“The boron atom in bortezomib is proposed to bind the catalytic site of the 26S proteasome with high affinity and specificity. In normal cells, the proteasome regulates protein expression and function by degradation of ubiquitylated proteins, and also rids the cell of abnormal or misfolded proteins. Clinical and preclinical data support a role for the proteasome in maintaining the immortal phenotype of myeloma cells, and cell-culture and xenograft data support a similar function in solid tumor cancers. While multiple mechanisms are likely to be involved, proteasome inhibition may prevent degradation of pro-apoptotic factors, thereby triggering programmed cell death in neoplastic cells. Bortezomib causes a rapid and dramatic change in the levels of intracellular peptides that are produced by the proteasome. Some intracellular peptides have been shown to be biologically active, and so the effect of bortezomib on the levels of intracellular peptides may contribute to the biological and/or side effects of the drug.”
