چکیده انگلیسی
Effect of the iron chelator deferoxamine (DF) on the production of endogenous porphyrins was studied in adenocarcinoma WiDr cells and erythroid K562 cells in vitro. Porphyrin fluorescence was observed in the cells in vitro incubated with DF. The fluorescence spectra recorded in the cells were similar to that of protoporphyrin IX (PpIX). The amount of PpIX generated by DF was around 5% of the ALA effect. Around 90% of the WiDr cells incubated in vitro with DF (0.5Â mM, 24Â h) and then exposed to light (400-460Â nm, 20Â min) were photodynamically inactivated. In conclusion, the present study describes a novel approach of using iron chelating agents without 5-aminolevulinic acid (ALA) to photosensitize cancer cells.
