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.

Z-FF-FMK
0 ImagesCat. No.: HY-141867CAS No.: 105608-85-3Synonyms: Z-Phe-Phe-FMKZ-FF-FMK (Z-Phe-Phe-FMK) is a cell-permeable, irreversible, and cysteine protease inhibitor targeting cathepsin-L. Z-FF-FMK inhibits angiotensin II-induced MEK activation in vascular walls, aortic medial remodeling, blood pressure elevation, and upregulation of cystatin C in aortic walls. Z-FF-FMK prevents β-amyloid-mediated caspase-3 activation, poly (ADP-ribose) polymerase cleavage, DNA fragmentation, and apoptosis of cortical neurons (apoptosis). Z-FF-FMK can be used in research related to hypertension and Alzheimer's disease.
-
Z-Phe-Arg-pNA
0 ImagesZ-Phe-Arg-pNA is a substrate of Cathepsin L.
-
MeOSuc-AAPV-CMK
0 ImagesSynonyms: Elastase Inhibitor IIIMeOSuc-AAPV-CMK (Elastase Inhibitor III) is an elastase inhibitor that simultaneously inhibits Cathepsin G and Proteinase 3. MeOSuc-AAPV-CMK blocks the shedding of FcgRIIIb on the surface of human neutrophils. MeOSuc-AAPV-CMK reverses the elastase-mediated reduction in proinflammatory cytokine production by immune cells, partially restores IL-1β levels in immune cell co-culture systems, and prevents elastase-mediated adiponectin cleavage.

Cathepsin C-IN-5
0 ImagesCat. No.: HY-146584CAS No.: 2825567-97-1Cathepsin C-IN-5 (compound SF38) is a potent, selective and orally active Cathepsin C inhibitor with IC50s of 59.9 nM, 4.26 µM, >5 µM, >5 µM, >5 µM for Cat C, Cat L, Cat S, Cat B, Cat K, respectively. Cathepsin C-IN-5 inhibits the Cat C activity in bone marrow and blood. Cathepsin C-IN-5 decreases the activation of NSPs (neutrophil serine proteases). Cathepsin C-IN-5 shows anti-inflammatory activity.
