(R)-MG132 Chemische Eigenschaften,Einsatz,Produktion Methoden

• Beschreibung

  The ubiquitin-proteasome pathway plays an integral role in the selective degradation of intracellular proteins. While important for clearing damaged or mis-folded proteins, this proteolytic pathway also regulates the availability of key proteins involved in the control of inflammatory processes, cell cycle regulation, and gene expression. (R)-MG132 is a potent, reversible, and cell permeable proteasome inhibitor. After treatment for one hour at 100 nM, it inhibits 50% and 31% of proteasome activity in lysates of J558L multiple myeloma cells and EMT6 breast cancer cells, respectively. The (R)-MG132 stereoisomer is a more effective inhibitor of chymotrypsin-like (ChTL), trypsin-like (TL), and peptidylglutamyl peptide hydrolyzing proteasome (PGPH) activities compared to (S)-MG132 (IC₅₀s = 0.22 versus 0.89 μM (ChTL); 34.4 versus 104.43 μM (TL); 2.95 versus 5.70 μM (PGPH), respectively).

• Verwenden

  (R)-MG-132 is a potent, reversible and selective tripeptide aldehyde proteasome inhibitor.

• Verwenden

  (R)-MG132 has been used in ubiquitination assay and is used as a proteasome inhibitor.

• Definition

  ChEBI: D-leucinamide, n-[(phenylmethoxy)carbonyl]-l-leucyl-n-[(1s)-1-formyl-3-methylbutyl]- is a peptide.

• Biochem/physiol Actions

  MG132 (carbobenzoxy-Leu-Leu-leucinal) is a tri-peptide aldehyde. It possesses antitumor activity and boosts cytostatic/cytotoxic effects of chemo- and radiotherapy. (R)-MG132 is a potent, membrane-permeable proteasome inhibitor. It can inhibit proteasome activity in lysates of J558L multiple myeloma cells and EMT6 breast cancer cells. The (R)-MG132 stereoisomer is a more effective inhibitor of chymotrypsin-like (ChTL), trypsin-like (TL), and peptidylglutamyl peptide hydrolyzing proteasome (PGPH) activities than the (S)-MG132.
