Autor: Ana Gabriela Conceição-Vertamatti, Luiz Alberto Ferreira Ramos, Ivy Calandreli, Aline Nunes Chiba, Douglas Wagner Franco, Elia Tfouni, Dora Maria Grassi-Kassisse

Publikováno v: Arquivos Brasileiros de Cardiologia, Vol 104, Iss 3, Pp 185-194 (2015)

Background: Ruthenium (Ru) tetraamines are being increasingly used as nitric oxide (NO) carriers. In this context, pharmacological studies have become highly relevant to better understand the mechanism of action involved. Objective: To evaluate the v

O comportamento Fotoquímico dos Complexos Pentaaminas de Rutênio(II) com Ligantes π Insaturados The photochemical behaviour of pentaamineruthenium(ii) complexes with unsaturated π ligands

Autor: Rose Maria Carlos, Elia Tfouni, Miguel G. Neumann

Publikováno v: Química Nova, Vol 20, Iss 3, Pp 270-278 (1997)

A general overview on the photochemical behaviour of [Ru(NH3)5L]2+ complexes (where L is a p ligand) is presented. The proposed mechanisms and techniques employed for the study of these reactions are discussed. Emphasis is made on the mechanisms that

Nitric oxide plays an important role in several physiological processes. This study investigates model ruthenium ammine coordination compounds to control NO bioavailability: cis-[RuCl(NO)(NH3)4]+ (1+), cis-[RuCl(NO)(NH3)4]2+ (12+), cis-[RuCl(NO)(NH3)

Phenotypic switching prevention and proliferation/migration inhibition of vascular smooth muscle cells by the ruthenium nitrosyl complex trans-[Ru(NO)Cl(cyclam](PF6)2

Autor: Elia Tfouni, Mariana G. de Oliveira, Fábio Gorzoni Doro, Marta Helena Krieger

Publikováno v: Journal of Pharmacy and Pharmacology. 69:1155-1165

Objectives Vascular smooth muscle cell (VSMC) migration and proliferation at sites of vascular injury are both critical steps in the development of intimal hyperplasia (IH). Local delivery of nitric oxide (NO) largely prevents these events. Among the

The versatile ruthenium(II/III) tetraazamacrocycle complexes and their nitrosyl derivatives

Autor: Zênis Novais da Rocha, Elia Tfouni, Anderson J. Gomes, Fabio Gorzoni Doro, Giovanni F. Caramori, Kleber Queiroz Ferreira

Publikováno v: Coordination Chemistry Reviews. 306:652-677

Macrocyclic ligands are relevant because of the properties they impart to transition metal complexes, such as enhanced thermodynamic stability and slowed substitution kinetic behavior. Here, we address issues not previously reviewed, revisit others,
