Chemical structure of bortezomib, the first proteasome inhibitor approved for use.

Proteasome inhibitors are drugs that block the action of proteasomes, cellular complexes that break down proteins, like the p53 protein. Proteasome inhibitors are being studied in the treatment of cancer, especially multiple myeloma.

Examples[edit]

  • The first non-peptidic proteasome inhibitor discovered was the natural product lactacystin.[1]
  • In 2003, bortezomib was the first proteasome inhibitor to be approved for use in the U.S.
  • carfilzomib was approved by the FDA for relapsed and refractory multiple myeloma on 20 July 2012.
  • MG132 is a synthesized peptide commonly used for in vitro studies.
