产品描述
Rpn11-IN-1 is an effective and selective inhibitor of proteasome subunit Rpn11 (IC50: 390 nM).
体内活性
Rpn11-IN-1 blocks the proliferation of tumor cells in culture. Rpn11 is a Zn2+-dependent metalloisopeptidase that hydrolyzes ubiquitin from tagged proteins that are trafficked to the proteasome for degradation. Rpn11-IN-1 has an IC50 of 2.1 μM and 3.8 μM against 293T and A549 cells, respectively. When inhibition of Rpn11-IN-1 against Rpn11 is measured in the presence of Zn(cyclen)2+ (100 μM), a significant loss in activity against Rpn11 is observed (IC50=77.4 μM vs. 0.39 μM). The observed IC50 value shift is attributed to the ability of Zn(cyclen)2+ to compete/titrate Rpn11-IN-1 away from Rpn11 [1].
