Summary

We developed a novel ¹⁸⁸Re-labeled PSMA inhibitor using a proprietary N₃S chelator, demonstrating enhanced stability and superior tumor targeting. The optimized agent achieved 100% complete tumor regression with no recurrence in mice, coupled with rapid renal clearance to minimize toxicity. As a generator-produced isotope, ¹⁸⁸Re presents a scalable and cost-effective theranostic platform for advanced cancer treatment, particularly in resource-limited settings
