J. Liq. Chromatogr. Relat. Technol. 43, 925-933 (2020). HPTLC of 21 cycloalkylspiro-5-hydantoins on RP-18 with mixtures of water and organic solvent (acetone: 0.5-0.8 v/v, 1,4-dioxane: 0.5-0.74 v/v, tetrahydrofuran: 0.4-0.7 v/v, acetonitrile: 0.5-0.7 v/v). Detection at UV 254 nm. The logarithm of partition coefficient, log P, for the investigated compounds was calculated. Multivariate data analysis (hierarchical cluster analysis (HCA) and principal component analysis (PCA) was performed.
J. Liq. Chromatogr. Relat. Technol. 43, 852-862 (2020). HPTLC of diphenylacetamide derivatives on RP-18 with binary mixtures of organic modifier (ethanol, n-propanol, tetrahydrofuran and acetonitrile 36–52 % with 4 % increments). Detection at UV 254 nm. Lipophilicity of examined derivatives was determined. Two multivariate methods, Cluster Analysis, (CA) and Principal Component Analysis, (PCA) were performed to study the compliance of the chromatographic parameters, the standard measure of lipophilicity, the pharmacokinetic predictors and the toxicity parameters of the substances.
J. Liq. Chromatogr. Relat. Technol. 43, 580-588 (2020). Retardation factor (hRF) of 42 amino acids in two different eluents (acetonitrile - sodium azide and 1,2 dioxane-sodium azide solutions) were predicted by different quantitative structure-retention relationship (QSRR) methods. The method analyzed the effect of sum of geometrical distances between N and O in separation of amino acids in RP-TLC.
J. Planar Chromatogr. 33, 245-253 (2020). HPTLC of twenty-one chalcones on RP-18 with three binary combinations (acetonitrile - water, ethanol - water and acetone - water) in the following compositions: 1:1, 3:2, 7:3 and 4:1. Detection at UV 254 nm. Acetonitrile - water was found to be the most suitable system for lipophilicity prediction of tested compounds using calculated logP values. Quantitative structure-retention relationship (QSRR) analysis was performed to identify the most important structural and physico-chemical properties that influence retention behavior of tested compounds.
J. Liq. Chromatogr. Relat. Technol. 43, 328-335 (2020). HPTLC of verapamil, diltiazem, ivabradine, and its related analogs on silica gel with acetonitrile - methanol (acidified with 25 % formic acid) with the following volume fraction of methanol: 0.25, 0.20, 0.15, 0.13 and 0.10. Detection under UV 254 nm. Retention behavior was investigated and quantitative structure retention relationship (QSRR) modeling was performed with the use of the stepwise multiple linear regression.
J. Liq. Chromatogr. Relat. Technol. 42, 563-569 (2019). TLC of 17 new anti-proliferative and antiinflammatory tetracyclic 6-substituted 9-fluoroquinobenzothiazines on RP-18 with acetone - aqueous TRIS (tris(hydroxymethyl)-aminomethane) buffer pH 7.4 (ionic strength 0.2 M), where the concentration of acetone was from 50 to 85 % in 5 % increments. Lipophilicity parameters were determined (RM0 and logPTLC) and compared with computationally calculated lipophilic parameters. Relation of lipophilicity with predicted and experimental biological activities was discussed.
J. Planar Chromatogr. 32, 517-520 (2019). HPTLC of tramadol (1), caffeine (2), paracetamol (3), ibuprofen (4), naproxen (5), and diclofenac (6) on RP-18 WF, LiChrospher RP-18 WF, and RP-18 WF with concentration zone, developed with various ratios of methanol in water with 0.1 M potassium chloride. Qualitative identification under UV light at 254 nm. Potassium chloride may be used to suppress ion–ion interactions between the solutes and the silica gel surface. HPTLC RP-18WF plates with concentration zone and developed with methanol - water 13:7 with addition of 0.15 mol/L KCl were suitable for the qualitative and quantitative analyses of tramadol, paracetamol, caffeine, naproxen, and ibuprofen or diclofenac. The method allowed to study subtle differences in the efficiency of the separation of analgesic drugs by HPTLC with similar octadecyl silica-based adsorbents.
J. Planar Chromatogr. 32, 265-271 (2019). HPTLC of 24 anions on tri-n-butyl amine (TBA) impregnated silica gel with 13 mobile phases (methanol, dimethylformamide, diisopropyl ether, tetrahydrofuran, 2-propanol, dimethylformamide - methanol 1:1, dimethylformamide - diisopropyl ether 1:1, dimethylformamide - tetrahydrofuran, 1:1, dimethylformamide - 2-propanol 1:1, 0.1 M oxalic acid, 0.1 M tartaric acid, 0.1 M citric acid and 0.1 M succinic acid). The retention behavior was analyzed in aqueous and non-aqueous mobile phases. The hRF values were also correlated with their lyotropic numbers. 20 % TBA-impregnated silica gel was found very effective for binary and ternary separations of anions.
