EPOXOMICIN Chemical Properties,Usage,Production

Description

Epoxomicin (134381-21-8) is a potent, selective and cell permeable irreversible inhibitor of the 20S proteasome.1 It does not inhibit non-proteasomal proteases such as papain, chymotrypsin, trypsin, calpain and cathepsin B at concentrations up to 50 μM.1 Epoxomicin was isolated from Actinomycete strain Q996-17 and displayed in vivo antitumor activity against B16 melanoma cells.2 Epoxomicin caused a progressive model of Parkinson’s disease in various systems.3,4,5 This model has been disputed.6,7

Uses

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

Uses

In studies of proteasome biology.

Definition

ChEBI: A tripeptide consisting of an Ile-Ile-Thr-NH2 sequence N-substituted on the threonamide amidic nitrogen with a (2S)-4-methyl-1-[(2R)-2-methyloxiran-2-yl]-1-oxopentan-2-yl group and with acetyl and meth l groups on the nitrogen of the isoleucine residue distal to the threonamide; a naturally occurring selective proteasome inhibitor with anti-inflammatory activity.

General Description

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.

Biochem/physiol Actions

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.
