          MG132 (MG-132, Z-Leu-Leu-Leu-al, Z-Leu-Leu-Leu-CHO)是強(qiáng)效的、可逆的細(xì)胞通透性proteasome抑制劑(IC50 = 100 nM),抑制20S蛋白酶體的ZLLL-MCA降解活性時(shí),比ZLLal有效1000多倍。MG132也可以抑制細(xì)胞周期和細(xì)胞周期蛋白降解所需要的calpain (IC50 = 1.2 μM),并誘導(dǎo)PC12細(xì)胞中神經(jīng)突增生。另外,MG132抑制IκBα降解,從而抑制NF-κB通路活化。MG132誘導(dǎo)MPM細(xì)胞凋亡,并伴隨caspase 3、7、8、9蛋白活化。MG132還誘導(dǎo)線粒體膜電位變化,而且細(xì)胞內(nèi)ROS水平也會(huì)提高。
