MG132
Chemical compound
MG132 is a potent, reversible, and cell-permeable proteasome inhibitor[1] (Ki = 4 nM). It belongs to the class of synthetic peptide aldehydes.[2][3] It 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. MG132 also inhibits NF-κB activation with an IC50 of 3 μM and prevents β-secretase cleavage.
