Bay 11-7085
Bay 11-7085 (CAS 196309-76-9) is a soluble inhibitor of nuclear factor-kappa B (NF-κB) activation. It inhibits cell proliferation and promotes apoptosis in various cell types through interference with NF-κB signaling pathways. Studies have demonstrated that Bay 11-7085 decreases DNA synthesis in endometriotic stromal cells (ECSCs), leading to cell cycle arrest at G0/G1 phase. Furthermore, treatment with Bay 11-7085 induces apoptosis by downregulating anti-apoptotic proteins such as Bcl-2 and Bcl-XL, while enhancing activation of caspase-3, caspase-8, and caspase-9. Bay 11-7085 is commonly employed as a chemical probe in biomedical research on inflammation and apoptosis pathways.

Reacting condition |
0.01 ~ 10 μM; |
|
Applications |
In ECSCs and NESCs, BAY 11-7085 significantly inhibited cell viability in a dose-dependent manner. At the dose of 10 μM, ECSCs and NESCs treated with BAY 11-7085 showed 66.1% and 54.7% decreases in cell viability, respectively. In addition, according to the results of the BrdU incorporation assay, at the dose of 10 μM, BAY 11-7085 significantly inhibited the BrdU incorporation of ECSCs in a dose-dependent manner (53.2% decrease), whereas BAY 11-7085 only showed a weak inhibitory effect on the BrdU incorporation of NESCs (38.2% decrease). Therefore, BAY 11-7085 showed stronger inhibitory effects on the cell viability and the cell proliferation of ECSCs than on those of NESCs. |

|
Applications |
In rat model of pneumococcal meningitis, BAY 11-7085 significantly reduced meningitis-associated loss of cerebrovascular autoregulation. Besides, also BAY 11-7085 also significantly reduced increases in CSF WBCs, ICP and BBB permeability caused by pneumococcal infection. The results of Western blot analysis showed BAY 11-7085 inhibited meningitis-associated increase in NF-κB activity. |

Other notes |
Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal. |
