Publikováno v: Journal of Biomolecular Structure and Dynamics. 15:967-985

In this paper we examine the interactions of Calf Thymus DNA and the model polynucleotides poly(dA).poly(dT), poly(dAdT)2 and poly(dG.dC)2 with a group of metallopor- phyrins derived from the freebase porphyrin tetrakis(4-N-methylpyridyl)porphine, H2

Internal DNA Modes Below 25 cm−1: A Resonance Raman Spectroscopy Observation

Autor: Vladimir Lisy, L. Chinsky, P. Miskovsky, B. Brutovsky

Publikováno v: Journal of Biomolecular Structure and Dynamics. 14:517-523

The first resonance Raman scattering observation of the low-frequency (LF) region (below 40 up to 12 cm-1) of DNA motions is presented. Since the concentration of the studied DNA solution was very low (1 mg/ml), the spectra features reflect internal

Genetic refinement of the molecular force field: Normal mode analysis of purine vibrations

Autor: Pavol Miškovský, L. Chinsky, B. Brutovský, V. Lisý, Jozef Uličný

Publikováno v: Biospectroscopy. 3:61-71

A new approach to the empirical force field determination by the adaptive optimization method is studied. The problem is conceived as a multiparameter optimization task and solved by the genetic algorithms (GA). The principles of the approach and the

Hypericin-Induced Cell Photosensitization Involves an Intracellular pH Decrease

Autor: P. Miskovsky, Pierre-Yves Turpin, and L. Chinsky, Franck Sureau

Publikováno v: Journal of the American Chemical Society. 118:9484-9487

Snarf-1-AM (Seminaphthorhodafluor-1-acetoxymethylester) being used as a fluorescent pH probe, confocal laser microspectrofluorometric measurements allowed intracellular pH to be assessed within 3T3 mouse fibroblasts in the presence or in the absence

Publikováno v: Journal of Biomolecular Structure and Dynamics. 13:547-552

Summary Interactions of the antiretroviral hypericin molecule with polynucleotides, i.e. poly(dG-dC), poly(dA-dT), poly(rG) and poly(rC), have been studied in aqueous solutions by resonance Raman spectroscopy, using an UV excitation wavelength which

Publikováno v: Journal of Molecular Structure. 355:147-158

Resonance Raman spectra for purine and its deuterated analogues were recorded with excitation at 280, 257 and 222 nm. These were compared with the Fourier transform-Raman (FT-R) spectra in aqueous solution recorded with excitation at 1064 nm. The cha

UV resonance Raman contribution to structure determination of the X form of double-stranded poly(dA-dT)

Publikováno v: Journal of Molecular Structure. 344:11-20

Double-stranded poly(dA-dT) in aqueous solution and in the presence of a sufficient amount of a water soluble porphyrin (i.e. Cu(TMpy-P4)) can adopt a structure different from all canonical A-, B- and Z-DNA conformations. The corresponding circular d
