Epoxomicin

Cell permeable: no

Primary Target
CT-L,T-L,PGPH activity of proteasome

Product does not compete with ATP.

Reversible: no

Toxicity: Standard Handling (A)

An antitumor agent of microbial origin that acts as a potent, highly specific, and irreversible inhibitor of chymotrypsin-like (CT-L), trypsin-like (T-L), and peptidylglutamyl peptide hydrolyzing (PGPH) activities of the proteasome. Modifies the proteasomal catalytic subunits LMP-7, MECL1, and Z. Epoxomicin also displays potent anti-inflammatory activity in vivo.

An antitumor and anti-inflammatory agent that acts as a potent, highly specific, and irreversible inhibitor of chymotrypsin-like (CT-L), trypsin-like (T-L), and peptidyl-glutamyl peptide hydrolyzing (PGPH) activities of the proteasome. Modifies the proteasomal catalytic subunits LMP-7, MECL1, and Z. Does not affect the activities of non-proteasomal proteases such as trypsin, cathepsin B, or chymotrypsin. A 1 mM (50 µg/90 µl) solution of Epoxomicin, Synthetic (Cat. No. 324801) in DMSO is also available.
