Biological Activity: Usnic acid is a secondary metabolite of lichens with a unique dibenzofuran skeleton. Usnic acid inhibits DNA/RNA synthesis and has antibacterial activity. Usnic acid induces cell cycle arrest and apoptosis and has anticancer activity. Usnic acid inhibits RANKL-mediated osteoclast formation and function by reducing the transcriptional and translational expression of NFATc1. Usnic acid has antioxidant and anti-inflammatory activities by inhibiting lipid peroxidation and myeloperoxidase[1][2][3][4].
