生物活性

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].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
