Disease
[F16P1_HUMAN] Defects in FBP1 are the cause of fructose-1,6-bisphosphatase deficiency (FBPD) [MIM:229700]. FBPD is inherited as an autosomal recessive disorder mainly in the liver and causes life-threatening episodes of hypoglycemia and metabolic acidosis (lactacidemia) in newborn infants or young children.[1] [2]

Publication Abstract from PubMed
Human fructose-1,6-bisphosphatase (FBPase, EC 3.1.3.11) is a key gluconeogenic enzyme, responsible for the hydrolysis of fructose-1,6-bisphosphate to fructose-6-phosphate, and thus presents an opportunity for the development of novel therapeutics focused on lowering the hepatic glucose production in type 2 diabetics. In its active form FBPase exists as a homotetramer and is allosterically regulated by AMP. In an HTS campaign aromatic sulfonylureas have been identified as FBPase inhibitors mimicking AMP. By bridging two adjacent allosteric binding sites using two aromatic sulfonylureas as anchor units and covalently linking them, it was possible to obtain dual binding AMP site inhibitors that exhibit a strong inhibitory effect.
Allosteric FBPase inhibitors gain 10(5) times in potency when simultaneously binding two neighboring AMP sites.,Hebeisen P, Kuhn B, Kohler P, Gubler M, Huber W, Kitas E, Schott B, Benz J, Joseph C, Ruf A Bioorg Med Chem Lett. 2008 Aug 15;18(16):4708-12. Epub 2008 Jul 5. PMID:18650089[3]
