The farnesoid X receptor (FXR) is a promising therapeutic target for nonalcoholic steatohepatitis (NASH) and other bile acid related diseases because it plays a critical role in fibrosis, inflammation and bile acid homeostasis. Obeticholic acid (OCA), a FXR agonist which was synthesized from chenodeoxycholic acid, showed desirable curative effects in clinical trials. However, the pruritus which was the main side effect of OCA limited its further applications in NASH. Although pruritus was also observed in the clinical trials of non-steroidal FXR agonists, the proportion of patients with pruritus was much smaller than that of OCA. Thus, we decided to develop non-steroidal FXR agonists and discovered a series of novel FXR agonists which were synthesized from GW4064 by replacing the stilbene group with ketoxime ether. Encouragingly, in the following biological tests, our target compounds 13j and 13z not only showed potent FXR agonistic activities in vitro, but also effectively promoted the expression of target genes in vivo. More importantly, in the pharmacokinetic experiments, compounds 13j and 13z displayed high liver/blood ratio characteristics which were helpful to reduce the potential side effects which were caused by prolonged systemic activation of FXR. In summary, our compounds were good choices for the development of non-steroidal FXR agonists and were deserved further investigation.

Acetaminophen (APAP) overdose is a leading cause of acute hepatic failure and liver transplantation, while the existing treatments are poorly effective. Therefore, it is necessary to develop effective therapeutic drugs for APAP-induced hepatotoxicity. Farnesoid X receptor (FXR) is a potential target for the treatment of liver disease, and the activation of FXR protects mice against APAP-induced hepatotoxicity. Compound 5, a glycine-conjugated derivative of FXR agonist 4, was designed to extend the chemical space of existing FXR agonists. Molecular modeling study indicated that compound 5 formed hydrogen bond network with key residues of FXR. Moreover, compound 5 (10?mg/kg) revealed better protective effects against APAP-induced hepatotoxicity than parent compound 4 (30?mg/kg). Further mechanical research indicated that compound 5 regulated the expressions of genes related to FXR and oxidative stress. These findings suggest that compound 5 is a promising FXR agonist suitable for further research, and it is the first time to verify that the glycine-conjugated derivative five exerted better protective effects than its parent compound.
