Biochem/physiol Actions

Target IC₅₀: 3 µM in inhibiting NF-κB activation

Reversible: yes

Product does not compete with ATP.

Target K_i: 4 nM as proteasome inhibitor

Cell permeable: yes

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) and inhibits NF-κB activation (IC₅₀ = 3 µM).
