纳米药物的预定位成像引起了相当大的兴趣,因为它有可能增加成像对比度,同时减少对健康组织的辐射负担。目前,四嗪连接是该策略最快的生物正交反应,因此是体内化学的最新选择。我们最近确定了四嗪在预靶向中的关键特性。我们还开发了一种使用脂肪族亲核取代策略对18 F 标记反应性四嗪进行的方法。在这里,我们结合这些知识并开发了一个18用于预靶向成像的 F 标记四嗪。为了开发这种配体,进行了一项小型 SAR 研究。最有前途的化合物被选择用于标记和随后的正电子发射断层扫描体内成像。以令人满意的产率、摩尔活性和高放射化学纯度实现了放射性标记。[ 18 F] 15显示出良好的药代动力学和显着的靶点与背景比——早在注射后 1 小时。我们相信这种药物可能是转化为临床研究的有希望的候选者。

The present invention relates to novel tetrazine compounds for use in pretargeted in vivo imaging and in therapy and to the precursors of the tetrazine compounds. The compounds are suitable for use in click chemistry, i.e. reactions that join a targeting molecule and a reporter molecule. The compounds comprise a radionuclide of F, I or At and on or more polar groups providing that the compounds can efficiently react with extracellularly located pretargeting vectors and as such used for example for pretargeted cancer diagnostics and cancer therapy.
The invention relates to oxadiazole compounds of formula I. The compounds are useful e.g. in the treatment of autoimmune disorders, such as multiple sclerosis.
