Abstract

A relaxation matrix has been calculated for a multipolar AX spin system under the on-resonance spin-locking condition. Auto- and cross-correlation terms between dipolar, quadrupolar, and CSA interactions are considered. It is shown that the spin-lock leads to many relaxation pathways being blocked, resulting in a considerably simplified relaxation network. The presence of spectral densities at zero frequency, associated with locked nuclei, allows efficient relaxation also in the absence of fast molecular motions.

Structure of the alpha-homo-DNA:RNA duplex and the function of twist and slide to catalogue nucleic acid duplexes.

High-resolution NMR studies of an alpha-homo-DNA:RNA duplex reveal the formation of a right-handed parallel-oriented helix. It differs significantly from a standard A- or B-type helix by a small twist value (26.2 degrees ), which leads to a helical pitch of 13.7 base pairs per helical turn, a negative inclination (-1.78 Angstrom) and a large x displacement (5.90 Angstrom). The rise (3.4 Angstrom) is similar to that found in B-DNA. The solution of this new helix structure has stimulated us to develop a mathematical and geometrical model based on slide and twist parameters to describe nucleic acid duplexes. All existing duplexes can be positioned within this landscape, which can be used to understand the helicalization process.

15N NMR study of substituted 2-(phenylamino)-5-phenyl-1,3,4-oxadiazoles.

Substituted 2-(phenylamino)-5-phenyl-1,3,4-oxadiazoles were studied by 15N NMR spectroscopy. All signals were assigned on the basis of HMQC and HMBC experiments. Chemical shifts values were correlated with empirical Hammett parameters as well as with calculated electron densities and chemical shieldings.

Functionalization of titanium oxide surfaces by means of poly(alkyl-phosphonates).

The use of a multiple attachment sites strategy is considered in order to improve the stability of monomolecular adlayers. The hypothesis was tested in the case of PEG-ylated compounds carrying phosphonate groups, known for their affinity toward titanium oxide surfaces. As a result, a new class of co- and terpolymers were synthesized by free-radical polymerization of three different monomers: dialkyl(methacryloyloxyalkyl)phosphonates, PEG methyl ether methacrylate, and/or butyl methacrylate monomers. Adlayers were formed following a simple dip-and-rinse protocol using diluted aqueous polymer solutions and were characterized by evaluating their thicknesses with variable angle spectroscopic ellipsometry (VASE) and their elemental compositions with X-ray photoelectron spectroscopy (XPS). The same techniques were used to determine changes of the adlayer as a function of exposure to electrolytes at different pH values and to monitor nonspecific protein adsorption upon serum exposures. The results indicated that the poly(alkyl-phosphonate)-based adlayers combine multiple site attachment of phosphonic groups and presentation of PEG side chains to the aqueous environment, resulting in both improved stability over a wide pH range in comparison to the tested reference surfaces and excellent resistance to protein adsorption when exposed to full human serum.
