Description

technical field [0001] The present invention relates to FXR receptor agonists, their pharmaceutically acceptable salts, their esters and their stereoisomers, pharmaceutical preparations containing these compounds, and the compounds, their pharmaceutically acceptable salts, their esters and their stereoisomers Use of the isomer in the preparation of medicines for treating and / or preventing non-alcoholic fatty liver, primary biliary cirrhosis, lipid metabolism disorders, diabetic complications, malignant tumors and other related diseases mediated by FXR receptors . Background technique [0002] The FXR receptor (farnesoid X receptor) belongs to the nuclear receptor family of ligand-activated transcription factors and has a typical nuclear receptor structure, namely, a highly conserved DNA-binding domain (DBD) at the amino-terminus and a ligand-binding domain at the carboxyl-terminus. (LBD), amino-terminal ligand-independent transcriptional activation domain (AF1), carboxy-ter...
