CA-074 Me is a membrane-permeable and selective inhibitor of cathepsin B with IC50 value of 36.3 nM [1, 2].
CA-074 Me is a methyl ester derivative of CA-074. In cultured human gingival fibroblasts, CA-074 Me exerted a 95% inhibition of cathepsin B and partial inhibition (54%) of the combined activities of cathepsins B and L. CA-074 Me was also found to inhibit cathespin L under reducing conditions. It inhibited the activity of purified human cathepsin L by more than 90% when the enzyme had been pre-incubated with 1.4 mM DTT or 4.2 mM GSH for 2 hours. Besides that, CA-074 Me completely inhibited cathepsin B in the presence of 1.4 mM DTT [2, 3].
