  Synthesis of C-6 fluoroandrogens: Evaluation of ligands for tumor receptor imaging

  摘要：

  Seven androgens, substituted with fluorine at C-6, were prepared as potential imaging agents for androgen receptor-positive prostate tumors and were evaluated in vitro in terms of their lipophilicity and their relative binding affinities (RBA, relative to R 1881 = 100) for the androgen receptor and for sex steroid binding protein. Introduction of a fluorine atom into the C-6 position of an androgen generally decreases binding affinity to the androgen receptor, except in the two cases: 6 alpha-fluoro-19-nor-testosterone (RBA = 41.6 versus 30.6 for the unsubstituted steroid) and 6 alpha-fluoro-19-nor-testosterone (RBA = 8.9 versus 6.6). Receptor binding of the C-6 fluoro-androgens is also stereospecific, showing higher binding affinities for the alpha-epimers compared to the corresponding beta-epimers (4:1-15:1). Binding affinity to sex steroid binding protein is the lowest with 19-nor-testosterone, which is also the least lipophilic androgen studied. Based on the binding properties of compounds in this series, 6 alpha-fluoro-19-nor-testosterone appears to have the most promise as a turner imaging agent.

  N-Fluoropyridinium salts provide a new system of fluorinating agents by which a wide range of nucleophilic substrates differing in reactivity can be fluorinated due to the varying degree of fluorinating power and also fluorinated very selectively through structural alteration. The scope of selective fluorination should be broadened considerably on the basis of the present results. The N-fluoropyridinium

  Fluorine and sodium trifluoroacetate react at −75° to produce a variety of fluoroxy-compounds. Although it is possible to direct the reaction towards the formation of CF3COOF or CF3CF2OF, mixtures may be used when only the electrophilic fluorine has to be attached to the molecule of interest. Such is the case of the reaction of enol-acetates with the mixture of the fluoroxy reagents. A wide variety

  氟和三氟乙酸钠在-75°下反应生成各种氟代化合物。尽管可以将反应引导至CF 3 COOF或CF 3 CF 2 OF的形成，但是当仅亲电氟必须连接到目标分子上时，可以使用混合物。烯醇-乙酸酯与氟代试剂混合物的反应就是这种情况。测试了多种化合物，包括类固醇和含有各种官能团。在大多数情况下，以良好至非常高的收率获得了所需的α-氟代酮。新的含氟化合物是编号为和的化合物。
