产品介绍
MG-132 (Z-Leu-Leu-Leu-al) 是一种有效的,可逆的蛋白酶体 (proteasome) 抑制剂,IC50为 100 nM。MG-132 有效阻断 26S 蛋白酶体复合物的蛋白水解活性。MG-132 是一种肽醛,是自噬 (autophagy) 激活剂。MG-132 还诱导凋亡 (apoptosis)。
生物活性

MG-132 (Z-Leu-Leu-Leu-al) is a potentproteasomeandcalpaininhibitor withIC50s of 100 nM and 1.2 μM, respectively. MG-132 effectively blocks the proteolytic activity of the 26Sproteasomecomplex. MG-132, a peptide aldehyde, also is anautophagyactivator. MG-132 also inducesapoptosis[1][2][3].

IC50& Target

IC50: 100 nM (Proteasome), 1.2 μM (Calpain)[1][3]

体外研究
(In Vitro)

MG-132 (Z-Leu-Leu-Leu-al) initiates neurite outgrowth in PC12 cells at a low concentration (30 nM) and is a very strong inhibitor of 20S proteasome[3].
MG-132 (10 μM; 1 hour) reverses the effects of TNF- α on I κ B degradation and NF-κ B activation in A549 cells[4].
MG-132 (0.75-5 μM; 24 hours) potently induces p53-dependent apoptosis in KIM-2 cells by 26S proteasome inhibition[5].
MG-132 (10-40 μM; 24 hours) significantly reduces the viability of C6 glioma cells in both time- and concentration-dependent manners and shows the IC50of 18.5 μM at 24 hours[6].
MG-132 (18.5 μM; 24 hours) induces down-regulation of anti-apoptotic proteins Bcl-2 and XIAP and up-regulates expression of pro-apoptotic protein Bax and caspase-3[6].

Cell Viability Assay[3]

Cell Line:C6 glioma cells
Concentration:10, 20, 30, 40 μM
Incubation Time:24 hours
Result:Significantly reduced the viability of C6 glioma cells beginning at 6 h in both time- and concentration-dependent manners and showed the IC50of 18.5 μM at 24 hours.

Western Blot Analysis[3]

Cell Line:A549 cells
Concentration:10 μM
Incubation Time:1 hour
Result:Reversed the effects of TNF-α on IκB degradation and resulted in a reversal of TNF-α-induced NF-κB activation.
体内研究
(In Vivo)

MG132 (10 mg/kg; i.p.; daily for 25 days starting 5 days after EC9706 cells injection) significantly inhibits tumor growth of the EC9706 xenograft without causing toxicity to mice[7].
MG-132 (1 mg/kg; i.v.; twice a week for 4 weeks) shows potent tumor inhibitory effect against mice bearing HeLa tumors[8].
MG-132 (1-10 μg/kg/24 hours; subcutaneously implanted osmotic pumps; for 8 days) greatly increases the expression levels of β-dystroglycan, α-dystroglycan, α-sarcoglycan, and dystrophin in skeletal muscle lysates in mice (six-month-old male C57BL/10ScSn DMD mdx mice)[9].

Animal Model:5- to 6-weeks old female athymic nude mice (EC9706 xenograft)
Dosage:10 mg/kg
Administration:I.p.; daily for 25 days starting 5 days after EC9706 cells injection
Result:Significantly inhibited tumor growth of the EC9706 xenograft without causing toxicity to the mice.
Animal Model:Five-week-old female C.B-17/lcr-scid/scidJcl mice (bearing HeLa cells)[8]
Dosage:1 mg/kg
Administration:Intravenous injection; twice a week for 4 weeks
Result:The growth inhibition rates in HeLa tumors was 49% compared to the control.
