General description

A potent, irreversible inhibitor of Cathepsin B in vivo and in vitro (IC50 = 2.24 nM for rat liver cathepsin B).
An epoxysuccinyl peptide that acts as a potent, irreversible, and specific inhibitor of cathepsin B (IC50 = 2.24 nM for rat liver cathepsin B). Reduces ischemia-induced neuronal death. Exhibits lower membrane permeability when compared to CA-074 Me (Cat. No. 205531).
