Overview

68Ga-Glu-urea-Lys-HBED-CC-FITC is a dual-labeled small molecule radiopharmaceutical and fluorescent probe designed for the management of prostate cancer. It is a derivative of the established PET tracer 68Ga-PSMA-11, utilizing a glutamate-urea-lysine (EuK) pharmacophore to target the Prostate-Specific Membrane Antigen (PSMA) with high affinity (IC50 of 11.14 nM). The molecule incorporates a Gallium-68 isotope via an HBED-CC chelator for preoperative positron emission tomography (PET) imaging and is conjugated to fluorescein isothiocyanate (FITC) to provide intraoperative fluorescence guidance. This hybrid approach allows for the preoperative identification of tumor lesions and subsequent real-time visual guidance during surgical resection. Preclinical studies have demonstrated high PSMA-specific internalization and significant tumor uptake, supporting its potential for improving surgical outcomes in prostate cancer patients.
