Abstract
There are no known approved pharmacotherapies for non-alcoholic fatty liver disease (NAFLD) in the clinical setting. Although studies have provided substantial evidence that geranylgeranyl diphosphate synthase (GGPPS) is a potential therapeutic target for the treatment of NAFLD corresponding drug screening is rare. A GGPPS-targeted inhibitor is identified using a structure-based virtual small molecule screening method. The interaction of 4-AZ and GGPPS is detected by microscale thermophoresis. 4-AZ degradation of GGPPS by the ubiquitin-proteasome pathway is detected by western blotting. The anti-steatotic effect of 4-AZ in vivo is detected by CT. Lipid-related gene detection is detected by real-time PCR both in primary hepatocytes and mice. The compound inhibits the accumulation of lipids in primary hepatocytes and decreases lipogenic gene expression through GGPPS. Pharmacological studies show that 4-AZ can attenuate hepatic steatosis and improve liver injury in high-fat diet-induced mice. This data provides a novel application of 4-AZ NAFLD therapy, proving that the inhibition of GGPPS is a novel strategy for the treatment of NAFLD.
