Descrição

Descrição geral

Epoxomicin is a linear peptide consisting of a threonine or serine residue with α′, β′-epoxyketone derived from leucine or a γ,δ-dehydroleucine.[1] It is a natural product isolated from Actinomyces sp., and is a cell-permeable, potent, selective and irreversible proteasome inhibitor.[2]

Aplicação

Epoxomicin has been used:

• as an ubiquitin–proteosome system (UPS) inhibitor in pheochromocytoma PC12 cells[3]
• as a proteasome inhibitor in mammary epithelial MCF-10A cells[4]
• as a proteasome inhibitor in chymotryptic assay in cardiomyocytes[5]

Ações bioquímicas/fisiológicas

Epoxomicin binds covalently to the catalytic subunits of proteasome.[2] It forms an adduct with target proteins.[1] It inhibits chymotrypsin-like activity of the proteasome.[6] 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.[2]

Epoxomicin, a natural product isolated from Actinomyces sp., is a cell-permeable, potent, selective and irreversible proteasome inhibitor.
