Summary

Human epidermal growth factor receptor 2 (HER2) is a pivotal biomarker in breast cancer and an established target for positron emission tomography (PET) imaging. Bivalent HER2 probes offer enhanced binding avidity and improved imaging contrast; however, their synthesis remains challenging. Herein, we employed 2-cyanobenzothiazole (CBT)/1,2-aminothiol click chemistry to achieve rapid, metal-free construction of a bivalent HER2-targeted probe efficiently radiolabeled with ⁶⁸Ga, demonstrating its potential for PET imaging applications.
