生物活性

Marizomib (Salinosporamide A) is a second-generation, irreversible, brain-penetrant, pan-proteasome inhibitor. Marizomib inhibits the CT-L (β5), CT-T-laspase-like (C-L, β1) and trypsin-like (T-L, β2) activities of the 20S proteasome (IC50=3.5, 28, and 430 nM, respectively).

性状

Solid

IC50 & Target[1][2]

IC50: 3.5 nM (CT-L), 28 nM (CT-T-laspase-like), 430 nM (trypsin-like)

体外研究(In Vitro)

Marizomib (Salinosporamide A) (0.1-10000 nM; 72 hours) effectively reduces survival of D-54 and U-251 cells in a dose-dependent manner. The IC50s are ~52 nM for U-251 and ~20 nM for D-54.
Marizomib (24 hours; 60 nM) induces apoptosis and caspase-3 activation in glioma cells.

Medlife has not independently confirmed the accuracy of these methods. They are for reference only.

1:一般建议:溶解度为Medlife测试数据,可能与文献描述存在差异。这是由于生产工艺和批次不同产生的正常现象。为了使其更好的溶解,请用37℃加热试管并在超声波水浴中震动片刻。不同批次产品溶解度各有差异,仅做参考,具体以实验方案为准。

2:储存条件:粉末-20°C一般情况可以保存3年,溶于溶剂-80°C一般情况可以保存1年。不同产品及不同批次产品可能存在差异,请细致阅读产品信息,并辅助参考相关文献描述。
