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.

The Josephin domain plays an important role in the cellular functions of ataxin-3, the protein responsible for the neurodegenerative Machado-Joseph disease. We have determined the solution structure of Josephin and shown that it belongs to the family of papain-like cysteine

γ-Secretase catalyzes the cleavage of the intramembrane region of the Alzheimer amyloid precursor protein (APP), generating p3, amyloid-β peptide (Aβ), and the APP intracellular domain (AICD). Although a γ-secretase inhibitor has been shown to cause an accumulation of the APP

The process of excystment of Sterkiella histriomuscorum (Ciliophora, Oxytrichidae) leads in a few hours, through a massive influx of water and the resorption of the cyst wall, from an undifferentiated resting cyst to a highly differentiated and dividing vegetative cell.
