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.

A series of new epoxysuccinyl peptides were designed and synthesized to develop a specific inhibitor of cathepsin B. Of these compounds, N-(L-3-trans-ethoxycarbonyloxirane-2-carbonyl)-L-isoleucyl-L-proli ne (compound CA-030) and N-(L-3-trans-propylcarbamoyloxirane-2-carbonyl)-L-isoleucyl-L-prol ine (compound CA-074) were the most potent and specific inhibitors of cathepsin B

Human coronavirus 229E (HCoV-229E), a causative agent of the common cold, enters host cells via two distinct pathways: one is mediated by cell surface proteases, particularly transmembrane protease serine 2 (TMPRSS2), and the other by endosomal cathepsin L. Thus, specific

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.

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
