General description

Cathepsin L Inhibitor is a histone H3-processing enzyme. It is important for maintaining epidermal homeostasis, regular hair follicle morphogenesis and cycling. Cathepsin L is involved in protein degradation. It might regulate normal functioning of the immune system. Cathepsin L regulates the death of macrophages, necrotic core formation and development of atherosclerotic plaque instability.

Application

Cathepsin L is a lysosomal cysteine proteinase that metabolizes collagens and elastins. The roles and activity of Cathepsin L can be studied with the aid of peptide inhibitors such as the pentapeptide amide RKLLW-NH2 (Arg-Lys-Leu-Leu-Trp-NH2).

From their discovery in the first half of the 20th century, lysosomal cysteine proteases have come a long way: from being the enzymes non-selectively degrading proteins in lysosomes to being those responsible for a number of important cellular processes. Some

By screening a combinatorial pentapeptide amide collection in an inhibition assay, we systematically evaluated the potential of 19 proteinogenic amino acids and seven nonproteinogenic amino acids to serve as building blocks for inhibitors of human cathepsin L. Particularly efficient were
