Investigation around the Oxadiazole Core in the Discovery of a New Chemotype of Potent and Selective FXR Antagonists.

ABSTRACT: Recent findings have shown that Farnesoid X Receptor (FXR) antagonists might be useful in the treatment of cholestasis and related metabolic disorders. In this paper, we report the discovery of a new chemotype of FXR antagonists featured by a 3,5-disubstituted oxadiazole core. In total, 35 new derivatives were designed and synthesized, and notably, compounds 3f and 13, containing a piperidine ring, displayed the best antagonistic activity against FXR with promising cellular potency (IC₅₀ = 0.58 ± 0.27 and 0.127 ± 0.02 μM, respectively). The excellent pharmacokinetic properties make compound 3f the most promising lead identified in this study.
