A CoII complex for19F MRI-based detection of reactive oxygen species

A fluorinated, air-stable cobalt(ii) complex serves as a turn-on19F magnetic resonance imaging (MRI) tracer for reactive oxygen species including H2O2. Upon oxidation with H2O2, the complex converts from paramagnetic high spin CoII to diamagnetic low spin CoIII resulting in a chemical shift change and enhancement in19F NMR signal. Further, the oxidation can be reversed in the presence of reductant Na2S2O4. The turn-on response is demonstrated by19F MRI, characterized by a ～2-3 fold enhancement in signal.

Gd3+-based magnetic resonance imaging contrast agent responsive to Zn2+

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 that involved the prepar
