Genetically encoded fluorescent sensor proteins offer the possibility to probe the concentration of key metabolites in living cells. The approaches currently used to generate Such fluorescent sensor proteins lack. generality, as they require a protein that ...
Six diiodido-diamine platinum(II) complexes, either cis or trans configured, were prepared, differing only in the nature of the amine ligand (isopropylamine, dimethylamine, or methylamine), and their antiproliferative properties were evaluated against a pa ...
Mn2+ complexes represent an alternative to Gd3+ chelates which are widely used contrast agents in magnetic resonance imaging. In this perspective, the authors studied the Mn2+ complexes of two 12-membered, pyridine-contg. macrocyclic ligands bearing one pe ...
alpha-D-Galactosyl)phenylmethane (1). (alpha- and beta-D-galactosyl)-(difluoro)phenylmethane (2 and 3) have been prepared and their conformations in solution were described by using a combination of force-field calculations and NMR spectroscopic studies. G ...
The design of efficient ligands remains a key challenge in drug discovery. In the quest for lead-like ligands for the FK506-binding protein 51 (FKBP51), we designed two new classes of bicyclic sulfonamides to probe the contribution of conformational energy ...
Previous state-selected spectra of methanol in the 5ν1 OH stretch overtone region [O. V. Boyarkin, T. R. Rizzo, and D. S. Perry, J. Chem. Phys. 110 (23), 11346 (1999)] revealed structure indicating intramolecular vibrational redistribution (IVR) on three t ...
The labile cobalt (II) complex [Co(TUF)2(Pic)2] with 4,4,4-trifluoro-1-(2-thienyl)-1,3-butanedione (TUF) bidentate and 4-methylpyridine (Pic) monodentate ligands was studied by variable temp. (VT) 19F NMR from 184 to 312 K. In contrast to the solid state, ...
This thesis is concerned with supramolecular architectures assembled at metal surfaces. The investigations pursued two objectives. On the one hand, the focus was placed on the fabrication of low-dimensional surface-supported network structures by applying ...
The Pb and Cd binding capacity of alginates were quantified by the determination of their complex stability constants and the concentration of complexing sites using H+,Pb 2+,orCd2+ selective electrodes in both static and dynamic titrations. Centrifugation ...
A diastereoselective three-component synthesis of chiral 2-(1,2-diaminoalkyl)phenols from an electron-rich phenol, an amine, and a chiral alpha -N,N-dibenzylamino aldehyde is developed. The diastereoselectivity of this phenolic Mannich reaction is temp.-de ...
