MG 132 is a specific inhibitor of the chymotrypsin-like activity of the 20S proteasome  with an IC50 of 100 nM with Z-LLL-AMC as the substrate. MG 132 also inhibits calpain, suppresses gastric cancer cell proliferation and induces macro-autophagy.  It also inhibits TNF-α-induced NF-κB activation and IκBα degradation and induces neurite outgrowth in PC12 cells.  MG 132 inhibits SARS-CoV-2 Mpro in vitro and can inhibit viral replication.
