The natural proteasome inhibitor salinosporamide A from the marine bacterium Salinispora tropica is a promising drug candidate for the treatment of multiple myeloma and mantle cell lymphoma. Using a comprehensive approach that combined chemical synthesis with metabolic engineering, we generated a series of salinosporamide analogues with altered proteasome binding affinity. One of the engineered compounds is equipotent to salinosporamide A in inhibition of the chymotrypsin-like activity of the proteasome, yet, exhibits superior activity in the cell-based HCT-116 assay.
