Biological Activity

β-TrCP1 ligase inhibitor. Inhibits IκBα ubiquitination (IC50 = 5.2 μM) without affecting proteasome activity. Blocks LPS-induced expression of inflammatory cytokines in human myelomonocytic cells. Suppresses antigen-induced NFκB expression, inflammation and mucus production in airways of OVA-sensitized mice.

Programmed Cell Death

Programmed Cell Death Poster

There are two currently recognized forms of programmed cell death: apoptosis and necroptosis. This poster summarizes the signaling pathways involved in apoptosis, necroptosis and cell survival following death receptor activation, and highlights the influence of the molecular switch, cFLIP, on cell fate.
