3- Aminopicolinate , a hyperglycemic agent that activates purified phosphoenolpyruvate carboxykinase in the presence of Fe2+, inhibits glucose synthesis from lactate, pyruvate, asparagine, monomethyl succinate, or glutamine but does not affect that from fructose, dihydroxyacetone, sorbitol, or glycerol in hepatocytes isolated from rats fasted for 24 h. Lactate production from monomethyl succinate by hepatocytes is also inhibited by 3- aminopicolinate . This compound elevates the concentrations of pyruvate, malate, and aspartate but decreases that of phosphoenolpyruvate in hepatocytes incubated with lactate plus pyruvate. In rats, the ability of 3- aminopicolinate to elevate blood glucose concentration is unimpaired by renalectomy . The drug does not significantly affect glycemia in functionally hepatectomized rats but accelerates blood lactate and pyruvate accumulation to higher maximum concentrations even when kidney function is also ablated. It is concluded that 3- aminopicolinate inhibits phosphoenolpyruvate carboxykinase in hepatocytes, that the reported stimulation of renal glutaminase and glutamine gluconeogenesis by this compound does not contribute significantly to its hyperglycemic property, and that the drug increases gluconeogenic substrate supply from peripheral tissues.
