Cathepsin
Cathepsins are protease enzymes, categorized into multiple families. Cathepsins can be serine protease, cysteine protease, or aspartyl protease. There are about 15 classes of cathepsins in humans (Cathepsin A, B, C, D, E, F, G, H, K, L, O, S, V, W, and Z). Cathepsins are active in the low pH milieu of lysosomes and are versatile in their functions. Like other enzymes, they are vital for the normal physiological functions such as digestion, blood coagulation, bone resorption, ion channel activity, innate immunity, complement activation, apoptosis, vesicular trafficking, autophagy, angiogenesis, proliferation, and metastasis, among scores of others.
Numerous pathologies have been attributed to the dysregulated cathepsins, some of which include arthritis, periodontitis, pancreatitis, macular degeneration, muscular dystrophy, atherosclerosis, obesity, stroke, Alzheimer's disease, schizophrenia, tuberculosis, and Ebola.

Cathepsin E substrate e
0 ImagesCat. No.: HY-P10922CAS No.: 1246741-19-4Cathepsin E substrate e is a substrate of Cathepsin E. Cathepsin E substrate e was designed in such a way that due to the close proximity of a Mca-donor and a Dnp-acceptor, a near complete intramolecular quenching effect was achieved in its intact state. After the proteolytic cleavage of the hydrophobic motif of the peptide substrate, both Mca and Dnp would be further apart, resulting in bright fluorescence.

Verducatib
0 ImagesVerducatib (BI 1291583) is an orally active inhibitor of cathepsin C (also known as DPP1). Verducatib restores the protease-inhibitor balance by inhibiting the activation of neutrophil serine proteases, thereby alleviating pulmonary inflammation and regulating infection responses. Verducatib significantly reduces the risk (including severe exacerbations) and frequency of acute exacerbations in bronchiectasis (BE). Verducatib also improves lung function and quality of life, and shortens the duration of antibiotic use. The overall incidence of adverse events of Verducatib is comparable to that of placebo, with only slightly more mild-to-moderate cutaneous adverse events observed in the high-dose group, demonstrating promising clinical application potential.
