  • Patent number: 6160024
    Abstract: Disclosed herein are compounds, compositions, and methods to inactivate a virus and destroy tumor cells. The methods involve the addition into the cell of a compound containing a photosensitizing chemical and an energy donating chemical, optionally linked by a chemical tether. Also introduced into the cell are means to chemically activate the energy donating chemical which photoactivates the photosensitizing chemical which then destroys the tumor or virus. The photosensitizing chemical is preferably hypericin, porphyrin, or an analog and the energy donating chemical is preferably luciferin or an analog. Methods for synthesizing the chemicals are also disclosed. Further, the energy donating chemical is activated by an activating chemical. The expression of the activating chemical is regulated so as to target the virus-infected or tumor cells.
    Type: Grant
