Journal ArticleDOI
Two new ternary complexes of copper(II) with tetracycline or doxycycline and 1,10-phenanthroline and their potential as antitumoral: cytotoxicity and DNA cleavage.
Priscila Pereira Silva,Wendell Guerra,Josiane N Silveira,Ana Maria da Costa Ferreira,Tiago Bortolotto,Franciele L. Fischer,Hernán Terenzi,Ademir Neves,Elene C. Pereira-Maia +8 more
TL;DR: The binding of the new complexes to DNA, their capacity to cleave it, their cytotoxic activity, and uptake in tumoral cells are evaluated; they are among the most potent DNA cleavage agents reported so far.
Journal ArticleDOI
Equilibrium characterization of the As(III)-cysteine and the As(III)-glutathione systems in aqueous solution
TL;DR: This paper reports on a study of the interactions between arsenic(III) and either cysteine or glutathione in aqueous solution, and the behavior observed for the As(III)-glutathione system is very similar to that of As( III)-cysteine.
Journal ArticleDOI
Electronic Structure and Spectro-Structural Correlations of FeIIIZnII Biomimetics for Purple Acid Phosphatases: Relevance to DNA Cleavage and Cytotoxic Activity
Rosely A. Peralta,Adailton J. Bortoluzzi,Bernardo de Souza,Rafael Jovito,Fernando R. Xavier,Ricardo Alexandre Alves de Couto,Annelise Casellato,Faruk Nome,Andrew Dick,Lawrence R. Gahan,Gerhard Schenk,Graeme R. Hanson,Flávia C. S. de Paula,Elene C. Pereira-Maia,Sergio Machado,Patricia Cardoso Severino,Claus Tröger Pich,Tiago Bortolotto,Hernán Terenzi,Eduardo E. Castellano,Ademir Neves,Mark J. Riley +21 more
TL;DR: This study establishes benchmarks against accurate crystallographic structural information using spectroscopic techniques that are not restricted to single crystals and shows that the cytotoxic activity of the biomimetics on leukemia and lung tumoral cells is highest for complexes with electron-donating groups.
Journal ArticleDOI
Synthesis, characterization, and antibacterial activity of three palladium(II) complexes of tetracyclines.
Wendell Guerra,Elaine de Andrade Azevedo,Ana Raquel de Souza Monteiro,Mônica Bucciarelli-Rodriguez,Edmar Chartone-Souza,Andréa M. A. Nascimento,Ana Paula Soares Fontes,Laurence Le Moyec,Elene C. Pereira-Maia +8 more
TL;DR: The Pd(II) complex of tetracycline is practically as efficient as tetrACYcline in inhibiting the growth of two Escherichia coli (E. coli) sensitive bacterial strains and 16 times more potent against E. coli HB101/pBR322, a bacterial strain resistant to tetr Tracycline.
Journal ArticleDOI
Synthesis, structure and properties of unsymmetrical μ-alkoxo-dicopper(II) complexes: biological relevance to phosphodiester and DNA cleavage and cytotoxic activity
Liane M. Rossi,Ademir Neves,Adailton J. Bortoluzzi,Rosmari Hörner,Bruno Szpoganicz,Hernán Terenzi,Antonio S. Mangrich,Elene C. Pereira-Maia,Eduardo E. Castellano,Wolgang Haase +9 more
TL;DR: In this article, the ability of complex 1 to promote the hydrolysis of P-O phosphate diester bonds in bis(4-dinitrophenyl) phosphate (2,4-BDNPP) and the cleavage of genomic and plasmid DNA molecules was investigated.
