with FXR, a series of 3-aryl heterocyclic isoxazole analogs were designed and synthesized. N-Oxidepyridine analog (7b) was identified as a promising FXR agonist with potent binding affinity and good efficacy, supporting our hypothesis that through an additional hydrogenbond interaction between the pyridine substituent of isoxazole analogs and Tyr373 and Ser336 of FXR, binding affinity and functional
