Understanding Paramagnetic Relaxation Phenomena for Water-Soluble Gadofullerenes

Autor: Lon J. Wilson, Éva Tóth, Robert D. Bolskar, Andre E. Merbach, Balaji Sitharaman, Sabrina Laus, Lothar Helm

Publikováno v: The Journal of Physical Chemistry C. 111:5633-5639

Water-soluble, endohedral gadofullerenes exhibit considerably higher relaxivities than clinically used Gd3+-chelates and are currently explored as potential magnetic resonance imaging (MRI) contrast agents. The relaxivities of Gd@C60(OH)x (x ≈ 27)

Publikováno v: The journal of physical chemistry. A. 111(25)

In the search for highly efficient magnetic resonance imaging contrast agents, polyamino polypyridine carboxylate complexes of Gd3+ have shown unusual properties with both very rapid and very slow electron spin relaxation in solution observed by elec

International audience; The EPTPA5) chelate, which ensures fast water exchange in GdIII complexes, has been coupled to three different generations (5, 7, and 9) of polyamidoamine (PAMAM) dendrimers through benzylthiourea linkages (H5EPTPA = ethylenep

GdIII complexes with fast water exchange and high thermodynamic stability: potential building blocks for high-relaxivity MRI contrast agents

Autor: Éva Tóth, Sabrina Laus, Robert Ruloff, Andre E. Merbach

Publikováno v: Chemistry (Weinheim an der Bergstrasse, Germany). 9(15)

On the basis of structural considerations in the inner sphere of nine-coordinate, monohydrated Gd(III) poly(aminocarboxylate) complexes, we succeeded in accelerating the water exchange by inducing steric compression around the water binding site. We

International audience; A combined proton relaxivity and dynamic light scattering study has shown that aggregates formed in aqueous solution of water-soluble gadofullerenes can be disrupted by addition of salts. The salt content of fullerene-based ma
