Photodynamic effect of 5,10,15,20-tetrakis(4-methoxyphenyl) porphine (TMP) on Hep-2 cell lines

The photodynamic effect of 5,10,15,20-tetrakis(4-methoxyphenyl)porphine (TMP) on Hep-2 cell line is reported. The incorporation of TMP was analyzed at different times and photosensitizer concentrations. The irradiation of cell cultures produces cell mortality, while no toxicity was observed in dark condition.
