PKCζ Activator

Spisulosine (ES-285) is an antiproliferative (antitumoral) compound of marine origin. Spisulosine inhibits the growth of the prostate PC-3 and LNCaP cells through intracellular ceramide accumulation and PKCζ activation. Spisulosine induces apoptosis in PC-3 and LNCaP cells.

Cathepsin G is a pH-dependent serine protease. Cathepsin G hydrolyzes diverse synthetic and protein substrates and remodels extracellular matrix. Cathepsin G exerts immunomodulatory effects via recruiting phagocytes, enhancing T cell motility, activating ERK1/2 and p38 MAPK signaling, and mediating PKCζ membrane translocation. Cathepsin G regulates inflammatory responses by cleaving inflammatory mediators. Cathepsin G participates in vascular regulation by converting angiotensin I to angiotensin II. Cathepsin G induces PAR4-dependent platelet activation, facilitates platelet-neutrophil aggregation, and mediates VITT-related NETosis, thrombus formation. Cathepsin G can be used for the research of immune thrombotic thrombocytopenia, cardiovascular disease, and select autoimmune and inflammatory diseases.
