We have investigated halogen-substituted non-steroidal estrogens with selective binding affinity for the estrogen receptor β (ERβ that might be used for imaging the levels of this ER-subtype in breast tumors by positron emission tomography (PET). Based on diarylpropionitrile (DPN, 1a), a compound previously reported that has a 72-fold binding selectivity for ERβ, we developed a series of DPN analogs
我们研究了对雌激素受体 β(ERβ 可用于通过正电子发射断层扫描 (PET) 对这种 ER 亚型水平进行成像的雌激素受体 β(ERβ)具有选择性结合亲和力的卤素取代的非甾体雌激素。基于二芳基丙腈(DPN) , 1a ),一种先前报道的对 ERβ 具有 72 倍结合选择性的化合物,我们开发了一系列具有甲基、羟基和卤素取代基(包括氟乙基和氟丙基)的 DPN 类似物。3H]雌二醇,所有这些 DPN 类似物都显示出高 ERβ/ERα 选择性;虽然选择性各不相同,但在某些情况下达到近 300 倍(RBA:ERα,0.023%;ERβ,6.25%)。然而,绝对 ERβ 结合亲和力不足以值得进一步考虑将这些配体开发为 PET 成像剂。
