  Bazedoxifene-Scaffold-Based Mimetics of Solomonsterols A and B as Novel Pregnane X Receptor Antagonists

  摘要：

  Pregnane X receptor (PXR), a member of the NR1I nuclear receptor family, acts as a xenobiotic sensor and a paramount transcriptional regulator of drug-metabolizing enzymes and transporters. The overexpression of PXR in various cancer cells indicates the importance of PXR as a drug target for countering multidrug resistance in anticancer treatments. We describe the discovery of novel bazedoxifene-scaffold-based PXR antagonists inspired by the marine sulfated steroids solomonsterol A and B as natural leads. A luciferase reporter assay on a PXR-transfected HepG2 cell line identified compounds 19-24 as promising PXR antagonists. Further structure-activity relationship studies of the most active PXR antagonist from the series (compound 20, IC50 = 11 mu M) revealed the importance of hydroxyl groups as hydrogen-bond donors for PXR antagonistic activity. PXR antagonists 20 and 24 (IC50 = 14 mu M), in addition to the downregulation of PXR expression, exhibited inhibition of PXR-induced CYP3A4 expression, which illustrates their potential to suppress PXR-regulated phase-I drug metabolism.
