Description

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-κB activation (IC₅₀ = 3 µM). This material is ≥95% pure by HPLC. A material with ≥98% purity by HPLC (Cat. No. 474790) is also available. Also available as a 20 mM solution in DMSO (Cat. No. 474788).
