A novel design strategy for controlling the fluorescence and photosensitizing ability of thiazole orange (TO) has been developed. The validity of this approach was demonstrated by the synthesis of a B-galactosidase-activatable photosensitizer, PhoTO-Gal, in which fluorescence is simultaneously activated. PhoTO-Gal was demonstrated to kill HEK293 lacZ(+) cells, which express beta-galactosidase, but not HEK293 lacZ(-) cells, under light illumination. Such activatable photosensitizers should allow more refined PDT without the side effect of prolonged tight sensitivity and should also be useful as toots for reporter enzyme expression-specific cell ablation.
