    • 17O and 1H relaxometric and DFT study of hyperfine coupling constants in [Mn(H2O)6]2+ 

      Esteban-Gómez, David; Cassino, Claudio; Botta, Mauro; Platas-Iglesias, Carlos (Royal Society of Chemistry, 2014-01-06)
      [Abstract] Nuclear Magnetic Relaxation Dispersion (NMRD) profiles and 17O NMR chemical shifts and transverse relaxation rates of aqueous solutions of [Mn(H2O)6]2+ were recorded to determine the parameters governing the ...
    • 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 ...
    • 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: ...
    • High relaxivity Mn2+-based MRI contrast agents 

      Regueiro-Figueroa, Martín; Rolla, Gabriele A.; Esteban-Gómez, David; Blas, Andrés de; Rodríguez-Blas, Teresa; Botta, Mauro; Platas-Iglesias, Carlos (Wiley, 2014-12-16)
      [Abstract] Stable Mn2+ mono- and binuclear complexes containing pentadentate 6,6′-((methylazanediyl)bis(methylene)) dipicolinic acid coordinating units give remarkably high relaxivities due to the presence of two inner-sphere ...
    • Importance of outer-sphere and aggregation phenomena in the relaxation properties of phosphonated gadolinium complexes with potential applications as MRI contrast agents 

      Elhabiri, Mourad; Abada, Sabah; Sy, Mohamadou; Nonat, Aline; Choquet, Philippe; Esteban-Gómez, David; Cassino, Claudio; Platas-Iglesias, Carlos; Botta, Mauro; Charbonnière, Loïc J. (Wiley, 2015-04-10)
      [Abstract] A series composed of a tetra-, a tris- and a bisphosphonated ligand based on a pyridine scaffold (L4, L3 and L2, respectively) was studied within the frame of lanthanide (Ln) coordination. The stability constants ...
    • Optimising the relaxivities of Mn2+ complexes by targeting human serum albumin (HSA)
