Tropifexor is an investigational drug that acts as an agonist of the farnesoid X receptor (FXR). It was discovered by researchers from Novartis and Genomics Institute of the Novartis Research Foundation. Its synthesis and pharmacological properties were published in 2017.[1] It was developed for the treatment of cholestatic liver diseases and nonalcoholic steatohepatitis (NASH). In combination with cenicriviroc, a CCR2 and CCR5 receptor inhibitor, it is undergoing a phase II clinical trial for NASH and liver fibrosis.[2]

Rats treated orally with tropifexor (0.03 to 1 mg/kg) showed an upregulation of the FXR target genes, BSEP and SHP, and a down-regulation of CYP8B1. Its EC50 for FXR is between 0.2 and 0.26 nM depending on the biochemical assay.
The patent that covers tropifexor and related compounds was published in 2010.[3]
