A further study of acetylacetone nitrosation
Iglesias, Emilia; Brandariz, Isabel (Royal Society of Chemistry, 2013-02)The nitrosation of acetylacetone (AcAc) has been revised in an aqueous acid medium of perchloric acid and buffers of mono-, di-, or tri-chloroacetic acid. The results show that in the presence of buffers, under conditions ... -
A Pentadentate Member of the Picolinate Family for Mn(ɪɪ) Complexation and an Amphiphilic Derivative
Pujales-Paradela, Rosa; Carniato, Fabio; Uzal-Varela, Rocío; Brandariz, Isabel; Iglesias, Emilia; Platas-Iglesias, Carlos; Botta, Mauro; Esteban-Gómez, David (Royal Society of Chemistry, 2018-12-04)[Abstract] We report a pentadentate ligand containing a 2,2′-azanediyldiacetic acid moiety functionalized with a picolinate group at the nitrogen atom (H3paada), as well as a lipophylic derivative functionalized with a ... -
Endeavor toward Redox-Responsive Transition Metal Contrast Agents Based on the Cross-Bridge Cyclam Platform
Uzal-Varela, Rocío; Rodríguez-Rodríguez, Aurora; Lalli, Daniela; Valencia, Laura; Maneiro, Marcelino; Botta, Mauro; Iglesias, Emilia; Esteban-Gómez, David; Angelovski, Goran; Platas-Iglesias, Carlos (American Chemical Society, 2024-01-10)[Abstract]: We present the synthesis and characterization of a series of Mn(III), Co(III), and Ni(II) complexes with cross-bridge cyclam derivatives (CB-cyclam = 1,4,8,11-tetraazabicyclo[6.6.2]hexadecane) containing acetamide ... -
Fluorescence study of tetracaine–cyclodextrin inclusion complexes
Iglesias García, Iván.; Brandariz, Isabel; Iglesias, Emilia (Taylor and Francis Ltd., 2010-04)The steady-state fluorescence emission from the local anaesthetic tetracaine (TCA) in water-solvent mixtures and in the presence of α-, β- and γ-cyclodextrin (CD) was investigated at various pH values. Emission was observed ... -
Gold Nanoparticles as Colorimetric Sensors for the Detection of DNA Bases and Related Compounds
Iglesias, Emilia (MDPI, 2020-06-23)[Abstract] Results regarding interaction of colloidal gold solutions with nucleobases, including uracil (U), as well as its sulfur derivatives, 2-thiouracil (2TU) and 4-thiouracil (4TU), cytosine (C), adenine (A), and ... -
Iron(III) complexation by Vanchrobactin, a siderophore of the bacterial fish pathogen Vibrio anguillarum
Iglesias, Emilia; Brandariz, Isabel; Jiménez, Carlos; Soengas, Raquel G. (Royal Society of Chemistry, 2011-05)The bacterial fish pathogen Vibrio anguillarum serotype O2 strain RV22 produces the mono catecholate siderophore Vanchrobactin (Vb) under conditions of iron deficiency. Vb contains two potential bidentate coordination ... -
Micellar effects on aromatic esters hydrolysis
Brandariz, Isabel; Iglesias, Emilia (Elsevier, 2014-07)The alkaline hydrolysis of two aromatic esters, 2-naphthyl acetate (2NA) and phenyl acetate (PhA) has been tackled in this work. The reaction has been followed in water and in the presence of cationic surfactants with ... -
On the Dissociation Pathways of Copper Complexes Relevant as Pet Imaging Agents
Uzal-Varela, Rocío; Patinec, Véronique; Tripier, Raphaël; Valencia, Laura; Maneiro, Marcelino; Canle, Moisés; Platas-Iglesias, Carlos; Esteban-Gómez, David; Iglesias, Emilia (Elsevier, 2022)[Abstract] Several bifunctional chelators have been synthesized in the last years for the development of new 64Cu-based PET agents for in vivo imaging. When designing a metal-based PET probe, it is important to achieve ... -
Potentiometric characterisation of cyclodextrin inclusion complexes of local anaesthetics
Brandariz, Isabel; Iglesias, Emilia (Taylor and Francis Ltd., 2011-09)The complexation of several local anaesthetics by β and γ-cyclodextrins was studied by potentiometry with glass electrode. Tetracaine and dibucaine complexation constants were determined at 25°C in the presence of 0.1 M ... -
Solvent Effects versus Concentration Effects in determining Rates of Base-catalysed Keto-enol Tautomerization
Iglesias, Emilia (Royal Society of Chemistry, 2005)Solvent effects of homogeneous media (such as solvent-water mixtures) in chemical reactivity may be interpreted as due to solvent polarity and/or molecular structure of solvent molecules. In microheterogeneous media (such ... -
Tautomerization of 2-acetylcyclohexanone in assemblies of cationic surfactants. Nitrosation of the enol.
Iglesias, Emilia (Royal Society of Chemistry, 2005)The kinetic study of the keto-enol interconversion of 2-acetylcyclohexanone (ACHE) has been performed in organic solvents such as dimethylsulfoxide (DMSO), 1-propanol (1-PrOH), 2-propanol (2-PrOH), methanol (MeOH), dioxane, ...
