| Özet |
| The interaction of two water soluble phthalocyanines, cobalt(II) 4,4′,4″,4′″-tetrasulfo-phthalocyanine (CoTsPc) and iron(II) 4,4′,4″,4′″-tetrasulfo-phthalocyanine (FeTsPc), and one water soluble porphyrin, tetra sodium mesotetrakis(p-sulfophenyl) porphyrin (TSPP), with calf thymus DNA has been studied by UV-Vis spectroscopy at five different temperatures (20, 25, 30, 35, and 40°C). The optical absorption spectra of these materials were analyzed to obtain binding constants and stoichiometries using SQUAD software. The results show that the best fitting corresponds to a 1: 1 complex model between a base pair of DNA and these materials. All of the studied porphyrin and phthalocyanines showed strong electrolyte effect, and increasing NaCl concentration induced self-aggregation of these materials. © Nauka/Interperiodica 2007. |
