Abstract: Novel tumor specific phototherapeutic and photodiagnostic agents are disclosed. The compounds consist of a carbocyanine dye for visualization, photosensitizer for photodynamic treatment, and tumor receptor-avid peptide for site-specific delivery of the probe and phototoxic agent to diseased tissues. A combination of these elements takes full advantage of the unique and efficient properties of each component for an effective patient care management.

Abstract: Novel azo, azide, and sulfenate photoactive compounds and methods using the compounds for photodiagnostic and/or phototherapeutic procedures. The compounds have the formula E-L-DYE-X—Y, wherein DYE is a photoactive component comprising a photoactive diagnostic agent, a photoactive type 1 agent, a photoactive type 2 agent, or a combination thereof; Y is a photoactive component comprising a photoactive type 1 agent, a photoactive type 2 agent, or a combination thereof; E is a targeting component for targeting the compound to an anatomical and/or physiological site of a patient; L is a linking component for linking E to DYE; and X is a linking component for linking DYE to Y.

Abstract: Highly hydrophilic indole and benzoindole derivatives that absorb and fluoresce in the visible region of light are disclosed. These compounds are useful for physiological and organ function monitoring. Particularly, the molecules of the invention are useful for optical diagnosis of renal and cardiac diseases and for estimation of blood volume in vivo.

Abstract: The present invention discloses novel aromatic azide derivatives and their bioconjugates for phototherapy of tumors and other lesions. The organic azides of the present invention are designed to absorb low-energy ultraviolet, visible, or near-infrared (NIR) region of the electromagnetic spectrum. The phototherapeutic effect is caused by direct interaction of nitrene, the reactive intermediate produced upon photoexcitation of the aromatic azide, with the tissue of interest. The compounds of the present invention are administered to a patient, allowed to accumulate at the site of the tumor or other lesion, and are exposed to light in order to perform a phototherapeutic procedure.

Abstract: The present invention discloses dye-azide derivatives and their bioconjugates for dual phototherapy of tumors and other lesions. The compounds of the present invention may contain either a mixture of Type 1 and Type 2 agents or a single entity that integrates both units in the same molecules. The compounds are designed to produce both Type 1 and Type 2 phototherapeutic effect at once using dual wavelength light source that will produce singlet oxygen and nitrene at the lesion of interest.
