Application

CA-074 has been used as a cathepsin B inhibitor:
  • to study its effect on pseudotyped viruses bearing S proteins harboring R642M and N714K using HeLa cells
  • to determine the role of autophagy in glucose deprivation (GD)-induced damage
  • to study its effects on neuronal function upon exposure to His-cathepsin B (CATB)

Biochem/physiol Actions

CA-074 is a potent and a selective inhibitor of cathepsin B. It is useful to study the biological function of cathepsin B in vivo. Studies show that CA-074 can also inhibit cathepsin L under reducing conditions.
