Biological Activity for Cytosporone B

Cytosporone B is a naturally occurring Nur77 (NR4A1) agonist (K_d = 8.52 x 10^-7 M). Induces apoptosis in gastric cancer cells in vitro. Increases blood glucose levels in fasting C57 mice and suppresses xenograft tumor growth. Also exhibits a potent antifibrotic effect in bleomycin-induced skin fibrosis in vivo.
