Novel Cyanoarylporphyrazines with Triazole Groups at the Macrocycle Periphery as Potential Sensibilizers of Photodynamic Therapy and Optical Probes of Intracellular Viscosity

Novel fluorescent dyes of the cyanoarylporphyrazine series containing peripheral triazole groups have been synthesized. Their photophysical properties and the local viscosity effect on the fluorescence have been studied. The experiments with cell cultures have revealed rapid accumulation of the dyes in the cells cytoplasm. Photo- and dark cytotoxicity of the compounds have been evaluated by means of the MTT test.
