摘要
Novel enantiomers and diastereoisomers structurally related to σ ligand (+)-MR200 were synthesized to improve σ(1)/σ(2) subtype selectivity. The selective σ(1) ligand (-)-8 showed an antagonist profile determined by phenytoin differential modulation of binding affinity in vitro, confirmed in vivo by an increase of κ opioid analgesia. The σ(2) ligand (-)-9 displayed agonist properties in an in vitro isolated organ bath assay and antiproliferative effects on LNCaP and PC3 prostate cancer cell lines.
