Abstract
The ubiquitin-proteasome pathway was recently identified as a promising new therapeutic target in cancer treatment. An increased proteasome activity was described in certain cancer types, especially in multiple myeloma (MM) and also in mantle cell lymphoma (MCL). The proteasome inhibitor bortezomib has been approved for the treatment of refractory MM and has also shown reproducible activity in MCL. Recently we described a novel tripeptide compound, BSc2118, with inhibitory activity against all three proteolytic activities (post-glutamyl peptide hydrolase-like, trypsin-like and chymotrypsin-like activities) of the 20S proteasome (
