Novel DNA photocleavage properties of [Cr(NN)3]3+ complexes
(Elsevier Science, 2012-01)
The aim of this study was to investigate the ability of chromium(III) tris-diimine complexes, [Cr(NN)3]3+, to induce DNA photodamage and to examine its capability to impair the survival of irradiated bacteria with the ...
New insights in the DNA-[Cr(phen)2(dppz)]3+ binding and photocleavage properties by the complex with an intercalating ligand
(Elsevier Science Inc, 2010-07)
Due to the key role of DNA in cell life and pathological processes, the design of specific chemical nucleases, fic chemical nucleases, DNA probes and alkylating agents is an important research area for the development of ...
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 ...
Mechanistic insight of the photodynamic inactivation of Escherichia coli by a tetracationic zinc(II) phthalocyanine derivative
(Elsevier Science, 2009-03)
Photodynamic inactivation (PDI) of Escherichia coli has been studied in cultures treated with zinc(II) 2,9,16,23-tetrakis[4-(N-methylpyridyloxy)]phthalocyanine (ZnPPc+4) to obtain insight about the mechanism of damage. ...
