Bile acids exert genomic and nongenomic effects by interacting with membrane G-protein-coupled receptors, including the bile acid receptor GP-BAR1, and nuclear receptors, such as the farnesoid X receptor (FXR). These receptors regulate overlapping metabolic functions; thus, GP-BAR1/FXR dual agonists, by enhancing the biological response, represent an innovative strategy for the treatment of enteroendocrine disorders. Here, we report the design, total synthesis, and in vitro/in vivo pharmacological evaluation of a new generation of dual bile acid receptor agonists, with the most potent compound, 19, showing promising pharmacological profiles. We show that compound 19 activates GP-BAR1, FXR, and FXR regulated genes in the liver, increases the intracellular concentration of cAMP, and stimulates the release of the potent insulinotropic hormone GLP-1, resulting in a promising drug candidate for the treatment of metabolic disorders. We also elucidate the binding mode of the most potent dual agonists in the two receptors through a series of computations providing the molecular basis for dual GP-BAR1/FXR agonism.

Nuclear and G-protein coupled receptors are considered major targets for drug discovery. FXR and GP-BAR1, two bile acid-activated receptors, have gained increasing consideration as druggable receptors. Because endogenous bile acids often target both receptor families, the development of selective ligands has been proven difficult, exposing patients to side effects linked to an unwanted activation of one of the two receptors. In the present study, we describe a novel library of semisynthetic bile acid derivatives obtained by modifications on the cholane scaffold. The pharmacological characterization of this library led to the discovery of 7α-hydroxy-5β-cholan-24-sulfate (7), 6β-ethyl-3α,7β-dihydroxy-5β-cholan-24-ol (EUDCOH, 26), and 6α-ethyl-3α, 7α-dihydroxy-24-nor-5β-cholan-23-ol (NorECDCOH, 30) as novel ligands for FXR and GP-BAR1 that might hold utility in the treatment of FXR and GP-BAR1 mediated disorders.

Within our efforts in the discovery of novel potent and selective ligands for the FXR receptor, 23-N-(carbocinnamyloxy)-3α,7α-dihydroxy- 6α-ethyl-24-nor-5β-cholan-23-amine was synthesized and evaluated for its ability to activate and modulate the biological response of the receptor. Alphascreen and RT-PCR revealed that the 6α-ethyl-24-norcholanyl-23-amine derivate behaves as full FXR agonist endowed with high binding affinity and efficacy, representing a promising lead candidate for further optimization. In addition, docking studies provide new insights into the molecular basis governing the partial and full agonist activity at FXR.
