Development of cyclopeptide inhibitors specifically disrupting FXR-coactivator interaction in the intestine as a novel therapeutic strategy for MASH.
Intestinal farnesoid X receptor (FXR) antagonists have been proven to be efficacious in ameliorating metabolic diseases, particularly for the treatment of metabolic dysfunction-associated steatohepatitis (MASH). All the reported FXR antagonists target to the ligand-binding pocket (LBP) of the receptor, whereas antagonist acting on the non-LBP site of nuclear receptor (NR) is conceived as a promising strategy to discover novel FXR antagonist. Here, we have postulated the hypothesis of antagonizing FXR by disrupting the interaction between FXR and coactivators, and have successfully developed a series of macrocyclic peptides as FXR antagonists based on this premise. The cyclopeptide DC646 not only exhibits potent inhibitory activity of FXR, but also demonstrates a high degree of selectivity towards other NRs. Moreover, cyclopeptide DC646 has high potential therapeutic benefit for the treatment of MASH in an intestinal FXR-dependent manner, along with a commendable safety profile. Mechanistically, distinct from other known FXR antagonists, cyclopeptide DC646 specifically binds to the coactivator binding site of FXR, which can block the coactivator recruitment, reducing the circulation of intestine-derived ceramides to the liver, and promoting the release of glucagon-like peptide-1 (GLP-1). Overall, we identify a novel cyclopeptide that targets FXR-coactivator interaction, paving the way for a new approach to treating MASH with FXR antagonists.
