RESUMO
Two new cyclic hexapeptoids incorporating N-carboxyethylglycine and N-methoxyethylglycine residues are able to efficiently bind Gd(3+). Their thermodynamic stabilities and relaxivities have been assessed by (1)H-relaxometric investigations.

RESUMO
N-Benzyloxyethyl macrocyclic peptoids 3 and 4 were synthesized and subjected to alkali metal binding studies; these compounds, plus the known 1 and 2, when subjected to ion transport studies, demonstrated size-dependent selectivity for the first group alkali metals cation transport.

RESUMO
L-Proline and N-methoxyethyl glycine have been included in novel cyclic hexameric peptoids. Supramolecular coordination with Na(+) triggered the formation of the first 1D metal-organic framework based on peptoids.
