戊二烯-1-基)-2H-1-苯并呋喃-5-基)亚甲基]-3-苯并呋喃酮(1),以及九种已知黄酮(2–10)。对化合物1–10进行了评估,以测试其对6-OHDA诱导的SH-SY5Y细胞死亡的神经保护活性。化合物1、3、8和10表现出显著的神经保护活性,其IC50值在2.89–6.02 μM范围内。
