PF-06835919 is a potent (IC50 = 10 nM KHK-C, 170 nM KHK-A) inhibitor of ketohexokinase (KHK), the first enzyme in the fructose metabolic cascade.1 It displayed high selectivity against other sugar kinases. PF-06835919 prevented hyperinsulinemia, hypertriglyceridemia, and hepatic steatosis in fructose-fed rats.2 The increased tumor proliferation effect of fructose in CaSki cells was inhibited by PF-06835919.3 An interesting new tool to study metabolic and fatty liver diseases.
