High relaxivity Mn2+-based MRI contrast agents
(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 ...
Transient versus static electron spin relaxation in Mn2+ complexes relevant as MRI contrast agents
(American Chemical Society, 2016-08-18)
[Abstract] The zero-field splitting (ZFS) parameters of the [Mn(EDTA)(H2O)]2–·2H2O and [Mn(MeNO2A)(H2O)]·2H2O systems were estimated by using DFT and ab initio CASSCF/NEVPT2 calculations (EDTA = 2,2′,2″,2‴-(ethane-1,2-di ...
Expanding the Ligand Classes Used for Mn(II) Complexation: Oxa-aza Macrocycles Make the Difference
(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 ...
