  • Selective treatment of endothelial somatostatin receptors
    Publication number: 20060089299
    Abstract: The invention provides for the use of somatostatin receptor selective ligands (selective for SSTR1 or SSTR4) to treat human endothelial cells and to formulate medicaments for human use. The medicaments may for example be used to treat an angiogenic disease. In various embodiments, the angiogenic disease may for example be macular degeneration or a solid tumor. The SSTR1 or SSTR4 selective agonists may include the SSTR1 agonist (des-AA1,2,5[DTrp8,IAamp9]SS).

  • Photodynamic therapy in selective cell inactivation in blood and treating immune dysfunction diseases
    Publication number: 20050130952
    Abstract: Multiple sclerosis and rheumatoid arthritis can be treated effectively using photodynamic therapy. In this protocol, a photoactive compound is administered, allowed to distribute in the effected subject, and the subject is then irradiated to activate the photoactive compound. Alternatively, the blood of a subject to be treated can be subjected to PDT extracorporeally. In the case of rheumatoid arthritis, localized treatment at the joints may also be employed.

  • Methods to treat arterial plaque
    Patent number: 6235767
    Abstract: A method to prevent or inhibit the development of arterial plaque, comprising the steps of: a. administering to a subject an amount of a green porphyrin compound effective to prevent or inhibit said development; and b. allowing the inhibition to occur in the absence of irradiation with light absorbed by the green porphyrin, or a pharmaceutical composition for preventing or inhibiting the development of arterial plaque. The composition comprises: a. an amount of a green porphyrin compound effective to prevent or inhibit the development when administered to a subject in need of such treatment, even in the absence of irradiation with light absorbed by said the green porphyrin; and b. a pharmaceutically acceptable excipient. The administration of the green porphyrin need not be accompanied by any purposeful irradiation with light.
