General description

β-Naphthoflavone is a polyaromatic hydrocarbon.

Application

β-Naphthoflavone has been used:
  • as aryl hydrocarbon receptor agonist to elucidate its effect on Cyp1A1 expression in embryos of transgenic cytochrome P450 1A1 (cyp1a) reporter zebrafish
  • as AhR agonists, to treat primary normal human epidermal keratinocytes (NHEKs) to study about aryl hydrocarbon receptor (AhR) activation by western blot analysis
  • to determine its effect on the expression of dystrophin (Dp)71
  • to stimulate the expression of causes recombination (Cre) recombinase and to delete the flanking alleles of locus of crossing (x) over, P1 (loxP) sequences

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.
