Ac-KQKLR-AMC (Cathepsin S substrate) is a biological active peptide. (Cathepsins are a class of globular lysosomal proteases, playing a vital role in mammalian cellular turnover. They degrade polypeptides and are distinguished by their substrate specificities. Cathepsin S is a cysteine proteinase involved in the pathogenesis of autoimmune diseases, atherosclerosis, cancer, obesity and related diseases.This peptide is a cathepsin S substrate fluorescently labeled with AMC (Ex/Em=354 nm/442 nm). It can be used to measure cathepsin S activity.)

Reptoside, which can be extracted from the roots and above-ground parts of Cortex Eucommiae and Ajuga chamaepitys (L.) Schreb, is one of the active cyclic enol ether terpene glycosides of Cortex Eucommiae for the treatment of osteoporosis.
