Dano ao DNA induzido por fotoclivagem e análise citotóxica de uma porfirina meso-tetra-rutenada sob irradiação por luz visível
(Universidade Federal de Santa MariaBrasilBioquímicaUFSMPrograma de Pós-Graduação em Ciências Biológicas: Bioquímica ToxicológicaCentro de Ciências Naturais e Exatas, 2020-12-03)
Photodynamic Therapy (PDT) combined with the use of molecules containing the porphyrin ring associated with ruthenium transition metal has become an alternative method to the traditional treatment of melanoma. Here, we ...
Multimetallic porphyrins/polyoxotungstate modified electrodes by layer-by-layer method: Electrochemical, spectroscopic and morphological characterization
(PERGAMON-ELSEVIER SCIENCE LTD, 2012)
This work describes the formation of modified electrodes layer-by-layer assembly of a mu-{meso-5,10,15,20-tetra(pyridyl)porphyrin}terrakis{bis(bipyridine)chloride ruthenium(II)} coordinated with Zn(II) and Mn(III) in its ...
Correlation of photodynamic activity and singlet oxygen quantum yields in two series of hydrophobic monocationic porphyrins
(WORLD SCI PUBL CO INCHACKENSACK, 2012-01)
The photodynamic properties of eight hydrophobic monocationic methyl and ruthenium polypyridine complex derivatives of free-base and zinc(II) meso-triphenyl-monopyridylporphyrin series were evaluated and compared using ...
(5,10,15,20-Tetra(4-pyridil)porphinato)manganes(III) acetate modified by four mu(3)-oxo-triruthenium acetate clusters: synthesis, characterization, electrochemical behavior and catalytic activity
(Elsevier B.V., 2000-07-28)
A novel supermolecule constituted by four mu(3)-oxo-triruthenium acetate clusters coordinated to manganese(III)-meso -tetra(4-pyridil)porphyrin acetate ([MnTPyP]CH3COO) has been synthesized. Characterization has been ...

Langmuir and Langmuir-Blodgett films containing a porphyrin-ruthenium complex
(Amer Scientific Publishers, 2005-06-01)
The fabrication of supramolecular structures from the tetraruthenated porphyrin-containing phosphines, {TPyP[RuCl3(dppb)](4)}, RuTPyP, is demonstrated with Langmuir and Langmuir-Blodgett films. The surface pressure-molecular ...
