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.

Y1693
0 ImagesY1693 is an orally active RANKL inhibitor with a Kd of 5.03 μM for hRANKL. Y1693 inhibits the activation of the downstream c-fos/NFATc1 signaling pathway by blocking its interaction with RANK. Y1693 significantly inhibits RANKL-induced osteoclast differentiation, F-actin ring formation and bone resorptive activity, while downregulating the mRNA and protein expressions of TRAP, cathepsin K, c-fos and NFATc1. Y1693 shows no obvious cytotoxicity to bone marrow-derived macrophages and osteoclast precursor cells, and exhibits favorable ADME properties. Y1693 improves ovariectomy-induced osteoporosis in mice and reverses ligation-induced periodontal alveolar bone loss. Y1693 is applicable to research related to osteoporosis and periodontal diseases.
