Two N,N-bis-chloroethylamino-phenylsulfoxides have been synthesized and radiolabelled with F-18 via halogen exchange. The radiolabelling of both compounds proceeds smoothly with K[18F]F-kryptofix 2.2.2 complex at 100 °C in DMSO. Decay-corrected radiochemical yields were 25–35% for [18F]12 (SO201) and 35–45% for [18F]11 (SO101), with an average specific activity of 1.8 Ci/µmol. Both compounds remained 80% intact in plasma over a period of 2 h. In vivo binding in a stroke model indicates that both markers are selectively retained in hypoxic tissue.

我们合成了两种 N,N-双氯乙基氨基苯基硫氧化物,并通过卤素交换用 F-18 进行了放射性标记。在 100 °C 的二甲基亚砜中,这两种化合物与 K[18F]F-kryptofix 2.2.2 复合物一起顺利进行放射性标记。衰变校正放射化学产率为:[18F]12 (SO201) 25-35%,[18F]11 (SO101)35-45%,平均比活度为 1.8 Ci/µmol。在中风模型中的体内结合表明,这两种标记物都能选择性地保留在缺氧组织中。Copyright © 2006 John Wiley & Sons, Ltd. All Rights Reserved.
