J. of Chromatogr. B 879, 1764-1772 (2011). Quantitative structure-activity relationship (QSAR) analysis of 20 drugs with affinity for serotonin (5-HT) receptors by calculation of a set of physicochemical parameters and TLC data. TLC on silica gel and RP-2 impregnated with solutions of aspartic acid, serine, phenylalanine, tryptophan, tyrosine, asparagine, threonine and their mixtures, with two mobile phases - the systems were chosen as models of drug-5-HT-receptor interaction. The relationships between chromatographic data, molecular descriptors and biological activity data were found by regression analysis. The resulting correlations for the compounds with serotoninergic activity represent their interaction with the proposed biochromatographic models. The presented regression models based on biochromatographic studies can be an efficient tool in the QSAR analysis for initial prediction of compounds activity direction within 5-HT receptors.

J. Chromatogr. 262, 113-120 (1983). Separation performance data obtained under different conditions with a newly developed technique in the area of TLC, overpressured TLC (OPTLC). The changes in theoretical plate heights and resolution values for some lipophilic dyes were determined at different flow-rates, migration distances and layer thicknesses. Some of these data are compared with corresponding results obtained by linear high-performance TLC without pressure.

Development and systematization of nontraditional TLC methods, in which the chromatographic process occurs in a closed absorption layer on a standard TLC plate. The advantages and limitations of the methods were assessed and the expediency of their further development and wider use in practical TLC was proved.

HPTLC of polycyclic aromatic hydrocarbons on different stationary phases with various mobile phases in several development modes, conventional, continuous, and multiple development. Reversed-phases in separation using RP-18 silica and methanol - water or methanol - water based ternary solvent system gave the best result.
