Phage Selection of Bicyclic Peptide Ligands of the Notch1 Receptor

Freddy Radtke, Christian Heinis, Charlotte Marie Urech-Varenne

Precise regulation of the Notch signaling pathway is crucial, as increases or deficiencies in signaling are associated with diseases, including a wide range of cancers. Recent studies have demonstrated that monoclonal antibodies that bind and stabilize the ...

Gd(DOTAlaP): Exploring the Boundaries of Fast Water Exchange in Gadolinium-Based Magnetic Resonance Imaging Contrast Agents

Lothar Helm, Shima Karimi

Here, we describe the synthesis of the single amino acid chelator DOTAlaP and four of its derivatives. The corresponding gadolinium(III) complexes were investigated for their kinetic inertness, relaxometric properties at a range of fields and temperatures, ...

Hsp70 chaperones are non-equilibrium machines that achieve ultra-affinity by energy consumption

Paolo De Los Rios, Alessandro Barducci

70-kDa Heat shock proteins are ATP-driven molecular chaperones that perform a myriad of essential cellular tasks. Although structural and biochemical studies have shed some light on their functional mechanism, the fundamental issue of the role of energy co ...

Vibrationally Promoted Dissociation of Water on Ni(111)

Rainer Beck, Phil Morten Hundt

Water dissociation on transition-metal catalysts is an important step in steam reforming and the water-gas shift reaction. To probe the effect of translational and vibrational activation on this important heterogeneous reaction, we performed state-resolved ...

Lanthanide Complexes Based on beta-Diketonates and a Tetradentate Chromophore Highly Luminescent as Powders and in Polymers

Marinella Mazzanti

A new type of octacoordinated ternary β-diketonates complexes of terbium and europium has been prepared using the anionic tetradentate terpyridine-carboxylate ligand (L) as a sensitizer of lanthanide luminescence in combination with two β-diketonates ligan ...

On the Nature of Interactions of Radicals with Polar Molecules

Jeremy Samuel Arey, Peter Rudolf Tentscher

Solvated radicals play an important role in many areas of chemistry, but to date, the nature of their interactions with polar solvent molecules lacks chemical interpretation. We present a computational quantum chemical analysis of the binding motives of bi ...

Self-assembly of highly luminescent lanthanide complexes promoted by pyridine-tetrazolate ligands

Marinella Mazzanti

Two tridentate pyridine-tetrazolate ligands (H 2pytz and H 2pytzc), analogues of the well-known dipicolinate (H 2dpa) ligand, have been synthesized in a straightforward manner and used for lanthanide(iii) coordination. The structures of the resulting tris- ...

Boosting the Sensitivity of Ligand-Protein Screening by NMR of Long-Lived States

Geoffrey Bodenhausen, Christian Heinis, Aurélien Bornet, Inmaculada Rentero Rebollo, Alessandro Angelini, Simone Ulzega, Nicola Salvi, Roberto Buratto

A new NMR method for the study of ligand protein interactions exploits the unusual lifetimes of long-lived states (LLSs). The new method provides better contrast between bound and free ligands and requires a protein-ligand ratio ca. 25 times lower than for ...

Improving the study of proton transfers between amino acid side chains in solution: choosing appropriate DFT functionals and avoiding hidden pitfalls

Marta Andreia Da Silva Perez

We have studied the influence of implicit solvent models, inclusion of explicit water molecules, inclusion of vibrational effects, and density functionals on the quality of the predicted pK a of small amino acid side chain models. We found that the inclusi ...

Femtosecond UV Studies of the Electronic Relaxation Processes in Cytochrome c

Majed Chergui, Andrea Cannizzo, Cristina Consani

We report on an experimental study with UV and visible ultrafast time-gated emission and transient absorption of the early photodynamics of horse heart Cytochrome c in both ferric and ferrous redox states. A clear separation in time and energy of tryptopha ...
