  Ursodeoxycholic Acid Amides As Novel Glucocorticoid Receptor Modulators

  摘要：

  Ursodeoxycholic acid (UDCA) is used for the treatment of hepatic inflammatory diseases Recent studies have shown that UDCA's biological effects are partly glucocorticoid receptor (GR) mediated UDCA derivatives were synthesized and screened for ability to induce GR translocation in a high content analysis assay using the esophageal cancel SKGT-4 cell line UDCA derivatives induced GR translocation in a time dependent manner with equal efficacy to that of dexamethasone (Dex) and with greatly increased potency relative to UDCA The cyclopropylamide la suppressed TNF-alpha Induced NF-kappa B activity and it induced GRE transactivation la was unable to displace Dex from the GR ligand binding domain (LBD) in a competition experiment but was capable of coactivator recruitment in a time-resolved fluorescence energy transfer assay (TR-FRET) This represents a novel mechanism of action for a GR modulator These derivatives could result in a new class of GR modulators
