    摘要： Provided are a photosensitizer-metal nanoparticle charge complex and a composition for photodynamic therapy or diagnosis containing the same. The complex includes a metal nanoparticle, a photosensitizer charged with a first charge, and a linker bound to the metal nanoparticle and charged with a second charge having an opposite polarity to the first charge. During circulation in blood, the photosensitizer-metal nanoparticle charge complex is maintained in a complex type, and thus duration of a side effect of photosensitivity can be reduced. In a tumor tissue, the complex is specifically accumulated, but in a normal tissue, it is difficult for the complex to penetrate. Thus, the complex can selectively destroy the tumor tissue. Moreover, selective fluorescence in the tumor tissue can provide further improvement in accuracy of diagnosing a tumor using the complex.

    摘要： Provided are a photosensitizer-metal nanoparticle complex and a composition for photodynamic therapy or diagnosis having the same. The complex includes a photosensitizer, a metal nanoparticle, and a backbone linking the photosensitizer with the metal nanoparticle. The backbone has a polypeptide substrate capable of being specifically degraded by a protease. When the complex is administered to a patient, fluorescence and production of reactive oxygen species from the conjugated photosensitizers are inhibited in normal tissues due to the resonance energy transfer between the photosensitizer and metal nanoparticles, but in tumor tissues, fluorescence and production of reactive oxygen species from the released photosensitizers are activated, thereby effectively destroying the tumor tissues. In addition, the selective fluorescence in the tumor tissues can further improve accuracy of tumor diagnosis using the protease-activatable photosensitizer-metal nanoparticle complex.

More specifically, disclosed herein are a recombinant adenovirus comprising (1) a tissue-specific promoter, (2) a trans-splicing ribozyme acting on tumor-specific genes operably linked to the promoter, and (3) a therapeutic or reporter gene linked to 3′ exon of the ribozyme, an anticancer pharmaceutical composition comprising the same, and a composition for cancer diagnosis comprising the same.The recombinant adenovirus exhibits high specificity and significantly improved therapeutic efficacy to gene targeted tissues. Accordingly, the recombinant adenovirus is useful as a gene delivery vector for anticancer agents or cancer diagnostics.
