A simple halogenated derivative of dopamine, 6-iododopamine (1), has been synthesized using two different methods. These synthetic sequences have been applied to the radiolabeling of 1 with carbon-11, iodine-131, and iodine-123. The tissue distribution of 1 in mice, dogs, and rats was determined. The ratio of radioactivity (%/g) in the adrenal medulla-kidney in dogs increases from 3.45 at 2 h postinjection
已使用两种不同方法合成了一种简单的
多巴胺卤代衍
生物6-
碘多巴胺(1)。这些合成序列已应用于碳11,
碘131和
碘123的放射性标记。确定了在小鼠,狗和大鼠中1的组织分布。犬肾上腺髓质-肾脏的放射性比(%/ g)从注射后2 h的3.45增加到注射后24 h的33.3。小鼠,狗和大鼠中的甲状腺摄取显示1的体内
碘化作用不明显。
