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 ... -
Bifunctional Paramagnetic and Luminescent Clays Obtained by Incorporation of Gd³⁺ and Eu³⁺ Ions in the Saponite Framework
Marchesi, Stefano; Bisio, Chiara; Lalli, Daniela; Marchese, Leonardo; Platas-Iglesias, Carlos; Carniato, Fabio (American Chemical Society, 2021-07-08)[Abstract] A novel bifunctional saponite clay incorporating gadolinium (Gd³⁺) and europium (Eu³⁺) in the inorganic framework was prepared by one-pot hydrothermal synthesis. The material exhibited interesting luminescent ... -
Controlling Water Exchange Rates in Potential Mn²⁺-Based MRI Agents Derived From NO2A²⁻
Pujales-Paradela, Rosa; Carniato, Fabio; Esteban-Gómez, David; Botta, Mauro; Platas-Iglesias, Carlos (Royal Society of Chemistry, 2019-02-22)[Abstract] We report a series of pentadentate ligands based on a 1,4,7-triazacyclononane-1,4-diacetic acid (H2NO2A) containing different substituents attached to the third nitrogen atom of the macrocyclic unit. Detailed ... -
Defining the Conditions for the Development of the Emerging Class of Feᴵᴵᴵ-Based MRI Contrast Agents
Baranyai, Zsolt; Carniato, Fabio; Nucera, Alessandro; Horváth, Dávid; Tei, Lorenzo; Platas-Iglesias, Carlos; Botta, Mauro (Royal Society of Chemistry, 2021-07-26)[Abstract] Fe(III) complexes are attracting growing interest in chemists developing diagnostic probes for Magnetic Resonance Imaging because they leverage on an endogenous metal and show superior stability. However, in ... -
Definition of the labile capping bond effect in lanthanide complexes
Rodríguez-Rodríguez, Aurora; Regueiro-Figueroa, Martín; Esteban-Gómez, David; Rodríguez-Blas, Teresa; Patinec, Véronique; Tripier, Raphaël; Tircsó, Gyula; Carniato, Fabio; Botta, Mauro; Platas-Iglesias, Carlos (Wiley, 2017-01-23)[Abstract] Two macrocyclic ligands containing a cyclen unit, a methyl group, a picolinate arm, and two acetate pendant arms attached to two nitrogen atoms of the macrocycle either in trans (1,7-H3Medo2 ampa = 2,2′-(7-((6 ... -
Dimer formation of GdDO3A-arylsulfonamide complexes causes loss of pH-dependency of relaxivity
Wacker, Anja; Carniato, Fabio; Platas-Iglesias, Carlos; Esteban-Gómez, David; Wester, Hans-Jürgen; Tei, Lorenzo; Notni, Johannes (Royal Society of Chemistry, 2017-11-06)[Abstract] Gadolinium(III) complexes with pH-dependent relaxivities have been proposed as responsive magnetic resonance imaging (MRI) contrast agents (CA) for mapping of pH value in living subjects. The latter is clinically ... -
Surprising Complexity of the [Gd(AAZTA)(H2O)2]− Chelate Revealed by NMR in the Frequency and Time Domains
Lalli, Daniela; Carniato, Fabio; Tei, Lorenzo; Platas-Iglesias, Carlos; Botta, Mauro (American Chemical Society, 2021-12-10)[Abstract] Typically, Ln(III) complexes are isostructural along the series, which enables studying one particular metal chelate to derive the structural features of the others. This is not the case for [Ln(AAZTA)(H2O)x]− ...
