Abstract:
:The development of novel, efficient and nontoxic photosensitizers (PSs) is a challenging task for photodynamic therapy (PDT). In our previous study, corrole had been demonstrated to be a promising PS in PDT for cancer cells. In this paper, a novel electron-deficient flat phosphorus tris(ethoxycarbonyl) corrole (1-P) was synthesized and characterized. In vitro photodynamic activities and toxicity of 1-P in HepG2 xenograft tumours was evaluated by standard assay. The results shown 1-P displayed a potential efficient and low-toxic PS, which suggesting this kind of corrole is a powerful and promising antitumor PS for PDT. In addition, the potential anti-tumour mechanism study of 1-P was also investigated by the apoptosis antibody array, immunohistochemical and western blotting assay (WB) experiments, we found that the PDT activity of 1-P can degrade SIRT1 (an important deacetylase), and activate the Fas signal pathway to inhibit the growth of liver cancer cells.
