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 IC 50 and K i values of 1.1 μM and 0.4 μM, respectively [1] . Kushenol A is a flavonoid antioxidant, has inhibitory effects on alpha-glucosidase ( IC 50 : 45 μM; K i : 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] .
Kushenol A (25 μM) exhibits a highly potent inhibitory activity on ABTS+ radical scavenging with an IC
50
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 IC
50
values of 5.3 μg/ml and 20.5 μg/ml for A549 and NCI‐H226 cells, respectively. It shows an IC
50
value of 57.2 μg/ml for BEAS-2B cells
[3]
.
MCE has not independently confirmed the accuracy of these methods. They are for reference only.
