Investigation and Characterization of Novel Pentamethine Cyanine Dyes for Use as Photosensitizers in Photodynamic Therapy

Cyanine dyes that absorb light in the near infrared to far red region of the electromagnetic spectrum are desirable as photosensitizers for photodynamic cancer therapy. Light of wavelengths in this range is able to deeply penetrate tissue allowing for practical in vivo use of these dyes. A series of three structurally similar pentamethine cyanine dyes that absorb light ~800 nm to ~500 nm was tested to determine the effects of structural influences on the yields of supercoiled DNA photo-converted to nicked or linear forms. Possible mechanisms and optimal parameters for near- quantitative DNA photocleavage with a symmetrical quinoline pentamethine cyanine dye are discussed.
