常見問(wèn)題列表

生物活性
Cytosporone B是天然存在的核孤兒受體Nur77(NR4A1) 激動(dòng)劑,EC50為0.278 nM。
靶點(diǎn)
TargetValue
Nur77
(Cell-free assay)
0.278 nM(EC50)
體外研究

Cytosporone B targets the ligand binding domain of Nur77, which selectively stimulates the transactivational activity of Nur77. Cytosporone B induces luciferase activity in cells that are cotransfected with GAL4- Nur77 or GAL4-LBD. The EC 50 of cytosporone B for Nur77 is 0.278 nM. Cytosporone B displays robust pro-apoptotic activity in gastric cancer cells BGC-823. 63.5% of the cells are apoptotic when treated with cytosporone B for 48 h. Cytosporone B shows selective effect on cancerous cells. Cytosporone B inhibits proliferation of human gastric cancer BGC-823 cells and human colon cancer SW620 cells by 470%, but it has a modest effect on human lung cancer H1299 cells and human hepatoma HepG2 cells.

體內(nèi)研究

In the hepatocytes of wild-type mice, the transcriptional activity of the reporter is induced five-fold with cytosporone B treatment. In wild-type mice, cytosporone B treatment significantly increases glucose levels from 3.2 to 11.4 mM within the first 30 min, and thereafter blood glucose gradually decreased before reaching the initial level after 300 min.
