MG-132 is a potent proteasome and calpain inhibitor with IC50 values of 100nM and 1.25μM, respectively[1]. MG-132 can cause upregulation of Nrf2-dependent antioxidative function and downregulation of NF-κB-mediated inflammation[2]. MG-132 has been widely used to alleviate the progression of arthritis and pain in rats[3].
In vitro, MG-132 treatment for 24 hours significantly inhibited the proliferation of C6 cells, with an IC50 value of 18.5μM[4]. Treatment with 1μM MG-132 for 24 hours significantly induced apoptosis in U87MG cells and A172 cells, accompanied by an increase in mitochondrial membrane potential and nuclear translocation of mitochondrial protein AIF[5]. Treatment with 1μM MG-132 for 24 hours significantly inhibited DNA synthesis in SW1116 and HT-29 cells and activated the BMP signaling pathway, resulting in cell growth inhibition[6].
In vivo, MG-132 treatment via intraperitoneal injection at a dose of 10μg/kg/day for 7 days significantly improved the cardiac function of the mouse model of myocarditis induced by Coxsackievirus B3 and inhibited the structural remodeling of the ventricle[7]. A single intraperitoneal injection of MG-132 at a dose of 9mg/kg for 6 hours significantly mitigated the liver swelling, degeneration and inflammatory cell infiltration in the acute liver injury mouse model[8].

Preparation Method |
Female athymic nude mice (6-weeks old) were housed under controlled temperature (21-23°C), humidity (30-35%) and light cycle (7:00 AM to 7:00 PM) and maintained on a standard rodent diet. Mice were inoculated intraperitoneally (i.p.) with 7×106 EC9706 cells, after which mice received injections with vehicle or MG-132 (10mg/kg/day; i.p.) for 25 days starting 5 days after the injection of EC9706 cells. Mice were fed with antioxidant-free AIN-76A special diet for a week before starting the experiment. Analyze the tumor volume of the mice every five days. |

Dosage form |
10mg/kg/day; 25 days; i.p. |
|
Applications |
MG-132 treatment significantly inhibited tumor growth in the EC9706 xenograft mouse model. |
