Peptide-semicarbazones derived from Z-Trp-Trp-Phe-aldehyde inhibit the chymotryptic activity of the human proteasome at nanomolar concentrations, but are less active in a NFkappaB reporter gene assay. Cyclic semicarbazones, in contrast, combine a strong inhibitory effect on the enzyme with an inhibition
