- 16. The compound of claim 10 where R2 is methyl.
- 17. The compound of claim 1 where R8 is —CH2CH2COR12.
- 18. The compound of claim 17 where R12 is —OR14 where R14 is lower alkyl.
- 19. A method for treating cancer cells which includes the steps of exposing the cells to a compound of claim 1 and exposing the cells to light at a dose rate of from about 5 to about 50 mW/cm2 at a wave length of from about 400 to about 800 nm, the cells being exposed to sufficient compound to inhibit their growth after said exposure.
- 20. A method for treating cancer cells which includes the steps of exposing the cells to a compound of claim 2 and exposing the cells to light at a dose rate of from about 5 to about 50 mW/cm2 at a wave length of from about 400 to about 800 nm, the cells being exposed to sufficient compound to inhibit their growth after said exposure.
- 21. A method for treating cancer cells which includes the steps of exposing the cells to a compound of claim 4 and exposing the cells to light at a dose rate of from about 5 to about 50 mW/cm2 at a wave length of from about 400 to about 800 nm, the cells being exposed to sufficient compound to inhibit their growth after said exposure.
- 22. A method for treating cancer cells which includes the steps of exposing the cells to a compound of claim 10 and exposing the cells to light at a dose rate of from about 5 to about 50 mW/cm2 at a wave length of from about 400 to about 800 nm, the cells being exposed to sufficient compound to inhibit their growth after said exposure.
- 23. A method for treating cancer cells which includes the steps of exposing the cells to a compound of claim 16 and exposing the cells to light at a dose rate of from about 5 to about 50 mW/cm2 at a wave length of from about 400 to about 800 nm, the cells being exposed to sufficient compound to inhibit their growth after said exposure.
- 24. The method of claim 19 where the cells are exposed to the compound at a solution concentration of from about 1 to about 20 gM.
- 25. The method of claim 20 where the cells are exposed to the compound at a solution concentration of from about 1 to about 20 μM.
