Mitochondria-targeting biocompatible fluorescent BODIPY probes.

ABSTRACT: An increase in the mitochondrial membrane potential (MMP) is a characteristic feature of cancer and cardiovascular disease. Therefore, it remains of crucial importance to develop new and improved fluorescent probes that are sensitive to the MMP, to report on mitochondrial health and function. Reported here are the design, synthesis, photophysical properties and biological characterisation of a series of BODIPY dyes, BODIPY-Mito-n, for mitochondria-targeted fluorescence imaging applications. Six BODIPY-Mito-n analogues were synthesised under mild conditions, and displayed excellent fluorescence quantum yields of between 0.59 and 0.72 in aqueous environments at physiological pH (pH = 7.4).
