CoCEST: cobalt(II) amide-appended paraCEST MRI contrast agents.

The first examples of air-stable Co(II) paraCEST MRI contrast agents are reported. Amide NH protons on the complexes give rise to CEST peaks that are shifted up to 112 ppm from the bulk water resonance. One complex has multiple CEST peaks that may be useful for ratiometric mapping of pH.

Seven-Coordinate CoII, FeII and Six-Coordinate NiII Amide-Appended Macrocyclic Complexes as ParaCEST Agents in Biological Media

The solution chemistry and solid-state structures of the Co(II), Fe(II), and Ni(II) complexes of 7,13-bis(carbamoylmethyl)-1,4,10-trioxa-7,13-diazacyclopentadecane (L) are reported as members of a new class of paramagnetic chemical exchange saturation transfer (paraCEST) MRI contrast agents that contain transition metal ions. Crystallographic data show that nitrogen and oxygen donor atoms of th...

Synthesis and Evaluation of PARACEST MRI Contrast Agents Containing an Amino Acid Arginine

Introduction: Considering their excellent sensitivity to environmental conditions (e.g. temperature, pH), there is growing interest in the design and synthesis of paramagnetic chemical exchange saturation transfer (PARACEST) MRI contrast agents (CAs) (1). We have recently established a wide scope synthetic methodology for the preparation of mono-, diand tripeptide decorated cyclens and their la...

Polymeric PARACEST MRI contrast agents as potential reporters for gene therapy.

Gene therapy is a potentially powerful treatment approach that targets molecular remedies for disease. Among other challenges it remains difficult to monitor gene delivery and its downstream metabolic consequences. Approaches to MRI gene reporters have been reported but few have the potential for translation beyond isolated cell systems. Herein, we report a polycationic polymer MRI contrast age...

Development of Spontaneously Disassembling Dendrimers as a Platform Technology for PARACEST MRI Contrast Agents

PARACEST MRI contrast agents have been incorporated into nanocarriers to improve PARACEST sensitivity. Spontaneously disassembling dendrimers are nanocarriers can carry high payloads of chemotherapies to pathological tissues, and then rapidly release the chemotherapies during enzyme-triggered spontaneous disassembly of the dendrimers. To investigate whether a spontaneously disassembling systems...
