Here we report that organic copper complexes can potently and selectively inhibit the chymotrypsin-like activity of the proteasome in vitro and in vivo. Several copper compounds, such as NCI-109268 and bis-8-hydroxyquinoline copper(II) [Cu(8-OHQ)(2)], can inhibit the chymotrypsin-like activity of purified
