Abstract
Following previous studies where we developed some high performance porphyrin derivatives for photodynamic therapy demonstrating their activity in different cell lines, we now extend our attention to CRL1472 bladder cancer line. In this work the phototoxicity of several diaryl and tetraarylporphyrins with different structures were evaluated with different incubation times. The phototoxicity observed was not directly related to the concentration of photosensitizer inside cells. Uptake studies demonstrate that the brominated derivative 2 which despite the most efficient photosensitizer presents a poor tendency to enter into cells.
