| Application: | Lactacystin has been used: • as a proteasome inhibitor to inhibit protein degradation • to inhibit proteasomal activity of cells for live cell imaging • to block proteasomal proteolysis in human monocyte-derived dendritic cells (MoDCs) for 24 h • to provide unilateral injection to animals to induce nigrostriatal lesions |
| Biochem/physiol Actions: | Lactacystin can block the development of cell cycle and stimulate differentiation in a murine neuroblastoma cell line. It can serve as a precursor for clasto-lactacystin β-lactone. Cell-permeable and irreversible proteasome inhibitor (Ki = 4nM). Inhibits NF-kB activation (IC50 = 10mM). Induces neurite outgrowth in neuro2A mouse neuroblastoma cells. |
