Opis ogólny

Lactacystin is an antibiotic and a metabolite of Streptomyces spp.

Zastosowanie

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

Działania biochem./fizjol.

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.
