    • 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: ...

    • Innovative smart probes for molecular imaging applications 

      Pujales-Paradela, Rosa (2019)
      [Abstract] The main purpose of the present doctoral thesis is the development of new systems based on metal complexes for their application as contrast agents in Magnetic Resonance Imaging (MRI). To achieve this aim, ...

      Pujales-Paradela, Rosa (2013)
      [Resumen]En este Trabajo de Fin de Grado (TFG) se ha llevado a cabo la preparación y caracterización morfológica y estructural de nanopartículas de magnetita, Fe3O4. Las nanopartículas de Fe3O4 se han preparado ...

    • 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 ...
