Synonyms : N,N'-((2S,2'S)-(((1R,1'R)-Peroxybis(3-methylbutane-1,1-diyl))bis(azanediyl))bis(1-oxo-3-phenylpropane-1,2-diyl))bis(pyrazine-2-carboxamide)

Applications : This is an impurity of Bortezomib, which is a potent 20S proteasome inhibitor. It exhibits favorable selectivity towards tumor cells over normal cells. Bortezomib inhibits NF-κB and induces ERK phosphorylation to suppress cathepsin B and inhibit the catalytic process of autophagy in ovarian cancer and other solid tumors.
