Argyrin B

Argyrin B, a natural product cyclic peptide, is a reversible, non-competitive immunoproteasome inhibitor. Argyrin B shows selective inhibition of the β5i and β1i sites of the immunoproteasome over the β5c and β1c sites of the constitutive proteasome with nearly 20-fold selective inhibition of β1i over the homologous β1c. Argyrin B has antibacterial effects[1].
