Chemical Structure
Sequoiaflavone
- CAS No.: 21763-71-3
- Formula:C31H20O10
- Molecular Weight:552.48
IUPAC Name: 5,7-dihydroxy-8-(2-hydroxy-5-(5-hydroxy-7-methoxy-4-oxo-4H-chromen-2-yl)phenyl)-2-(4-hydroxyphenyl)-4H-chromen-4-one
InChIKey: TYUMAYSMJLPFAN-UHFFFAOYSA-N
SMILES: O=C1C=C(C2=CC=C(O)C=C2)OC3=C(C4=CC(C5=CC(C6=C(O)C=C(OC)C=C6O5)=O)=CC=C4O)C(O)=CC(O)=C13
Biological Activity: Sequoiaflavone is a biflavonoid compound with multiple activities. Sequoiaflavone suppresses hepatic CYP1A1/(7-Ethoxycoumarin O-deethylase) ECOD, prevents Aβ1-42 fibrillization (IC50 = 0.29 μM) and disaggregates amyloid fibrils (EC50 = 2.04 μM), inhibits Alternaria alternata and inhibits human recombinant PDE5A1 overexpressed in COS-7 cells (IC50 = 19.9 μM) to exert NO-independent vasodilation. Sequoiaflavone can be used in Alzheimer's disease, peripheral circulatory disorder, and antifungal research[1][2][3][4].
