| | MG-132 Usage And Synthesis |
| Description | MG-132 (133407-82-6) is a specific inhibitor of the chymotrypsin-like activity of the 20S proteasome (IC50=100 nM with Z-LLL-AMC as substrate).1 Also inhibits calpain (IC50=1.25 μM).1 Suppresses gastric cancer cell proliferation and induces macro-autophagy.2 Activates stress kinases and induces Hsp72.3 Induces neurite outgrowth.1 MG-132 blocks NFκB activation by blocking IκB proteolysis (IC50=3 μM).4 Cell permeable. | | Uses | A proteasome and NF-κB inhibitor. | | Uses | MG 132 is a potent, membrane-permeable proteasome inhibitor. It induces neurite outgrowth in PC12 cells. Neuroprotective product. | | Definition | ChEBI: A tripeptide that is L-leucyl-L-leucyl-L-leucine in which the C-terminal carboxy group has been reduced to the corresponding aldehyde and the N-terminal amino group is
protected as its benzyloxycarbonyl derivative. | | General Description | Potent, reversible, and cell-permeable proteasome inhibitor (Ki = 4 nM). Reduces the degradation of ubiquitin-conjugated proteins in mammalian cells and permeable stains of yeast by the 26S complex without affecting its ATPase or isopeptidase activities. Activates c-Jun N-terminal kinase (JNK1) and inhibits NF-κB activation (IC50 = 3 μM). | | Biological Activity | Potent cell-permeable inhibitor of proteasome (IC 50 = 100 nM) and calpain (IC 50 = 1.2 μ M). Inhibits TNF- α -induced NF- κ B activation and I κ B α degradation. Induces neurite outgrowth in PC12 cells and has anticancer properties in vitro . | | Biochem/physiol Actions | Cell permeable: yes | | storage | -20°C (desiccate) | | Background | MG-132 is a potent proteasome and calpain inhibitor. Research studies have shown that MG-132 prevents degradation of the proteasome substrates SucLLVY-MCA and ZLLL-MCA with an IC50 of 850 nM and 100 nM, respectively, as well as inhibits casein-degrading activity of m-calpain with an IC50 of 1.25 µM. Investigators have demonstrated that MG-132 inhibits TNF-α-induced NF-κB activation and IL-8 release in A549 cells. Proteasome inhibition with MG-132 prevents degradation of short-lived proteins, which correlates with increased expression of HSP and ER chaperone proteins. MG-132 induces apoptosis in Hep G2 cells in a time- and dose-dependent manner. Proteasome inhibitors like MG-132 are important research tools for studying cellular degradation of the ubiquitin-proteasome pathway. | | References | [1] S TSUBUKI.
