Effect of 3-mercaptopicolinic acid on gluconeogenesis and gluconeogenic metabolite concentrations in the isolated perfused rat liver.
3-Mercaptopicolinic acid inhibited gluconeogenesis from lactate and alanine, but not dihydroxyacetone, in the perfused rat liver. Hepatic metabolite concentrations suggested that gluconeogenesis was inhibited at phosphoenolpyruvate carboxykinase. The compound is very effective at low concentrations, and seems an ideal agent for use in studying metabolic regulation involving gluconeogenesis and anaplerotic mechanisms.
