The Uses of 5,6-Benzoflavone

beta-Naphthoflavone is a Cytochrome P450 enzyme system inducer. It can also be used in biological study of novel dual-color luciferase reporter assay for simultaneous detection of estrogen and aryl hydrocarbon receptor activation.

What are the applications of Application

β-Naphthoflavone is a Cytochrome P450 enzyme system inducer

Definition

ChEBI: An extended flavonoid resulting from the formal fusion of a benzene ring with the f side of flavone.

General Description

β-Naphthoflavone is a polyaromatic hydrocarbon.

Biochem/physiol Actions

β-Naphthoflavone (BNF) is an exogenous ligand for aryl hydrocarbon receptor (AhR) in humans. It is an inducer of phase I detoxification enzymes (CYPs) and phase II enzymes (UDP-GTs) and NAD(P)H-dependent quinone oxyreductase-1(NQO1). It also induces cytochrome P450 (Cyp1a). BNF represses the expression of Duchenne muscular dystrophy gene, dystrophin (Dp)71 by altering the binding of the transcription factors.
