3-Mercaptopicolinic Acid, Hydrochloride (3-MPA HCl) is a potent gluconeogenesis inhibitor. In perfused rat livers, gluconeogenesis was inhibited when lactate, pyruvate, or alanine served as substrate, but not with fructose, suggesting phosphoenolpyruvate carboxykinase as the site of inhibition. 3-Mercaptopicolinic Acid, Hydrochloride has been used in studies of DNA and RNA, enzyme kinetics, protein structure, and enzyme inhibition.
