The present invention relates to novel radioactively labeled bioreducible tracers of Formula I useful for detecting hypoxic tumors or ischemic tissue in vivo. In one embodiment, the tracers consist of a 2-nitroimidazole moiety, a triazole, metabolically stable linker with pharmacokinetics enhancing substituents, and a radioisotope. The preferred in vivo imaging modality is positron emission tomography.
本发明涉及一种新型放射性标记的生物还原示踪剂,其化学式为I,可用于体内检测缺氧肿瘤或缺血组织。在其中一种实施方式中,示踪剂由2-硝基咪唑基团、三唑基团、代谢稳定的连接剂和药代动力学增强取代基组成。首选的体内成像模式为正电子发射断层扫描。
