Background:

BAY 11-7085 is an inhibitor of NF-κB activation and phosphorylation of IκBα; it stabilizes IκBα with an IC50 of 10 μM.

BAY 11-7085 inhibits TNFa-induced surface expression of E-selectin, VCAM-1, and ICAM-1with IC50 values in the range of 5-10 μM. BAY 11-7085 stabilizes IκBα in a dose-dependent manner with an IC50 value of approximately 10 μM. There is a clear correlation between the concentration of drug that stabilized IκBα, the concentration that inhibits nuclear levels of NF-kB, and the concentration that inhibits adhesion molecule expression[1]. BAY 11-7085 has been shown to inhibit cell proliferation and induce apoptosis of a variety of cells. BAY 11-7085 (ECSCs) significantly inhibits the cell proliferation and DNA synthesis of ovarian endometriotic cyst stromal cells and induces apoptosis and the G0/G1 phase cell cycle arrest of these cells. BAY 11-7085 induces apoptosis of ECSCs by suppressing antiapoptotic proteins, and that caspase-3-, -8-, and -9-mediated cascades are involved in this mechanism[2].

BAY 11-7085 acts as an anti-inflammatory agent in both the rat carrageenan paw and the rat adjuvant arthritis model. It demonstrates a dose-dependent reduction in swelling in the rat carrageenan paw model[1].
