Unveiling Ga(III) phthalocyanine —a different photosensitizer in neuroblastoma cellular model

AbstractPhthalocyanines (Pc) and their metallated derivatives are strongly considered for photodynamic therapy (PDT) possessing unique properties as possible new photosensitizers (PS). We have used toxicological assessments, real ‐time monitoring of cellular impedance, and imagistic measurements for assessing the in vitro dark toxicity and PDT efficacy of Ga(III)‐Pc in SHSy5Y neuroblastoma cells. We have established the non‐toxic concentration range of Ga(III)‐Pc, a compound which shows a high intracellular accumula tion, with perinuclear distribution in confocal microscopy. By choosing Ga(III)Pc non‐toxic dose, we performed in vitro experimental PDT hampering cellular proliferation. Our proposed Ga(III)‐Pc could complete a future PS panel for neuroblastoma alternate therapy.
