    • 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 ...

    • 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 ...

    • Developing the family of picolinate ligands for Mn2+ complexation 

      Forgács, Attila; Pujales-Paradela, Rosa; Regueiro-Figueroa, Martín; Valencia, Laura; Esteban-Gómez, David; Botta, Mauro; Platas-Iglesias, Carlos (Royal Society of Chemistry, 2016-12-22)
      [Abstract] We have reported here a series of ligands containing pentadentate 6,6′-(azanediylbis(methylene))dipicolinic acid units that differ in the substituent present at the amine nitrogen atom (acetate: H3DPAAA; phenyl: ...

    • Reinforced Ni(ɪɪ)-Cyclam Derivatives as Dual ¹H/¹⁹F MRI Probes 

      Pujales-Paradela, Rosa; Savic, Tanja; Brandariz, Isabel; Pérez-Lourido, Paulo; Angelovski, Goran; Esteban-Gómez, David; Platas-Iglesias, Carlos (Royal Society of Chemistry, 2019-03-11)
      [Abstract] Reinforced cross-bridged Ni²⁺-cyclam complexes were functionalised with pendant arms containing both amide protons and CF₃ groups that lead to a dual ¹H/¹⁹F response. The resulting complexes possess very high ...

    • Versatile Macrocyclic Platform for the Complexation of [ⁿᵃᵗY/⁹⁰Y]Yttrium and Lanthanide Ions 

      Harriswangler, Charlene; Caneda-Martínez, Laura; Rousseaux, Olivier; Esteban-Gómez, David; Fougère, Olivier; Pujales-Paradela, Rosa; Valencia, Laura; Fernández-Pérez, María-Isabel; Lepareur, Nicolas; Platas-Iglesias, Carlos (American Chemical Society, 2022-04-14)
      [Abstract] We report a macrocyclic ligand (H3L6) based on a 3,6,10,13-tetraaza-1,8(2,6)-dipyridinacyclotetradecaphane platform containing three acetate pendant arms and a benzyl group attached to the fourth nitrogen atom ...

    • Water exchange rates and mechanisms in tetrahedral [Be(H2O)4]2+ and [Li(H2O)4]+ complexes using DFT methods and cluster‐continuum models 

      Regueiro-Figueroa, Martín; Esteban-Gómez, David; Pujales-Paradela, Rosa; Caneda-Martínez, Laura; Blas, Andrés de; Platas-Iglesias, Carlos (Wiley, 2016-10-05)
      [Abstract] The water exchange reactions in aquated Li+ and Be2+ ions were investigated with density functional theory calculations performed using the [Li(H2O)4]+·14H2O and [Be(H2O)4]2+·8H2O systems and a cluster‐continuum ...
