myeloma and mantle cell lymphoma. Proteasomeinhibitors that selectively target combinations of β1c/β1i, β2c/β2i, or β5c/β5i are available, yet ligands truly selective for a single proteasome activity are scarce. In this work we report the development of cell-permeable β1i and β5iselectiveinhibitors that outperform existing leads in terms of selectivity and/or potency. These compounds are the result

Mammals express seven different catalytically active proteasome subunits. In order to determine the roles of the different proteolytically active subunits in antigen presentation and other cellular processes, highly specific inhibitors and activity-based probes that selectively target specific active sites are needed. In this work we present the development of fluorescent activity-based probes that selectively target the β1 and β5 sites of the constitutive proteasome.
