nanostructures bearing two intercalating moieties was designed and synthesized to achieve selective recognition of DNA sequences. A cationicporphyrin was attached to a glutamic acid side chain and the latter introduced into a peptidic sequence by standard solid-phase peptide synthesis methodology. Conformation of the hydrosoluble peptidic structures bearing two cationicporphyrins was studied by circular
The present invention relates to novel porphyrin and porphyrin-based chromophores and sets of porphyrin and porphyrin-based chromophores, which may be particularly useful in a range of photodynamic applications, including photochemotherapy and fluorescence analysis and imaging. In particular, the present invention provides new and useful porphyrin, chlorin and bacteriochlorin chromophores; methods for the production of such chromophores; and methods for the use of such chromophores in analysis and in medicine.
Six monophenyltripyridylporphyrin derivatives were synthesized and characterized by spectroscopy in order to demonstrate their potential usefulness as photosensitizers for anticancer therapy purposes. Compounds 1 and 3–5 are amphiphilic, thus they may be suitable for transfer inside cells. Photochemical parameters such as fluorescence yield and singlet oxygen yield were determined. The former parameter

The present invention has identified thiaprophyrin, selenaporphyrin, and carotenoid porphyrin compounds that bind the G-quadruplex formed by the folding of single-stranded human telomeric DNA. These compounds have been shown to be effective telomerase and c-myc inhibitors and are contemplated to be useful in developing cancer treatments.
