building block, bearing an alkyl linker with a terminal chloride and an ester group is described. This building block was modified by nucleophilic substitution, leading to two new fac‐[Re(CO)3]+ containing derivatives of known drug candidates for brain imaging and multi‐drug resistance in cancer in as few as two steps. Furthermore, the chloride was replaced by an azide, which was subsequently coupled to
描述了双官能团基于环戊二烯的结构单元的合成,该结构单元带有带有末端氯化物和酯基的烷基连接基。通过亲核取代修饰了该结构单元,仅需两个步骤即可生成两个新的fac- [Re(CO)3 ] +,这些衍生物包含已知的候选药物衍生物,可用于脑成像和癌症的多药耐药性。此外,氯化物被叠氮化物替代,随后与作为模型炔烃的苯乙炔偶联,证明了其在进行Click型反应中的多功能性。所得三唑标记为99mTc产生相应的钢琴凳复合物,放射化学纯度为86%。通过与Re同源物共同注射来确认身份。
