Application

CA-074 methyl ester has been used as cathepsin B inhibitor in cardiomyocytes, HeLa cells and human pancreatic cancer PANC-1 cells.

Biochem/physiol Actions

CA-074 methyl ester is a cell-permeable analog of CA-074. It is an inhibitor of cathepsin B especially the intracellular type. and undergoes intracellular transition into active CA-074 by the action of esterases. CA-074 methyl ester also inhibits cathepsin L.
