Kushenol A (Leachianone E) 从苦参根中分离出来的。Kushenol A 是一种非竞争性酪氨酸酶 (tyrosinase) 抑制剂，可阻止 L-tyrosinase 转化为 L-DOPA，IC50 和 Ki 值分别为 1.1 μM 和 0.4 μM。Kushenol A 是一种类黄酮抗氧化剂，对 α-葡萄糖苷酶 (alpha-glucosidase) (IC50: 45 μM; Ki: 6.8 μM) 和 β-淀粉酶 (beta-amylase) 具有抑制作用。Kushenol A 被认为是化妆品针对皮肤美白和衰老的潜在酶抑制剂。
| 生物活性 |
Kushenol A (Leachianone E) is isolated from the root of Sophora flavescent. Kushenol A is a non-competitive tyrosinase inhibitor to block the conversion of L-tyrosine to L-DOPA, shows IC50 and Kivalues of 1.1 μM and 0.4 μM, respectively. Kushenol A is a flavonoid antioxidant, has inhibitory effects on alpha-glucosidase (IC50: 45 μM; Ki: 6.8 μM) and β-amylase. Kushenol A is confirmed as potential inhibitors of enzymes targeted by cosmetics for skin whitening and aging. |
