以Cyclofenil为原料, 合成得到一系列氟乙氧基衍生物. 通过受体结合实验, 筛选得到一个对雌激素受体(ER)具有高特异性和高相对亲和力(RBA)的化合物Penta-Cyclofenil-FEt. 通过实验的优化设计, 合成得到相应的氟标记前体, 产物通过IR, UV, 1H NMR, 19F NMR或ESI-HRMS进行了表征. 在冷试条件下, 得到了冷氟取代参比化合物. 在热试验条件下, 得到F-18标记产物. 此类非甾体雌激素受体分子探针的合成, 为PET (positron emission tomography)显像雌激素受体β从而评估乳腺癌的恶化程度奠定了基础.

Starting from cyclofenil, a serial of cyclofenil-FEt derivatives were prepared. Generally speaking pentacyclofenil-FEt has greater relative binding affinity (RBA) to estradiol receptors than that of estradiol. The precursor compounds were synthesized for potential radioactive imaging agents, and their structures were characterized by ultraviolet, infrared, 1H NMR, 19F NMR, and ESI-HRMS techniques. The non- radioactive/radioactive compounds were synthesized. The study provides a useful assessment of the stage of the breast cancer by imaging ERβ with the PET (positron emission tomography) imaging.

Key words: cyclofenil, fluoroethyl, breast cancer, binding affinity, PET imaging
