    • Exceptionally inert lanthanide(III) PARACEST MRI contrast agents based on an 18-membered macrocyclic platform 

      Castro, Goretti; Regueiro-Figueroa, Martín; Esteban-Gómez, David; Bastida, Rufina; Macías, Alejandro; Pérez-Lourido, Paulo; Platas-Iglesias, Carlos; Valencia, Laura (Wiley, 2015-12-14)
      [Abstract] We report a macrocyclic ligand based on a 3,6,10,13-tetraaza-1,8(2,6)-dipyridinacyclotetradecaphane platform containing four hydroxyethyl pendant arms (L1) that forms extraordinary inert complexes with Ln3+ ions. ...
    • Expanding the Ligand Classes Used for Mn(II) Complexation: Oxa-aza Macrocycles Make the Difference 

      Kálmán, Ferenc; Nagy, Viktória; Uzal-Varela, Rocío; Pérez-Lourido, Paulo; Esteban-Gómez, David; Garda, Zoltán; Pota, Kristof; Mezei, Roland; Pallier, Agnès; Tóth, Éva; Platas-Iglesias, Carlos; Tircsó, Gyula (MDPI, 2021-03-10)
      [Abstract] We report two macrocyclic ligands based on a 1,7-diaza-12-crown-4 platform functionalized with acetate (𝑡O2DO2A²⁻) or piperidineacetamide (𝑡O2DO2AMᴾⁱᵖ) pendant arms and a detailed characterization of the ...
    • Inert macrocyclic Eu3+ complex with affirmative paraCEST features 

      Gambino, Tanja; Valencia, Laura; Pérez-Lourido, Paulo; Esteban-Gómez, David; Zaiss, Moritz; Platas-Iglesias, Carlos; Angelovski, Goran (Royal Society of Chemistry, 2020-06-21)
      [Abstract]: We report on a macrocyclic platform based on an 18-membered macrocycle that forms kinetically highly inert paramagnetic complexes and possesses an excellent outlook for the development of bioresponsive paraCEST ...
    • Magnetic anisotropies in rhombic lanthanide(III) complexes do not conform to Bleaney’s theory 

      Castro, Goretti; Regueiro-Figueroa, Martín; Esteban-Gómez, David; Pérez-Lourido, Paulo; Platas-Iglesias, Carlos; Valencia, Laura (American Chemical Society, 2016-04-04)
      [Abstract] We report a complete set of magnetic susceptibilities of lanthanide complexes with a macrocyclic ligand based on a 3,6,10,13-tetraaza-1,8(2,6)-dipyridinacyclotetradecaphane platform containing four hydroxyethyl ...
    • 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 ...
    • The relationship between NMR chemical shifts of thermally polarized and hyperpolarized 89Y complexes and their solution structures 

      Xing, Yixun; Jindal, Ashish K.; Regueiro-Figueroa, Martín; Le Fur, Mariane; Kervarec, Nelly; Zhao, Piyu; Kovacs, Zoltan; Valencia, Laura; Pérez-Lourido, Paulo; Tripier, Raphaël; Esteban-Gómez, David; Platas-Iglesias, Carlos; Sherry, A. Dean (Wiley, 2016-11-07)
      [Abstract] Recently developed dynamic nuclear polarization (DNP) technology offers the potential of increasing the NMR sensitivity of even rare nuclei for biological imaging applications. Hyperpolarized 89Y is an ideal ...
    • The role of ligand to metal charge-transfer states on the luminescence of Europium complexes with 18-membered macrocyclic ligands 

      Nonat, Aline; Esteban-Gómez, David; Valencia, Laura; Pérez-Lourido, Paulo; Barriada, José Luis; Charbonnière, Loïc J.; Platas-Iglesias, Carlos (Royal Society of Chemistry, 2019-02-27)
      [Abstract] We report a detailed study of the photophysical properties of EuIII and TbIII complexes with two ligands based on a 3,6,10,13-tetraaza-1,8(2,6)-dipyridinacyclotetradecaphane platform containing either four ...
