    • 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 ...

    • 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: ...

    • Highly relaxing gadolinium based MRI contrast agents responsive to Mg2+ sensing 

      Abada, Sabah; Lecointre, Alexandre; Elhabiri, Mourad; Esteban-Gómez, David; Platas-Iglesias, Carlos; Tallec, Gaylord; Mazzanti, Marinella; Charbonnière, Loïc J. (Royal Society of Chemistry, 2012-04-28)
      [Abstract] A Gd complex based on a polyphosphonated pyridyl ligand shows a very high stability in aqueous solution (logKEuL = 25.7), a high relaxivity (8.5 mM−1 s−1 at 25 °C and 20 MHz) and a marked and selective relaxivity ...

    • 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) 

      Forgács, Attila; Tei, Lorenzo; Baranyai, Zsolt; Esteban-Gómez, David; Platas-Iglesias, Carlos; Botta, Mauro (Royal Society of Chemistry, 2017-07-14)
      [Abstract] We report two novel macrocyclic ligands based on the 1,4-DO2AM platform (1,4-DO2AM = 2,2′-(1,4,7,10-tetraazacyclododecane-1,4-diyl)diacetamide) and containing two benzyl groups attached either to the nitrogen ...
