Lanthanide complexes with a series of hexapeptides-incorporating two unnatural chelating amino acids with aminodiacetate groups, Ada(1) and Ada(2)-have been examined in terms of their speciation, structure, stability and luminescence properties. Whereas Ada(2) acts as a tridentate donor in all cases, Ada(1) may act as a tetradentate donor thanks to the coordination of the amide carbonyl function assisted by the formation of a six-membered chelate ring. The position of the Ada(1) residue in the…

The impact of structural variation in simple lanthanide binding peptides
TLDR
A deeper understanding of how peptide structure affects lanthanide binding affinity has been gained and the potential of these peptides as selective ligands for separations at acidic pH has been demonstrated.
Femtomolar Ln(III) affinity in peptide-based ligands containing unnatural chelating amino acids.
TLDR
It is demonstrated that unnatural amino acids carrying polyaminocarboxylate side-chains are interesting building blocks to design high affinity Ln-binding peptides.
Rational design of lanthanide binding peptides
Engineering short peptide sequences for uranyl binding.
TLDR
The molar ellipticity of the uranyl complex at 195 nm is directly correlated to its stability, which demonstrates that the β-sheet structure is optimal for high stability in the peptide series.
DNA sensing by a Eu-binding peptide containing a proflavine unit.
TLDR
The Eu(3+)-LBP complex is demonstrated to bind to ct-DNA and to sensitize Eu luminescence and the DNA binding process is effectively detected via the Eu-centered luminescent thanks to the intimate coupling between the LBP scaffold and DNA intercalating unit.

Lanthanide(III) complexes with two hexapeptides incorporating unnatural chelating amino acids: secondary structure and stability.
TLDR
Study of the lanthanide complexes of the two peptides Pn by luminescence titrations, mass spectrometry, circular dichroism, and solution NMR spectroscopy demonstrate that the Ada(n) chain length has a dramatic effect on the complexation properties.
A series of tripodal cysteine derivatives as water-soluble chelators that are highly selective for copper(I).
TLDR
Two sulfur-based tripods L(1) and L(2) are of potential interest for intracellular copper detoxication in vivo, without altering the homeostasis of the essential metal ion Zn(II).

TLDR
These derivatives can be conveniently used in a solid-phase peptides synthesis as they are devoid of serious shortcomings of Boc/Bzl based syntheses of metallopeptides, such as preliminary peptide capping as well as undesired lactamization of 5 during the peptide synthesis.
Cationic lanthanide complexes of neutral tripodal N,O ligands: enthalpy versus entropy-driven podate formation in water.
TLDR
The analysis of the proton lanthanide induced NMR shifts indicate that there is no abrupt structural change in the middle of the rare-earth series.

TLDR
A new cyclodecapeptide incorporating two prolylglycine sequences as beta-turn inducers and bearing four side chains with acidic carboxyl groups for cation complexation has been prepared and a large second-sphere (2S) contribution to the relaxivity caused by the interaction of water molecules with the hydrophilic peptide ligand by hydrogen-bonding is proposed.
