Cell-permeable, irreversible ubiquitin-activating enzyme (E1) inhibitor (IC50 < 10 μM). Blocks ubiquitination and prevents ubiquitin-mediated proteasomal degradation. Inhibits NF-κB activation, blocks degradation of p53, increases p21 levels and induces apoptosis in vitro. Also causes an increase in sumoylation of proteins.
