Chemical Structure
Kushenol A
Synonym(s): Leachianone E
- CAS No.: 99217-63-7
- Formula:C25H28O5
- Molecular Weight:408.49
IUPAC Name: (S)-5,7-dihydroxy-2-(2-hydroxyphenyl)-8-((R)-5-methyl-2-(prop-1-en-2-yl)hex-4-en-1-yl)chroman-4-one
InChIKey: OGBMVWVBHWHRGD-MWTRTKDXSA-N
SMILES: O=C1C[C@@H](C2=CC=CC=C2O)OC3=C(C[C@H](C(C)=C)C/C=C(C)\C)C(O)=CC(O)=C13
Biological Activity: 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].
