Platinum(II) compounds, principally cisplatin and carboplatin, are commonly used front-line cancer therapeutics. Despite widespread use and the interest of developing new derivatives, including nanoformulations with improved properties, it has been difficult to visualize Pt 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 conjugate boron dipyromethene FL (BODIPY-FL) to PtII complexes for robust in vivo fluorescence, and show retained DNA-damaging and cytotoxic properties. We image pharmacokinetics and tumor uptake in a xenograft cancer mouse model. Finally, we present a genetic reporter of single-cell DNA damage for in vivo imaging, and simultaneously monitor Pt drug accumulation and resultant DNA damage in individual tumor cells, at subcellular resolution, and in real-time in a live animal model of cancer.
