title: Zinc-(II) 2,9,16,23-tetrakis (methoxy) phthalocyanine: potential photosensitizer for use in photodynamic therapy in vitro.
abstract: Photodynamic therapy (PDT) is an innovative treatment for several types of malignant and non-malignant disease. In the present study, ZnPcOCH(3) was investigated on a human larynx-carcinoma cell line (Hep-2) for its use in PDT. This drug exhibited favourable properties as a photosensitizer in vitro because ZnPcOCH(3) is able to penetrate efficiently in the cytoplasm of cultured cancer cells and is partially localized in lysosomes. The results show that ZnPcOCH(3)-PDT-induced apoptosis by caspase dependent pathway. The new compound shows a good photosensitizing efficiency in vitro on Hep-2 cells, encouraging further in vivo studies.
