A potent, reversible proteasome inhibitor with Ki of 21nM for 20S proteasome and 35nM for 26S proteasome. The inhibition of proteasome was through specific inhibition of chymotrypsin-like activity of the proteasome. Also shown to induce apoptosis in Rat-1 and PC12 cells via a p3-independent pathway.
