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.
本发明涉及用于体内预靶向成像和治疗的新型四嗪化合物以及四嗪化合物的前体。这些化合物适用于点击
化学反应,即连接靶向分子和报告分子的反应。这些化合物由 F、I 或 At 放射性核素和一个或多个极性基团组成,可与位于细胞外的预靶向载体有效反应,因此可用于癌症预靶向诊断和癌症治疗等。
