一般描述
Epoxomicin is a linear peptide consisting of a threonine or serine residue with α′, β′-epoxyketone derived from leucine or a γ,δ-dehydroleucine. It is a natural product isolated from Actinomyces sp., and is a cell-permeable, potent, selective and irreversible proteasome inhibitor.
应用
Epoxomicin has been used:
- as an ubiquitin–proteosome system (UPS) inhibitor in pheochromocytoma PC12 cells
- as a proteasome inhibitor in mammary epithelial MCF-10A cells
- as a proteasome inhibitor in chymotryptic assay in cardiomyocytes
生化/生理作用
Epoxomicin binds covalently to the catalytic subunits of proteasome. It forms an adduct with target proteins. It inhibits chymotrypsin-like activity of the proteasome. Epoxomicin also inhibits the nuclear factor κ light chain enhancer of activated B cells (NF-κB) mediated proinflammatory signalling pathway. It is also a potent antitumor and anti-inflammatory agent.
Epoxomicin, a natural product isolated from Actinomyces sp., is a cell-permeable, potent, selective and irreversible proteasome inhibitor.
