An efficient method to incorporate the fluorine-18 radionuclide in 2-nitropurine-based nucleosides was developed. The nucleophilic radiofluorination of the labeling precursor with [(18)F]KF under aminopolyether-mediated conditions (Kryptofix 2.2.2/K2CO3) followed by deprotection was straightforward and, after formulation, gave 2-[(18)F]fluoroadenosine, ready for injection with a radiochemical yield
开发了一种将氟18放射性核素掺入基于2-硝基嘌呤的核苷中的有效方法。在氨基聚醚介导的条件下(Kryptofix 2.2.2 / K2CO3)用[(18)F] KF对标记前体进行亲核放射性氟化,然后进行脱保护是很简单的,配制后得到2-[((18)F]氟代腺苷)用于注射的放射化学产率为45 +/- 5%,放射化学纯度> 98%,比放射性最高为148 GBq / mumol。报道了对啮齿动物的微正电子发射断层扫描成像和生物分布研究。
