For the first time, the behaviour of tobacco cell suspensions submitted to four porphyrins was described. The potential killer effect of these photosensitizers on tobacco cells was evaluated. Biological results were correlated with photophysical properties and the reactive oxygen species production capacity of tested compounds. Surprisingly, the anionic free-base porphyrin showed the strongest phototoxic effect.
