Description: High affinity Nur77 agonist
Chemical Name: Ethyl 3,5-dihydroxy-2-(1-oxooctyl)-benzeneacetate
Purity: ≥98% (HPLC)
Biological Activity for Cytosporone B
Cytosporone B is a 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 growth. Also exhibits a potent antifibrotic effect in bleomycin-induced skin fibrosis in vivo.

MAPK Signaling Scientific Review
MAP kinase signaling is integral to the regulation of numerous cellular processes such as proliferation and differentiation, and as a result is an important focus of cancer and immunology research. Updated for 2016, this review discusses the regulation of the MAPK pathway and properties of MAPK cascades. Compounds available from Tocris are listed.
Pathways for Cytosporone B
MAPK Signaling Pathway
The mitogen-activated protein kinase pathway evokes an intracellular signaling cascade in response to extracellular stimuli such as heat and stress. It can influence cell division, metabolism and survival.
