Porphyrin derivatives with hydroxyphenyl or dihydroxyphenyl moieties in the meso-position were able to dissolve in water by complexation with two trimethyl-β-cyclodextrins (TMe-β-CDxs) without further chemical modification of porphyrins or addition

Water-soluble inclusion complexes of 5,15-diazaporphyrin derivatives in the cavities of two trimethyl-β-cyclodextrins (TMe-β-CDxs) were synthesised. In the 2 : 1 complexes, two aryl groups of the diazaporphyrins protruded from the upper rims of two

5,15-Diazaporphyrins, which have a large absorption at wavelengths over 600 nm, were dissolved in water by complex formation with β-(1,3-1,6)-d-glucans. Aqueous solutions of these complexes were relatively stable compared with their trimethyl-β-cyc

Improvement of Photodynamic Activity of Lipid-Membrane-Incorporated Fullerene Derivative by Combination with a Photo-Antenna Molecule

Autor: Kouta Sugikawa, Hisakage Funabashi, Atsushi Ikeda, Tomoya Mae, Shuhei Satake, Daiki Antoku, Akio Kuroda

The weak absorbance of pristine C60, C70, and fullerene derivatives at wavelengths over 600 nm hampers the use of these molecules as photosensitizers (PSs) for photodynamic therapy (PDT). The coexistence of light-harvesting antenna molecules with a f

Photodynamic Activities of Porphyrin Derivative–Cyclodextrin Complexes by Photoirradiation

Autor: Masafumi Ueda, Shuhei Satake, Atsushi Ikeda, Tomoya Mae, Hajime Shigeto, Akio Kuroda, Kouta Sugikawa, Hisakage Funabashi

Water-soluble cyclodextrin (CyD)-complexed with porphyrin derivatives with different substituents in the mesopositions showed different photodynamic activities toward cancer cells under illumination at wavelengths over 600 nm, the most suitable wavel
