General description

Potent, reversible, and cell-permeable proteasome inhibitor (K_i = 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) which initiates apoptosis. Inhibits NF-kB activation (IC₅₀ = 3 µM). Also reported to increases the survival rate of mesenchymal stem cells following their transplantation.
