Synthesis and characterisation of bismacrocyclic DO3A-amide derivatives – an approach towards metal-responsive PARACEST agents
(Royal Society of Chemistry, 2016-02-26)
[Abstract] Three new bismacrocyclic Ln3+ chelates consisting of triamide derivatives of cyclen with glycine, methyl and tert-butyl substituents (L1–3, respectively) linked to an acyclic EGTA-derived calcium chelator were ...
Gd3+-based magnetic resonance imaging contrast agent responsive to Zn2+
(American Chemical Society, 2015-10-15)
[Abstract] We report the heteroditopic ligand H5L, which contains a DO3A unit for Gd3+ complexation connected to an NO2A moiety through a N-propylacetamide linker. The synthesis of the ligand followed a convergent route ...
Paramagnetic lanthanide chelates for multicontrast MRI
(Royal Society of Chemistry, 2016-06-02)
[Abstract] The preparation of a paramagnetic chelator that serves as a platform for multicontrast MRI, and can be utilized either as a T1-weighted, paraCEST or 19F MRI contrast agent is reported. Its europium(III) complex ...
Europium(III) Macrocyclic Chelates Appended with Tyrosine-based Chromophores and Di-(2-picolyl)amine-based Receptors: Turn-On Luminescent Chemosensors Selective to Zinc(II) Ions
(Wiley, 2020-01-22)
[Abstract] Zinc ions play an important role in many biological processes in the human body. To selectively detect Zn²⁺, two EuDO3A‐based complexes (DO3A=1,4,7,10‐tetraazacyclododecane‐1,4,7‐tricarboxylic acid) appended ...
