Starting from a weak FXR/PPAR agonist, we have developed selectiveFXR activators and antagonists with nanomolar to low-micromolar potencies and binding affinities. The new FXRligand chemotype modulates the FXR activity in the native cellular setting, is endowed with favorable metabolic stability, and lacks cytotoxicity. It valuably expands the collection of FXRmodulators as a new scaffold for FXR-targeted
