We reported the synthesis, characterization and biological activity of several copper(II) Schiff base complexes, which exhibit high proteasome inhibitory activities with particular selectivity of beta(2) subunit. Structure-activity relationships information obtained from complex Na-2[Cu(a4s1)] demonstrated that distinct bonding modes in beta(2) and beta(5) subunits determines its selectivity and potent inhibition for beta(2) subunit.
