Reinforced Ni(ɪɪ)-Cyclam Derivatives as Dual ¹H/¹⁹F MRI Probes
(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 ...
Phosphate and polyphosphate anion recognition by a dinuclear copper(ii) complex of an unsymmetrical squaramide
(Royal Society of Chemistry, 2019-05-29)
[Abstract] In the search for receptors suitable for the recognition of phosphate or polyphosphate anions, a new unsymmetrical squaramide-based ligand bearing dipicolylamine (dpa) and ethylpiperazine units (L) was designed ...
On the Dissociation Pathways of Copper Complexes Relevant as Pet Imaging Agents
(Elsevier, 2022)
[Abstract] Several bifunctional chelators have been synthesized in the last years for the development of new 64Cu-based PET agents for in vivo imaging. When designing a metal-based PET probe, it is important to achieve ...
Accelerating water exchange in GdIII–DO3A-derivatives by favouring the dissociative mechanism through hydrogen bonding
(Royal Society of Chemistry, 2018-12-10)
[Abstract] The GdIII-complexes of DO3A-acetophenone and ortho- or para- hydroxyacetophenone ligands have been investigated to assess the effect of the presence of a phenol group on the relaxivity and on the water exchange ...
Controlling Water Exchange Rates in Potential Mn²⁺-Based MRI Agents Derived From NO2A²⁻
(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 ...
Relevance of Palladium to Radiopharmaceutical Development Considering Enhanced Coordination Properties of TE1PA
(Wiley, 2022-06-10)
[Abstract] The limited use of palladium-103 and -109 radionuclides for molecular radiotherapy is surely due to the lack of appropriate ligands capable of fulfilling all criteria required for application in nuclear medicine. ...
Versatile Macrocyclic Platform for the Complexation of [ⁿᵃᵗY/⁹⁰Y]Yttrium and Lanthanide Ions
(American Chemical Society, 2022-04-14)
[Abstract] We report a macrocyclic ligand (H3L6) based on a 3,6,10,13-tetraaza-1,8(2,6)-dipyridinacyclotetradecaphane platform containing three acetate pendant arms and a benzyl group attached to the fourth nitrogen atom ...
Dimer formation of GdDO3A-arylsulfonamide complexes causes loss of pH-dependency of relaxivity
(Royal Society of Chemistry, 2017-11-06)
[Abstract] Gadolinium(III) complexes with pH-dependent relaxivities have been proposed as responsive magnetic resonance imaging (MRI) contrast agents (CA) for mapping of pH value in living subjects. The latter is clinically ...
Thermodynamic Stability of Mn(II) Complexes with Aminocarboxylate Ligands Analyzed Using Structural Descriptors
(ACS, 2022-08-22)
[Abstract] We present a quantitative analysis of the thermodynamic stabilities of Mn(II) complexes, defined by the equilibrium constants (log KMnL values) and the values of pMn obtained as −log[Mn]free for total metal and ...
Diimidazolium Halobismuthates [Dim]2[Bi2X10] (X = Cl–, Br–, or I–): A New Class of Thermochromic and Photoluminescent Materials
(American Chemical Society (ACS), 2018-06-12)
[Abstract] We present a novel family of polyhalide salts of Bi(III) with the general formula [Dim]2[Bi2X10], where Dim2+ is the diimidazolium cation (C9H14N4)2+ and X is Cl–, Br–, or I–. Single-phase materials are easily ...
