Platinum compounds for high-resolution in vivo cancer imaging.

ABSTRACT: Platinum(II) compounds, principally cisplatin and carboplatin, are commonly used front-line cancer therapeutics. Despite their widespread use and continued interest in the development of new derivatives, including nanoformulations with improved properties, it has been difficult to visualize platinum compounds in live subjects, in real time, and with subcellular resolution. Here, we present four novel cisplatin- and carboplatin-derived fluorescent imaging compounds for quantitative intravital cancer imaging. We conjugated 4,4-difluoro-5,7-dimethyl-4-bora-3a,4a-daiza-s-indacene (BODIPY) to Pt(II) complexes to generate derivatives with robust in vivo fluorescence and retained DNA-damaging and cytotoxic properties. We successfully applied these compounds to image pharmacokinetics and tumor upt
