Additional Information:

MG-132 (133407-82-6) is a specific inhibitor of the chymotrypsin-like activity of the 20S proteasome (IC50=100 nM with Z-LLL-AMC as substrate).1 Also inhibits calpain (IC50=1.25 μM)1 Suppresses gastric cancer cell proliferation and induces macro-autophagy2. Activates stress kinases and induces Hsp72.3 Induces neurite outgrowth.1 MG-132 blocks NFκB activation by blocking IκB proteolysis (IC50=3 μM).4 Cell permeable.
