|Product Specification Sheet|
- Potent, irreversible inhibitor of all the 3 proteolytic activities of the mammalian 20S proteasome.
- β5 subunit: chymotrypsin-like (EC50 = 3.5nM)
- β2 subunit: trypsin-like (EC50 = 28nM)
- β1 subunit: caspase-like or peptidyl-glutamyl peptide-hydrolyzing (PGPH) (EC50 = 430nM)
- Potent anticancer compound.
- Triggers apoptosis, with distinct proteasome activity and mechanism of action compared to bortezomib (Velcade) (Prod. No. AG-CR1-3602).
- Most potent suppressor of NF-κB activation, compared with bortezomib, MG-132 (Prod. No. AG-CP3-0011), N-acetyl-leucyl-leucyl-norleucinal (ALLN) and lactacystin (Prod. No. AG-CN2-0104).
- Inhibitor of TNF-α, IL-1, IL-6, ICAM-1 and VEGF synthesis.
- Displays a longer inhibition duration than bortezomib.
- Potent antileukemic activity against bortezomib-resistant leukemia cells.
