Scientific Background Epoxomicin is a cell permeable, potent and selective proteasome inhibitor originally isolated from Actinomycetes strain based on its potent in vivo antitumor activity. It is a more potent inhibitor of the chymotrypsin-like activity of the proteasome than lactacystin. Epoxomicin also blocks trypsin-like and PGPH activities of the proteasome and regulates antigen presentation at non-toxic doses. It effectively inhibits NF-κB activation in vitro and potently blocks inflammation in vivo in the mouse ear edema assay. The ubiquitin-proteasome system (UPS) and autophagy serve as two complementary, reciprocally regulated protein degradation systems, thus inhibition of UPS by Epoxomicin activates autophagy.
