Goodyeroside A is a glycoside compound derived from the plant Goodyera that exhibits significant hepatoprotective activity. It can inhibit liver damage induced by carbon tetrachloride in primary cultured rat hepatocytes.

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.)

8-Bromoguanosine is a brominated derivative of guanosine. It is activate lymphocytes through an intracellular mechanism to exert immunostimulatory effects.
