β-Naphthoflavone
Based on 1 publication(s) in Google Scholar
β-Naphthoflavone is an exogenous aryl hydrocarbon receptor (AHR) ligand. β-Naphthoflavone can activate AHR to participate in various biological processes, including cell growth, differentiation, apoptosis, and metabolism. β-Naphthoflavone has antioxidant activity and can exert its antioxidant function by regulating the activity of antioxidant enzymes. β-Naphthoflavone is also a non-carcinogenic CYP1A inducer and can be used to study aristolochic acid (AAI) induced renal injury.

β-Naphthoflavone (0.1, 1 and 10 µM; 3 days) increases CYP1A1 mRNA levels in HepG2 cells in a dose-dependent manner and decreases the level of labile zinc in HepG2 cells by approximately 5%, 10% and 17%, respectively[1]. β-Naphthoflavone (0-50 µM; 24 h) attenuats the decreased viability and increases apoptosis of neuronal SH-SY5Y cells induced by H2O2[2]. β-Naphthoflavone (10 µM) significantly increases the activities of CAT and SOD enzymes in neuronal SH-SY5Y cells and inhibites p38MAPK to attenuate H2O2 induced damage[2].
