Excessive fructose consumption is a significant driver of metabolic disorders, including obesity, diabetes, non-alcoholic fatty liver disease and steatohepatitis primarily by promoting insulin resistance fat accumulation. Ketohexokinase C (KHK-C), pivotal enzyme in metabolism, catalyzes the phosphorylation to fructose-1-phosphate, initiating cascade downstream processes. In contrast glucose KHK-C lacks negative feedback regulation, allowing continuous fructose, which leads heightened levels glucose, glycogen, triglycerides bloodstream liver. While targeting offers promising therapeutic avenue, no drugs have yet been approved for clinical use. Pfizer's PF-06835919 has progressed phase II trials, demonstrating reduction improved sensitivity, while Eli Lilly's LY-3522348 also shows potential.
