J. Planar Chromatogr. 10, 441-446 (1997). Determination of lipophilicity and specific hydrophobic surface of 11 sulfosuccinic acid esters by RP TLC in ion-free eluents and in eluents containing NaCl, KCl, MgCl2, and CaCl2. The strength and selectivity of the effect of salts were separated by use of the spectral mapping technique. Stepwise regression analysis was used to elucidate the relationship between the retention characteristics and the physicochemical parameters.

J. Planar Chromatogr. 12, 408-415 (1999). Investigation of the influence of a perpendicular homogeneous electric field on the TLC process for four different sorbents, SiO2, Al2O3, cellulose and polyamide; description of the influence on mobile phase migration time, on chromatographic parameters, and on the properties of the sorbent layers developed with monocomponent mobile phase, from apolar solvents such as hexane and heptane to strong polar phases such as methanol, formamide and water, using two substance groups as samples - inactive compounds (polycyclic hydrocarbons) and substances with active substituents (quinoline derivatives).

J. Planar Chromatogr. 14, 439-444 (2001). After separation of homologous series of higher fatty acids, higher alcohols, and methyl esters of higher fatty acids the RM values and the partition coefficients could be correlated with numerical values of topological indexes based on the adjacency matrix and on the distance matrix. Partition TLC of lauric, myristic, palmitic, stearic acid, and the corresponding alcohols and methyl esters on kieselguhr impregnated with a 10% or 15% solution of paraffin oil in hexane with methanol - water 9:1 and ethanol - water 9:1. Visualization by spraying with bromothymol blue or with a 0.005% aqueous solution of new fuchsin.

Part II. J. Chromatogr. A 1007 (1-2), 157-164 (2003). Quantitative structure–activity relationship (QSAR) analysis of H1-antihistamine activity was carried out and chromatographic data of 2-[2-(phenylamino)thiazol-4-yl]ethanamine, 2-(2-benzyl-4-thiazolyl)ethanamine, 2-(2-benzhydrylthiazol-4-yl)ethylamine derivative, and 2-(1-piperazinyl- and 2-(hexahydro-1H-1,4-diazepin-1-yl)benzothiazole derivatives were obtained. Silica gel impregnated with solutions of selected amino acid mixtures (-Asp, Asn, -Thr and -Lys) were used in two developing solvents as human histamine H1-receptor (hH1R) antagonistic interaction models. Lipophilicity data of the examined compounds were obtained and used in the QSAR assay. Using regression analysis, relationships between chromatographic and biological activity data were found. The correlations obtained in the present experiment with NP-TLC are more significant that those obtained in the experiment with RP2-TLC because of the optimal fitting of the chromatographic system conditions to the lipophilicity of solutes. All proposed chromatographic models should facilitate pre-selection of the new drug candidates. The correlations of calculated pA2(H1) values of the tested compounds predicted by the use of the best equations versus their pA2(H1) obtained from the biological tests were significant (R2= 0.91-0.94).

TLC of acylanilide derivatives on TLC aluminum foil with acetone - water and methanol - water mixtures. The hRf values related to the molecular lipophilicity and to the specific hydrophobic surface area of the analytes were calculated.

HPTLC of new derivatives of 1,2,4-triazole and thiosemicarbazide on RP-18W with 30 % acetonitrile and 40 % MeOH as organic modifiers, both in water, detection at UV 254 nm. 30 % provided the most close phase ratio in TLC and HPLC. The method can be used as a pilot technique for the anticipation of retention in HPLC.

HPTLC of newly synthesized cycloalkylspiro-5-hydantoins (derivates of 3-(4-substituted benzyl)-cyclopentanespiro-5-hydantoin, 3-(4-substituted benzyl)-cyclohexanespiro-5-hydantoin, and 3-(4-substituted benzyl)-_x000D_cycloheptanespiro-5-hydantoin) on RP-18 with varying content of methanol 50–90%. Multivariate analysis enabled the classification of the lipophilicity and structural properties of the investigated compounds.
