Product Description
Cell permeable, potent and selective proteasome inhibitor originally isolated from Actinomycetes strain based on its potent in vivo antitumor activity. More potent inhibitor of the chymotrypsin-like activity of the proteasome than lactacystin. Effectively inhibits NF-κB activation in vitro and potently blocks inflammation in vivo in the mouse ear edema assay.

Product Description
Cell permeable and irreversible proteasome inhibitor. Specifically inhibits 26S proteasome (MCP; multicatalytic proteinase complex). Blocks proteasome activity by targeting the catalytic β-subunit. Has no effect on serine or cysteine proteases. Induces apoptosis in human monoblast U937 cells. Also inhibits NF-κB activation by inhibiting IκB degradation. Inhibits the ubiquitin proteasome pathway in cell culture (IC50=10µM).  Inhibits cathepsin A . Upregulates HSP70 and HSP22, suggesting an initial neuroprotective pathway.
