Prostamedix is a 68Ga-labeled ligand of the prostate-specific membrane antigen (PSMA) for Prostate Cancer PET imaging. Because of the increased expression of PSMA in Prostate Cancer and its metastases, Prostamedix was reported to exhibit a favorable lesion-to-background ratio with high detection rates. Further studies evaluating Prostamedix showed substantially higher detection rates in patients with recurrent PC than reported for other imaging modalities, especially at low PSA values. The chelator HBED-CC (N,N'-bis-[2-hydroxy-5-(carboxyethyl)benzyl]ethylenediamine-N,N'-diacetic acid), represents a hitherto rarely used acyclic complexing agent especially allowing efficient radiolabelling with 68Ga even at ambient temperature. By combining HBED-CC with the PSMA inhibitor Glu-urea-Lys, a favorable aromatic part is introduced into the radiotracer which was found to be a necessary requirement for sustainable interaction with the PSMA receptor, putatively with the accessory hydrophobic pocket of the PSMA
