Epoxomicin | Irreversible 20S proteasome inhibitor

Epoxomicin (134381-21-8) is a potent, selective and cell permeable irreversible inhibitor of the 20S proteasome.1 It does not inhibit non-proteasomal proteases such as papain, chymotrypsin, trypsin, calpain and cathepsin B at concentrations up to 50 μM.1 Epoxomicin was isolated from Actinomycete strain Q996-17 and displayed in vivo antitumor activity against B16 melanoma cells.2 Epoxomicin caused a progressive model of Parkinson's disease in various systems.3,4,5 This model has been disputed.6,7
