Noncovalent Protein and Peptide Functionalization of Single-Walled Carbon Nanotubes for Biodelivery and Optical Sensing Applications

Ardemis Anoush Boghossian, Alessandra Antonucci, Justyna Kupis-Rozmyslowicz

The exquisite structural and optical characteristics of single-walled carbon nanotubes (SWCNTs), combined with the tunable specificities of proteins and peptides, can be exploited to strongly benefit technologies with applications in fields ranging from bi ...

Molecular chaperones inject energy from ATP hydrolysis into the non-equilibrium stabilisation of native proteins

Paolo De Los Rios, Alessandro Barducci, Pierre Goloubinoff, Bruno Claude Daniel Fauvet, Alberto Stefano Sassi

Protein homeostasis, namely the ensemble of cellular mechanisms collectively controlling the activity, stability and conformational states of proteins, depends on energy-consuming processes. De novo protein synthesis requires ATP hydrolysis for peptide bon ...

CO Cleavage and CO2 Functionalization under Mild Conditions by a Multimetallic CsU2 Nitride Complex

Rosario Scopelliti, Marinella Mazzanti, Lucile Sylvie Danielle Chatelain, Marta Falcone

Novel efficient chemical processes involving cheap and widely accessible carbon dioxide or carbon monoxide under mild conditions for the production of valuable chemical products are highly desirable in the current energetic context. Uranium nitride materia ...

Development of an albumin-binding ligand for prolonging the plasma half-life of peptide therapeutics

Alessandro Zorzi

Peptides represent a promising format for the development of therapeutics since they combine the advantages of proteins and small molecules. Several techniques based on rational design or in vitro evolution can be used to develop peptides as therapeutics. ...

Highly sensitive SERS analysis of the cyclic Arg-Gly-Asp peptide ligands of cells using nanogap antennas

Olivier Martin, Christian Santschi, Alejandro Ernesto Portela Otano

The cyclic RGD (cRGD) peptide ligands of cells have become widely used for treating several cancers. We report a highly sensitive analysis of c(RGDfC) using surface enhanced Raman spectroscopy (SERS) using single dimer nanogap antennas in aqueous environme ...

Molecular Level Characterization of the Structure and Interactions in Peptide-Functionalized Metal-Organic Frameworks

David Lyndon Emsley, Pierrick Berruyer

We use density functional theory, newly parameterized molecular dynamics simulations, and last generation N-15 dynamic nuclear polarization surface enhanced solid-state NMR spectroscopy (DNP SENS) to understand graft-host interactions and effects imposed b ...

Gas-phase probes of kinetically trapped peptides

Liudmila Voronina

Gas-phase techniques are promising for studying intrinsically disordered peptides and proteins, as they can be implemented in a conformer-selective way. One of the issues that prevent them from finding a broader use is the question of to which extent the s ...

Conformations of prolyl-peptide bonds in the bradykinin 1-5 fragment in solution and in the gas phase

Thomas Rizzo, Antoine Louis Claude Masson, Michael Zachary Kamrath, Liudmila Voronina, Carsten Baldauf

The dynamic nature of intrinsically disordered peptides makes them a challenge to characterize by solution-phase techniques. In order to gain insight into the relation between the disordered state and the environment, we explore the conformational space of ...

(eta(6)-Arene) ruthenium complexes with P-coordinated phosphinoferrocene amides bearing extended polar substituents at the amide nitrogen: Synthesis, characterization and cytotoxicity

Paul Joseph Dyson, Tina Riedel

Heterobimetallic Ru-Fe complexes of the general formula [(eta(6)-p-cymene) RuCl2(Ph(2)PfcCONHCH(2)CH(2-)COY-kappa P)], where Y = Me, NH2, NHEt, NHPh, and NMe2, and fc = ferrocene-1,1'-diyl, were synthesized from p-cymene ruthenium dichloride dimer and phos ...

Development of Stapling Methods by Selective Side Chain Modifications of Bioactive Peptides

Christopher Matthew Bandeli Kourra

Cyclic peptide therapeutics fill the gap between small molecules (5000 Da) as a separate class of drugs, combining the advantages of both in terms of high selectivity, bioavailability, synthetic accessibility and low toxicity. Howe ...
