Cytosporone B is a natural fungal metabolite primarily studied for its potential therapeutic applications in medicine, particularly in cancer research. It acts as an activator of the nuclear receptor Nur77, inducing apoptosis (programmed cell death) in cancer cells, making it a candidate for anti-cancer drugs targeting treatment-resistant tumors. It also modulates cellular pathways involved in inflammation and immune response, with potential for treating inflammatory diseases and autoimmune disorders. Additionally, its antioxidant properties may benefit conditions involving chronic inflammation or cellular degeneration.

In agriculture, Cytosporone B shows promise as a plant growth regulator or fungicide, inhibiting the growth of certain plant-pathogenic fungi. This could reduce reliance on synthetic pesticides and promote sustainable farming practices. Research continues to evaluate its efficacy and safety across these applications.
