Pegylated fluoroalkoxybenzamide compounds which selectively bind Sigma-2 receptors are disclosed. These compounds, when labeled with a positron-emitting radioisotope such as 18F, can be used as radiotracers for medical imaging such as imaging of tumors by positron emission tomography (PET). In addition, these compounds, when labeled with 123I, can be used as radiotracers for imaging of tumors by single photon emission computed tomography (SPECT). Methods for synthesis of these compounds are also disclosed.
本发明公开了聚
乙二醇化氟烷氧基苯酰胺化合物,其选择性地结合Sigma-2受体。这些化合物,当与正电子发射放射性同位素如18F标记时,可用作医学成像的放射性示踪剂,例如通过正电子发射断层扫描(PET)成像肿瘤。此外,这些化合物,当用123I标记时,可用作单光子发射计算机断层扫描(
SPECT)成像肿瘤的放射性示踪剂。本发明还公开了这些化合物的合成方法。
