Proteasomal processing is conducted by three individual catalytic subunits, namely β11, β2, and β5. Subunit-specific inhibitors are useful tools in dissecting the role of these individual subunits and are leads toward the development of antitumor agents. We here report that the presence of fluorinated phenylalanine derivatives in peptide based proteasome inhibitors has a profound effect on inhibitor potency and selectivity. Specifically, compound 4a emerges as one of the most β5 specific inhibitors known to date.
