In this article the single family of conformations of adenosine 5'-monophosphate (5'AMP) in aqueous solution previously obtained using the lanthanide ions as nuclear magnetic resonance (NMR) probes is shown to disagree with the conformational data available from independent NMR methods, such as coupling constant and nuclear Overhauser enhancement analysis. The original lanthanide experimental data is reinterpreted assuming the contribution of different conformers to the observed magnetic perturbations. The average conformation obtained for 5'AMP agrees quite satisfactorily with the other independent conformational information.

Biocatalytic Polytransesterification of Inulin with Divinyladipate

Chemistry of Materials (2002)

Lino Ferreira M.H. Gil Rui A. Carvalho Carlos F. G. C. Geraldes Dae‐Yun Kim

This work was directed at extending the use of enzyme-catalyzed polytransesterification reactions to a polysaccharide. Inulin polyesters with Mn greater than 20 000 Da (corresponding to the polymerization of five units of inulin) were obtained with DVA molecules attached to the inulin backbone at the 6-position on the fructofuranoside residue, mainly by both ester termini (R2) and by a small extent through single ester termini (R1).

Gd(DO3A-N-α-aminopropionate): a versatile and easily available synthon with optimized water exchange for the synthesis of high relaxivity, targeted MRI contrast agents

Chemical Communications (2009)

Miguel Ferreira André F. Martins José A. Martins Paula M. T. Ferreira Éva Tóth

We report the synthesis of a novel, versatile and easily accessible metal chelator, DO3A-N-α-aminopropionate, and the relaxometric characterization of its Gd3+ complex, revealing great potential for the development of high relaxivity targeted contrast agents for magnetic resonance imaging.

Concentration‐Dependent Interactions of Amphiphilic PiB Derivative Metal Complexes with Amyloid Peptides Aβ and Amylin**

Chemistry - A European Journal (2020)

Saida Majdoub Zoltán Garda Alexandre C. Oliveira Inga Relich Agnès Pallier

Abstract Invited for the cover of this issue are Jean‐François Morfin and Éva Tóth at the CNRS in Orléans, and their collaborators from University of Debrecen, University of Coimbra and Université de Toulouse. The image depicts that when an amphiphilic compound is intravenously injected, monomer, pre‐micellar and micellar forms can co‐exist in the blood and have different affinities for amyloid peptides.
