Mitochondria-Localized Fluorescent BODIPY-Platinum Conjugate.
A convenient synthesis of a BODIPY (1,3,5,7-tetramethyl-8-(4-pyridyl)-4,4'-difluoroboradiazaindacene) labeled platinum compound (BODIPY-Pt) was developed by direct conjugation of cisplatin with the pyridine group of BODIPY. The membrane permeability and selective uptake of BODIPY-Pt in the mitochondria was studied using confocal laser scanning microscopy (CLSM). The fluorescent BODIPY-Pt conjugate showed high cellular proliferation inhibition against human cervical carcinoma (HeLa) and human breast cancer (MCF-7) cells, with half maximal inhibitory concentrations (IC50) of 27.37 and 12.14 μM, respectively. This work highlights the potential of using BODIPY labeled Pt compounds to realize the visualization of Pt distribution in living cells.
