MG-132 Chemical Structure
Bortezomib also known as Velcade, MG-341, PS-341 is proteasome Inhibitor, effectively inhibits proteasome activity (Ki-0.6 nM).
CEP-18770 is a potent chymotrypsin-like proteasome inhibitor with IC50 of 3.8 nM.
Danoprevir is a peptidomimetic inhibitor of the NS3/4A protease of hepatitis C virus (HCV) with an IC50 of 0.2-3.5 nM.
Nafamostat is an anticoagulant.

Danoprevir is a peptidomimetic inhibitor of the NS3/4A protease of hepatitis C virus (HCV) with an IC50 of 0.2-3.5 nM.
Ritonavir is an inhibitor of HIV protease used to treat HIV infection and AIDS.
Glimepiride is a medium-to-long acting sulfonylurea anti-diabetic compound with an ED50 of 182 μg/kg.
MG132 is a potent cell-permeable proteasome and calpain inhibitor with IC50 of 0.1 and 1.2 μM for the inhibition of proteasome and calpain, respectively. The Ki of MG132 is 4 nM. MG132 inhibits TNF-α-induced NF-κB activation and IκBα degradation with an IC50 of 3 µM and prevents β-secretase cleavage. MG132 induces neurite outgrowth in PC12 cells and has anticancer properties in vitro. MG132 reduces the degradation of ubiquitin-conjugated proteins in mammalian cells and permeable strains of yeast by the 26S complex without affecting its ATPase or isopeptidase activities. MG132 activates c-Jun N-terminal kinase (JNK1), which initiates apoptosis. [1][2][3]

| Truncated mouse Period2 (Per2) protein was expressed in NIH3T3 cells, treated by cycloheximide with or without MG132 for 1 – 4 hours.Per2 was reported to be degraded by the proteasome proteolysis. By adding MG132 (25 mM), a proteasome inhibitor, the degradation of Per2 was dramatically decreased within 4 hours treatment (shown by western blot). |
