SKF-34288 hydrochloride (3-Mercaptopicolinic acid) is a phosphoenolpyruvate carboxykinase (PEPCK) inhibitor. SKF-34288 hydrochloride is a potent hypoglycemic agent via inhibition of glucose synthesis through the specific inhibition of PEPCK in the gluconeogenesis pathway[1]. SKF-34288 hydrochloride inhibits Asn metabolism and results in an increase in amino acids and amides。
