5,6-Benzoflavone (beta-Naphthoflavone) is an exogenous ligand for the aryl hydrocarbon receptor, which disrupts zinc homeostasis in human hepatocellular carcinoma HepG2 cells. 5,6-Benzoflavone (beta-Naphthoflavone) possesses anti-inflammatory and antioxidant activities, inhibits LPS-induced inflammation through the AKT/Nrf-2/HO-1-NF-kappaB signaling axis, inhibits TNF-alpha-induced ICAM-1 and VCAM-1 expression, which can be used to study neurodegenerative diseases.
