Metal/radiometal-labeled PSMA inhibitors for PSMA-targeted imaging and radiotherapy

摘要

Low-molecular weight gadolinium (Gd)-based MR contrast agents for PSMA- specific Ti-weighted MR imaging are disclosed. The (Gd)-based MR contrast agents exhibit high binding affinity for PSMA and exhibit specific Ti contrast enhancement at PSMA+ cells. The PSMA-targeted Gd-based MR contrast agents can be used for PSMA- targeted imaging in vivo. 86Y-labeled PSMA-binding ureas also are provided, wherein the PSMA-binding ureas also are suitable for use with other radiotherapeutics.
