Novel Peripherally Selective Cannabinoid Receptor 1 Neutral Antagonist Improves Metabolic Dysfunction-Associated Steatotic Liver Disease in Mice

The prevalence of metabolic dysfunction-associated steatotic liver disease (MASLD) is increasing globally. MASLD is characterized by clinically significant liver steatosis, and a subset of patients progress to more severe metabolic-disorder-associated steatohepatitis (MASH) with liver inflammation and fibrosis. Cannabinoid receptor 1 (CB1) antagonism is a proven therapeutic strategy for the treatment of the phenotypes that underlie MASLD, though work on early centrally penetrant compounds largely ceased following adverse psychiatric indications in humans. We present here preclinical testing of a CB1 neutral antagonist,
