产品描述

MG 132(同义名: Z-Leu-Leu-Leu-CHO,  MG-132, MG132)是一种强效的,可逆的,细胞通透性良好的蛋白酶体抑制剂(IC50 = 100 nM),其通过与20S26S蛋白酶体结合并使其失活[1],也可以抑制细胞周期和细胞周期蛋白降解所需要的calpain(IC50 = 1.2 μM) [2],通过阻止IκB降解来抑制NF-κB活化(IC50=3µM[3]。在体外实验中, MG132能有效诱导caspase激活的肿瘤细胞的凋亡并抑制肿瘤侵袭[4]。另外,MG 132可以抑制β分泌酶(β-secretase)分裂[5]和刺激PC12细胞中神经细胞生长[6]
