Synthesis of Radiolabeled Technetium- and Rhenium-Luteinizing Hormone-Releasing Hormone (Tc/Re-Acdien-LHRH) Conjugates for Targeted Detection of Breast Cancer Cells Overexpressing the LHRH Receptor.

Currently, Re and Tc are widely used radionuclides for cancer detection and diagnosis. New advancements in modalities and targeting strategies of radiopharmaceuticals will provide an opportunity to enhance imagery and detection of smaller colonies of cancer cells while lowering false-positive diagnoses. To understand the chemistry of agents derived from fac-[Tc(CO)(HO)] species, the nonradioactive [Re(CO)(HO)] analogue was used.
