Kushenol A  (Synonyms: Leachianone E) 纯度: 99.84%

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[1]. Kushenol A is a flavonoid antioxidant, has inhibitory effects on alpha-glucosidase (IC50: 45 μM; Ki: 6.8 μM) and β-amylase[2]. Kushenol A is confirmed as potential inhibitors of enzymes targeted by cosmetics for skin whitening and aging[1].

IC50 & Target

IC50: 1.1 μM (tyrosinase); 45 μM (alpha-glucosidase)[1][2]
体外研究
(In Vitro)

Kushenol A (25 μM) exhibits a highly potent inhibitory activity on ABTS+ radical scavenging with an IC50 value of 9.7 ± 0.1 μM, and exhibits inhibits scavenging activity as a percentage 93.7% at 25 μM[1].
Kushenol A (0-60 μg/ml; 24 hours) shows considerable cytotoxic effects against NSCLC cells, exhibits IC50 values of 5.3 μg/ml and 20.5 μg/ml for A549 and NCI‐H226 cells, respectively. It shows an IC50 value of 57.2 μg/ml for BEAS-2B cells[3].

Shanghai Jinpan Biotech Co Ltd has not independently confirmed the accuracy of these methods. They are for reference only.
