Overview

**99mTc(CO)3BPS-imidazole-EUK** is an experimental **PSMA-targeted radiopharmaceutical imaging agent** for prostate cancer. It consists of a technetium-99m tricarbonyl complex coordinated by a bathophenanthroline disulfonate and imidazole-based chelation system attached to the **Glu-Urea-Lys** PSMA-binding pharmacophore. The agent is designed to bind **prostate-specific membrane antigen** on prostate cancer cells and enable nuclear imaging, with reported preclinical binding affinity in LNCaP cells, intracellular uptake, in vitro stability, and mouse biodistribution showing lower kidney uptake than a comparator 99mTc-HYNIC-PSMA tracer. Based on the cited publication, it appears to be an academic-stage preclinical imaging candidate rather than a commercial product, with potential future adaptation of the same chelation concept to rhenium-labeled diagnostic or therapeutic applications.
