A new silicon phthalocyanine with piperazine-furan ring and its quaternized form were synthesized. All compounds were analyzed by spectroscopic techniques (FT-IR, 1H-NMR, MS, and UV-vis), and the absorbance characteristics of silicon phthalocyanines were evaluated with the expected strong typical absorption bands in the far-red spectrum. The cytotoxic effects of these phthalocyanines induced by photodynamic therapy (PDT) were determined in a dose-dependent manner. Following cytotoxicity anal., flow cytometric research of cell death was performed. The formation of reactive oxygen species (ROS) was determined by confocal microscopy. High levels of cytotoxicity and decreased viable cell population have been detected in cancer cells after treatment. In addition, ROS formation was observed in PDT treated cancer cells. However, low levels of cell death and ROS formation were observed in non-tumorigenic cells. According to western blot data, PDT-mediated treatment was found to provide different expression patterns of the cleaved PARP1 protein. The presented study demonstrates that PDT-mediated treatment of newly synthesized phthalocyanines has significant anti-cancer effects on breast cancer cells and may induce different cell death pathways.
