ethyl chloroformate with amino compounds has been evaluated as a simple route to carbon-11 labeling of steroid hormone-receptor-based imaging agents. Both a 17 beta-amino analogue of estradiol and an aminoethyl derivative of the nonsteroidal estrogen hexestrol with potential affinity for the estrogen receptor were studied. The unlabeled carbamate derivatives of the amino estrogens were prepared by standard
氯甲酸乙酯与氨基化合物的反应已被评估为一种简单的途径,可对基于类固醇激素受体的显像剂进行碳11标记。研究了雌二醇的17β-氨基类似物和非甾体雌激素己雌醇的氨乙基衍生物对雌激素受体的潜在亲和力。通过标准方法制备未标记的氨基雌激素的氨基甲酸酯衍生物,并由[11C]乙基氯甲酸酯合成11C标记的类似物,该产物是用[11C]光气吹扫乙醇而生成的。两种氨基甲酸酯均显示出对雌激素受体的体外结合亲和力弱,并且只有11C标记的己烯雌酚在未成熟大鼠中显示出少量但明显的雌激素反应性子宫摄取。
