| Summary: | Nonalcoholic steatohepatitis (NASH) has become a leading cause of liver fibrosis and hepatocellular carcinoma; however, there are no efficient drugs for NASH therapy. Acetyl-CoA carboxylase (ACC) is a crucial enzyme regulating lipid metabolism that is considered as a potential target for NASH treatment. Allosteric inhibitors target nonfunctional sites, which tend to be highly variable in protein families; thus, allosteric inhibitors are explored as an important source of drug candidates. Herein, several hotspot residues are initially identified by utilizing molecular dynamic simulation, MM-GBSA calculation, and alanine mutation. Then, focusing on the interaction with hotspot residues, several cyclobutane-based ACC allosteric inhibitors are designed, synthesized, and biologically evaluated. Among them, <b>B1</b> demonstrates potent ACC inhibitory activity <i>in vitro</i>, a higher distribution in liver than in other tissues, and a potent therapeutic effect for NASH <i>in vivo</i>, making it a promising candidate for the treatment of NASH. |
