Peptide-based compounds including heteroatom-containing, three-membered rings efficiently and selectively inhibit specific activities of N-terminal nucleophile (Ntn) hydrolases. The activities of those Ntn having multiple activities can be differentially inhibited by the compounds described. For example, the chymotrypsin-like and PGPH activities of the 20S proteasome can be selectively inhibited with the inventive compounds. The peptide-based compounds include an electron withdrawing group adjacent to the ring functionality, and the peptide include at least three peptide units. Among other therapeutic utilities, the peptide-based compounds exhibit anti-inflammatory and inhibition of cell proliferation, involving therapeutic applications for these compounds.
