    • Bio Activity:

      High affinity Nur77 agonist Tocris Bioscience 5459
      Naturally occurring Nur77 (NR4A1) agonist (Kd = 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 gr owth. Also exhibits a potent antifibrotic effect in bleomycin-induced skin fibrosis in vivo.
