MG-132是一种蛋白酶体抑制剂，IC50为100 nM，也抑制钙蛋白酶，IC50为1.2 μM。MG132通过诱导细胞周期停滞以及引发细胞凋亡来抑制HeLa细胞的生长。MG-132 (10 μM) 通过抑制蛋白酶体介导的IκBα降解，有效抑制A549细胞中TNF-α诱导的NF-κB活化。MG132可以抑制NLRP1的活化。体内研究中，MG-132（ip，0.1 mg/kg/day）通过调节ERK1/2和JNK1信号通路，减轻压力超负荷引起的心脏肥大。MG-132治疗通过下调肌肉特异性泛素连接酶atrogin-1/MAFbx 和MuRF-1 mRNA，显著减少小鼠体内固定化诱导的骨骼肌萎缩。

MG-132

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 potent proteasome and calpain inhibitor with IC₅₀s of 100 nM and 1.2 μM, respectively. MG-132 effectively blocks the proteolytic activity of the 26S proteasome complex. MG-132, a peptide aldehyde, also is an autophagy activator. MG-132 also induces apoptosis.

体外研究

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.
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 IC₅₀ of 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].

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].
