Biotin-NH-PSMA-617 

Biotin-NH-PSMA-617 is a biotin-tagged PSMA-617. PSMA-617 is a small molecule targeting the prostate-specific membrane antigen (PSMA), which is directly expressed by the tumor cells ^[1].

PSMA-617 is a PSMA ligand. PSMA-617 shows a significantly improved binding affinity to PSMA as well as a highly efficient internalization into PCa cells. PSMA-617 can be labeled with ⁶⁸Ga, ¹⁷⁷Lu, ¹¹¹In, and ⁹⁰Y and, therefore, be used for PET-imaging as well as for radioligand-based therapy^[1].
