Study on the Synthesis and in vitro Photodynamic Anti-cancer Activity of Tetra（trifluoroethoxy） Germanium Phthalocyanine①

The synthesis and in vitro photodynamic anticancer activity of a new photosensitizer, tetra(trifluoroethoxy) germanium phthalocyanine(GePcF), were studied. GePcF was characterized by UV-Vis, IR, MS and elemental analysis. The in vitro photodynamic activity of GePcF was studied by MTT. IC50 of GePcF for SW480 cells of human colonic adenocarcinoma and HeLa cells of cervical cancer were 36.53 and 45.78 μmol/L, respectively. GePcF as a photosensitizer may be used to treat cancers due to its photodynamic anticancer activity.
