  Novel 7α-alkoxy-17α-(4′-halophenylethynyl)estradiols as potential SPECT/PET imaging agents for estrogen receptor expressing tumours: Synthesis and binding affinity evaluation

  摘要：

  In order to develop potential radiolabelled probes for imaging estrogen receptor (ER) positive tumours, we have synthesized and characterized a series of novel 7 alpha-alkoxy-17 alpha-(4'-iodophenylethynyl)estra-1,3,5(10)-triene-3,17 beta-diols and 7 alpha-alkoxy-17 alpha-(4'-fluorophenylethynyl)estra-1,3,5(10)-triene-3,17 beta-diols. The fluoro-substituted compounds showed a higher ER binding affinity than the corresponding iodo-derivatives, where 7 alpha-methoxy- and 17 alpha-(4'-fluorophenylethynyl)estra-1,3,5(10)-triene-3,17 beta-diol showed the highest ER binding affinities (RBA = 80.9% and 78.9%, respectively), among the halophenylethynyl compounds studied and should be further explored as potential PET biomarkers for imaging of ER expressing tumours.
