A novel liquid crystalline system for partial alignment of polar organic molecules

Klochkov V.; Klochkov A.; Thiele C.; Berger S. (2006)

A new system for partial alignment of polar organic molecules to measure residual dipolar couplings in NMR consists of a 1:1 or a 2:1 mixture of water and DMSO including 3-13% n-alkylpentaethylene glycol as the surfactant. ...
Detailed NOESY/T-ROESY analysis as an effective method for eliminating spin diffusion from 2D NOE spectra of small flexible molecules

Efimov S.; Khodov I.; Ratkova E.; Kiselev M.; Berger S.; Klochkov V. (2016)

© 2015 Elsevier B.V. An intriguing property of the multistep magnetization transfer, so-called spin diffusion, is that it can affect the results of NMR-based analysis of conformer distribution of small molecules in solution. ...
Geometric structure of 2-phenyl-1,3-dithia-5,6-benzocycloheptene 1-oxide

Klochkov V.; Khairutdinov B.; Shaikhutdinov R.; Findaisen M.; Berger S. (2001)

Two-dimensional nuclear Overhauser effect spectroscopy (2D NOESY) was used to determine proton-proton distances for the chair conformer of 2-phenyl-1,3-dithia-5,6-benzocycloheptene 1-oxide in CD2Cl2 in the system CS2-CDCl3. ...
Separation of Cross-Relaxation and Exchange in Two-Site Spin Systems with Weak Spin-Spin Couplings

Klochkov V.; Shaikhutdinov R.; Khairutdinov B.; Klimovitskii E.; Findeisen M.; Berger S. (2003)

A ratio relating the cross-relaxation rates, rate constants, and cross-peak and diagonal peak integrals is used for the analysis of exchanging two-site spin systems with weak scalar spin-spin couplings to extract the rate ...
Spatial structure of cyclosporin A and insight into its flexibility

Efimov S.; Karataeva F.; Aganov A.; Berger S.; Klochkov V. (2013)

The molecule of immunosuppressant drug cyclosporin A (CsA) exhibits different properties when dissolved in different media. In apolar solvents it is stabilized by intramolecular hydrogen bonds, but there also exist some ...
Spatial structure of peptides determined by residual dipolar couplings analysis

Klochkov V.; Baikeev R.; Skirda V.; Klochkov A.; Muhamadiev F.; Baskyr I.; Berger S. (2009)

The gated decoupled 13C NMR spectra of a dipeptide (Glu-Trp) and a tetrapeptide (NAc-Ser-Phe-Val-Gly-OMe) were recorded in D2O and in a lyotropic alignment medium (pentaethylene glycol monododecyl ether/n-hexanol). The ...
Spatial structure of tetrapeptide N-AC-Ser-Phe-Val-Gly-OMe in "protein-micelle of sodium dodecyl sulfate" complex and in solid state by NMR spectroscopy

Blokhin D.; Berger S.; Klochkov V. (2013)

In the present paper the applicability of a structure determination for a four amino acid residues containing oligopeptide N-Ac-Ser-Phe-Val-Gly-OMe was investigated. The spatial structure of the "tetrapeptide (N-Ac-Ser-P ...
The use of a lyotropic liquid-crystalline medium and residual dipolar coupling constants for determination of the spatial structure of thiacalix[4]arenes in solutions

Klochkov V.; Khairutdinov B.; Klochkov A.; Tagirov M.; Thiele C.; Berger S.; Vershinina I.; Stoikov I.; Antipin I.; Konovalov A. (2004)

The possibility of using an approach for the elucidation of the spatial structure of functionalized thiacalix[4]arenes based on the determination the residual dipolar coupling constants between the 1H and 13C nuclei separated ...
