AB  - Biological activity of a molecule is closely related to its lipophilicity. This significant parameter was determined for a group of potentially bioactive N-(4-phenylmonosubstituted)-2-cyanoacetamides applying thin-layer chromatography on reversed phase (RP-TLC) in mixtures of water and two organic modifiers separately, i-propanol and dioxane. The effect of the chemical structure of derivatives and the influence of the applied organic modifier on their retention were studied. The determined chromatographic retention constants, R-M(0), and the chromatographic parameter, m, of compounds were correlated with software calculated partition coefficients, log P as the standard measure of lipophilicity and with different pharmacokinetic predictors applying classical linear and multiple regression analysis. By classical linear regression analysis in both water-modifier systems only R-M(0)-log P and m-log P correlations were established (average r, 0.909 and 0.826). All studied relationships were enhanced by molecular descriptors that fulfilled the modified Lipinski's rule of five. Thereby, the performed multiple regression analysis gave better correlations (for R-M(0)-log P and m-log P average r(2), 0.994 and 0.993; for R-M(0)-pharmacokinetic parameters and m-pharmacokinetic parameters average r(2) 0.978 and 0.980). The obtained results indicate that the chromatographic parameters, R-M(0) and m determined by RP-TLC at given conditions could be used successfully for the description of lipophilicity and the evaluation of pharmacokinetic properties of N-(4-phenylmonosubstituted)-2-cyanoacetamides as potential bioactive molecules.

AB  - The selected diphenylacetamide derivatives were subjected to chromatographic and in silico approach in order to obtain significant information about their structure-activity relationships. As an early step in the assessment of their biological profile, drug-likeness and lead-likeness rules were performed, as well as determination of the bioactivity scores. The relationships between the obtained chromatographic parameters and the relevant software lipophilicity/pharmacokinetic/toxicity predictors of the studied derivatives were examined by linear regression and multivariate methods. Beside the satisfactory linear relationships obtained for each applied system, the multivariate methods gave more concrete relations between the analyzed parameters of biological activity. Higher similarity between the chromatographic parameters (R (M) (0), C (0)), standard measure of lipophilicity and pharmacokinetic predictors was confirmed, while the chromatographic parameter m obtained in the same conditions exhibits better agreement with the bioactivity scores and toxicity parameters. Also, it was observed that the values of diphenylacetamide's biological activity parameters are in the greatest extent conditioned by the polarity of the substituent presented in its molecule.

AB  - Carbohydrazones are compounds that are increasingly studied due to their wide potential biological activity. Monocarbohydrazones (mCHs), as one of the carbohydrazone derivatives, so far have been poorly investigated. For a more detailed study, in this paper, eighteen compounds of monocarbohydrazones (eight known and ten newly synthesized derivatives) were synthesized and characterized using NMR and IR spectroscopy. As carbohydrazones show E/Z isomerization caused by the presence of the imino group, some of the synthesized mCHs are in the form of a mixture of these two isomers. The effects of specific and nonspecific solvent-solute interactions on the UV absorption maxima shifts were evaluated using linear free energy relationships principles, i.e., using Kamlet-Taft's and Catalan's models. For more information about interactions between dissolved substance and the surrounding medium, correlations have been made with Hansen's solubility parameters. The influence of the structure on the spectral behavior of the compounds tested was interpreted using Hammett's equation. Experimentally obtained physicochemical properties of mCHs were compared to and confirmed with computational methods that included TD-DFT calculations and MP2 geometry optimizations. Graphic abstract

AB  - Selected chemometric methods were used to form models that define the qualitative and quantitative dependence between the chemical structure and the parameters of potential biological activity (lipophilicity, retention, pharmacokinetic, and toxic properties) of the selected diphenylacetamide derivatives. The chromatographic retention parameters of the selected diphenylacetamides were determined by applying reversed-phase thin-layer chromatography (RPTLC) on C18 and cyano modified carriers in mixtures of water-methanol and water-acetone. It was found that the polarity of the substituent R has dominant influence and its electronic effects to a lesser extent, on the studied parameters of the biological activity of diphenylacetamides. Also, results suggest a better similarity of the retention constants, R-M(0), with parameters of lipophilicity and pharmacokinetic predictors. Contrary to that, chromatographic parameter, m, exhibits a greater resemblance with toxicity parameters.

AB  - The UV absorption spectra of twelve N-(substituted phenyl)-2-chloroacetamides were recorded in eighteen solvents. The effect of specific and non-specific solvent-solute interactions on the absorption maxima shifts was evaluated by using the Kamlet-Taft solvent parameter set, i.e. applying linear solvation energy relationships (LSER) principles. Optimized geometries and experimental results were interpreted by using DFT (B3LYP/6-311+G(d,p) method) and time-dependent density functional (TD-DFT) method. Overall electron density in both ground and excited state was obtained by the use of Quantum Theory of Atoms in Molecules, i.e. Bader's analysis. It was found that both solvent and substituents cause appropriate change of the extent of conjugation in the molecules that further affect their intra-molecular charge transfer (ICT) character. Linear free energy relationships (LFERs) were applied to the substituent-induced NMR chemical shifts (SCS) using single substituent parameter (SSP) and dual substituent parameter (DSP) model. Transmission mode of the electronic effects of substituent was discussed according to the results of theoretical calculations and results of LFER correlations. Comparative analysis of presented results with the ones published for structurally similar series of amide which contained cyano group, instead chlorine, provides additional information on the impact of present group to the properties of investigated compound.

AB  - A series of sixteen synthesized thiouracil azo dyes was obtained by condensation of arylazo acetoacetic esters with thiourea. Purified products were characterized by UV-Vis, FT-IR, H-1 and C-13 NMR spectroscopy. The UV-Vis absorption spectra of all synthesized compounds were recorded in nineteen solvents of different properties. The study and analysis of the spectral data of azo dyes generally indicate that the tautomeric equilibrium is shifted to the hydrazone tautomeric form in the solid state. Linear solvation energy relationships describe solvent influence on solvatochromism of the hydrazone form with the use of the Catalan model. Linear free energy relationships were applied in the form of single substituent parameter model to analyze substituent electronic effects on the spectral behavior of the compounds by Hammett's equation. The correlations obtained with aid of theoretical calculations give insight into the influence of molecular conformation on the transmission of substituent effects, as well as different solvent-solute interactions.

AB  - Modeling properties of newly synthesized compounds is important for both understanding their activity and predicting their interactions. This paper describes the evaluation of the lipophilicity of the newly synthesized cycloalkylspiro-5-hydantoins by experimental and calculation methods. The chromatographic lipophilicity (R-M(0)) of the analyzed compounds was determined by reversed-phase liquid chromatographic system consisting of RP-18 stationary phase and methanol-water mobile phase. Correlation coefficients between R-M(0) values and the predicted log P were above 0.93, indicating a strong linear relationship between the variables. Multivariate data analysis applied in this study enabled the comparison of the lipophilicity and the structure of the investigated compounds using solely information obtained from thin-layer chromatography. Hierarchical clustering analysis (HCA) reveals a high similarity between R-M(0) and miLogP whereas squared log Ps such as ALOGP2 and MLOGP2 were distinct from R-M(0). HCA classifies the investigated compounds into three clusters according to lipophilicity. Principal component analysis (PCA) yields two principal components which explained  gt 99.19% total variance. The changes in the lipophilicity of the substituents attached in the molecule are reflected in the value of PCs. An increase in the lipophilicity of spiro substituent results in a decrease of values of both PC1 and PC2. The increase in the lipophilicity of R substituent decreases the value of PC1 and increases the value of PC2. The positive value of PC1 is typical for the compounds with the electron withdrawing groups such as CN, NO2, or OCH3.

abstract = "Modeling properties of newly synthesized compounds is important for both understanding their activity and predicting their interactions. This paper describes the evaluation of the lipophilicity of the newly synthesized cycloalkylspiro-5-hydantoins by experimental and calculation methods. The chromatographic lipophilicity (R-M(0)) of the analyzed compounds was determined by reversed-phase liquid chromatographic system consisting of RP-18 stationary phase and methanol-water mobile phase. Correlation coefficients between R-M(0) values and the predicted log P were above 0.93, indicating a strong linear relationship between the variables. Multivariate data analysis applied in this study enabled the comparison of the lipophilicity and the structure of the investigated compounds using solely information obtained from thin-layer chromatography. Hierarchical clustering analysis (HCA) reveals a high similarity between R-M(0) and miLogP whereas squared log Ps such as ALOGP2 and MLOGP2 were distinct from R-M(0). HCA classifies the investigated compounds into three clusters according to lipophilicity. Principal component analysis (PCA) yields two principal components which explained  gt 99.19% total variance. The changes in the lipophilicity of the substituents attached in the molecule are reflected in the value of PCs. An increase in the lipophilicity of spiro substituent results in a decrease of values of both PC1 and PC2. The increase in the lipophilicity of R substituent decreases the value of PC1 and increases the value of PC2. The positive value of PC1 is typical for the compounds with the electron withdrawing groups such as CN, NO2, or OCH3.",

AB  - Amide derivates are biologically active compounds and they are widely used in all spheres of life. Therefore, it is very important to know their physical-chemical properties. In this work the influence of characteristics and nature of the solvent on the absorption spectra of N-aryl-phenylacetamide was investigated, in order to obtain information about their solvatochromic properties. The spectra of the compounds were recorded in 15 solvents, with different properties, in the wavelength range from 200 to 400 nm. The effect of the solvents on the absorption spectra of N-aryl-phenylacetamide was analyzed by using Kamlet-Taft's solvatochromic model. Also, in order to obtain detailed information on the type and dominance of the interactions that occur between the compound and the surrounding medium, correlations were made with absorption maxima and Hansen's solvent parameters. In addition to the effect of solvent, the impact of the chemical structure on the spectral behavior of tested amide derivatives was analyzed.

AB  - The lipophilicity of the newly synthesized N-(substituted phenyl)-2-chloroacetamides, as the most commonly used molecular descriptor of a potential biological activity was the subject of research. The lipophilicity of the tested derivatives was determined by applying the reversed-phase thin-layer chromatography (RPTLC18F254s) in mixtures of water and one protic (n-propanol) and one aprotic (acetonitrile) solvent, as well as mathematically. The effects of the substituent on the lipophilicity of chloroacetamides were discussed. The obtained chromatographic retention constant, R-M(0), of examined chloroacetamides was correlated with the standard measure of lipophilicity, log P, and with pharmacokinetic predictors such as human effective permeability in jejunum, P-eff, plasma protein binding, PPB, and distribution through blood-brain barrier, log BBB, using linear regression analysis and two multivariate methods, cluster analysis and principal component analysis. All the applied methods gave very similar results, and all the procedures also confirmed the fact that R-M(0) determined by RPTLC could be used as a descriptor to estimate the potential biological activity of N-(substituted phenyl)-2-chloroacetamides.

AB  - Lipophilicity, a very important parameter in the potential biological activities of molecules, was investigated for newly synthesized N-substituted-2-phenylacetamide derivatives. The determination was carried out in two ways: first experimentally, by applying thin-layer chromatography (TLC) on reversed-phase TLC (RPTLC) RP18F254s in the presence of one protic (methanol) and one aprotic solvent (acetonitrile) and then mathematically, by using different software packages. The intercept of the linear dependence between volume fractions of the organic solvent and the retention parameters obtained by TLC is known as the retention chromatographic constant, R-M(0), while the slope represents the m value. In order to establish the dependences between the partition coefficient, log P as the standard measure of lipophilicity and the alternative lipophilic parameters obtained experimentally by TLC, R-M(0) and m values, linear regression analysis and multivariate methods, cluster analysis (CA) and principal component analysis (PCA), were used. All applied methods gave approximately similar results. Although there is a linear dependence between the two chromatographic parameters, the retention constant, R-M(0), and the m values, only R-M(0) shows suitable similarity with the standard measure of lipophilicity of the investigated N-substituted-2-phenylacetamide derivatives at the given conditions. The existence of this resemblance proves that the chromatographic retention constant, R-M(0), obtained by RPTLC could be successfully used for the description of lipophilicity of investigated compounds. On the other hand, the results confirmed that the applied linear regression analysis and the multivariate analysis (CA and PCA) have the ability to compare lipophilic parameters of the investigated phenylacetamide derivatives obtained in different ways.

AB  - UV absorption spectra of N-(substituted phenyl)-2-cyanoacetamides have been recorded in the range 200-400 nm in the set of selected solvents. The solute-solvent interactions were analyzed on the basis of linear solvation energy relationships (LSER) concept proposed by Kamlet and Taft. The effects of substituents on the absorption spectra were interpreted by correlation of absorption frequencies with Hammett substituent constant, sigma. It was found that substituents significantly change the extent of conjugation. Furthermore, the experimental findings were interpreted with the aid of ab initio B3LYP/6-311G(d,p) method. Electronic energies was calculated by the use of 6-311++G(3df,3pd) methods with standard polarized continuum model (PCM) for inclusion of the solvent effect.

AB  - The potential biological activity of a molecule largely depends on its lipophilicity. The lipophilicity of derivatives of N-substituted-2-phenylacetamide was investigated experimentally, by applying thin-layer chromatography on reversed phase (RP-TLC on RP 18 F-254s) in the presence of ethanol and dioxane and by using relevant software packages. In order to establish dependence between lipophilicity obtained in different ways, linear regression analysis and multivariate methods were used. Approximately similar groupings of lipophilic parameters and tested compounds were registered in case of both chemometric methods. The obtained results confirm the fact that the applied linear regression analysis and multivariate analysis provide opportunities for comparing chromatographic retention data and lipophilic parameters of the investigated phenylacetamide derivatives. Results suggest that the lipophilicity of investigated molecules largely depends on the nature of the substituents linked to nitrogen atom and on the other hand that the chromatographic retention constants, R-M(0), determined by RP-TLC method, are similar to the standard measure of lipophilicity, log P, which makes this method appropriate for predicting lipophilicity.

AB  - Retention behavior of some N-(4-phenylsubstituted)-2,3-diphenylpropanamides was investigated on reversed phase thin layer chromatography (RP-C18). Retention constants of investigated compounds were determined in the following solvent systems: water-ethanol, watern-propanol and water-i-propanol. Linear relationships were obtained between retention, RM and volume fraction of organic solvent, ϕ. As a measure of lipophilicity of tested propanamides, Hansch`s lipophilicity parameter, π, were calculated. Chromatography retention constants RM0 were correlated with Hansch`s lipophilicity parameter, and good linear relationships were obtained. These results confirm, that retention constants, (RM0 ), determined in reversed phase thin-layer chromatography (RP-TCL) can be used, as criteria of lipophilicity.

AB  - The chromatographic behavior of N-cyclohexyl-N-substituted-2-phenylacetamides was investigated using reversed phase thin-layer chromatography (RP-TLC). RP-TLC was performed on a C-18 bonded phase with different aqueous eluents: water-acetone, water-acetonitrile and water dioxane. Linear relationship between retention parameters and organic modifier content in the mobile phase allows the extrapolation procedure. From results, it is evident that retention behavior of investigated compound depended on structures of substituents R. The correlation between the chromatographic lipophilic parameters (R-M(0)) and calculated log P values and several pharmacokinetics parameters such as HIA (human intestinal absorption) predictor, the plasma protein binding (PB) predictor, and partition predictor for predicting the biological activity of the blood-brain barrier (BBB) has been studied. The results show that reversed-phase R-M(0) proved to express lipophilic nature of investigated compounds as well as biological activity.

AB  - The chromatographic behavior of some N,N-disubstituted-2-phenylacetamide derivatives has been studied on the chemically bonded stationary phase RP-C-18 with acetone, acetonitrile, tetrahydrofuran, dioxane, methanol, ethanol, 1-propanol, and 2-propanol as organic modifiers of aqueous mobile phases. The retention observed with different mobile-phase modifiers was correlated. The effects of different physicochemical properties of the compounds on retention behavior when chromatographed with aqueous mobile phases containing protic and aprotic modifiers were also studied. Multiple linear regression analysis was used to correlate chromatographic retention constants of the compounds with physicochemical properties. The chromatographic lipophilicity R-M(0) (determined by linear extrapolation) was correlated with log P values calculated by use of different theoretical methods. Good relationships were obtained for all the systems investigated. Good correlation was obtained between lipophilicity measured chromatographically and biological activity predictors.
