MG-115 is a potent and reversible proteasome inhibitor, with Kis of 21 nM and 35 nM for 20S and 26S proteasome, respectively. MG-115 specifically inhibit the chymotrypsin-like activity of the proteasome, induces p53-dependent apoptosis[1][2][3].

In Vitro	MG-115 (0.1-10 μM; 24 h) dose-dependently decreases the viability of HepG2 cells[3]. MG-115 (0.1-10 μM; 24 h) amplifies the reporter gene expression mediated by CWK18 DNA condensates[3]. Cell Viability Assay[3] Cell Line: HepG2 cells Concentration: 0.1, 1, 2, 5, 10 μM Incubation Time: 24 hours Result: Dose-dependently decreased cell viability. Inhibited the proteasomal activity, with an IC50 of 2 μM.
