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  - 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.

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.

The azo dyes were characterized by melting point, IR, UV/Vis, 1H NMR and MS data. HPLC analyses were also performed.

AB  - The chromatographic behavior of series of azo-dye derivatives has been studied by RP C-18 TLC with water-methanol, water-acetone, water-dioxane, and water-acetonitrile mobile phases. The mechanism of retention was investigated and the retention constants, R-M(0), were determined by extrapolation. Correlations between retention constants, R-M(0), and lipophificity, C-0 (C-0 = R-M(0)/m) and log P (ACD log P) were investigated. Better correlations were obtained between C-0 and log P than between R-M(0) and log P. These C-0 values may be use as a measure of the lipophilicity of the compounds investigated. The effect of mobile phase pH on retention of azo-dye derivatives was studied in RP C-18 TLC with diluted acetic acid-methanol, 20 + 30 (v/v) as mobile phase. Different methods were used to measure mobile phase pH. pK(a) values were determined on the basis of the relationships between analyte retention and mobile phase pH. Because the investigated azo dyes are newly synthesized compounds these pK(a) values have been determined for the first time. Correlations between pK(a) and log P are discussed.

AB  - The chromatographic behavior of newly synthesized uracil derivatives has been studied by normal and reversed-phase thin-layer chromatography. Benzene-methanol, benzene-acetonitrile, and benzene-isopropanol were used as mobile phases in normal-phase chromatography and water-methanol and water-acetonitrile in reversed-phase chromatography. The mechanism of retention on different TLC supports was investigated. The retention constants determined for the uracils are discussed in terms of the physicochemical properties of both the solutes and stationary and mobile phases. R-M(0) values derived by extrapolation from reversed-phase chromatography were correlated with the hydrophobicity log P calculated by use of the commercial program ACD/logP. In normal-phase chromatography values for C-0 (= R-M(0/n)) were correlated with the hydrophobicity log P. Good correlation was obtained for both types of chromatography. Retention constants R-M(0) and C-0 can be used to express the lipophilicity of the compounds investigated.

AB  - The chromatographic behavior of Para-substituted amides of alpha-phenylacetic, benzoic, propanoic, and 2,2-dimethylpropanoic acid has been studied in reversed-phase thin-layer chromatography on silica gel impregnated with paraffin oil. Mobile phases used were acetone-water, methanol-water, and dioxane-water. R-M(0) values were calculated by linear extrapolation of retention to 0% organic modifier for each mobile phase. The relationships between R-M(0) Values obtained with different organic modifiers in the mobile phases are discussed. C-0 values were obtained from the slopes and intercepts of linear relationships between retention and volume fraction of modifier. Correlation between partition coefficient, log P, and R-M(0) and between log P and C-0 was examined. Results show that C-0 is a better measure of the lipophilicity of the amides than R-M(0).

The Influence on the retention of anilide type and additional substituents in the molecule is discussed. Several chromatographic hydrophobicity parameters (CHP) have been calculated by linear correlation between log k of the investigated compounds and the concentration of methanol in the mobile phase. The chromatographic hydrophobicity parameters were compared with the log P values calculated by Rekker's fragmental method. The results show moderate correlations of CHIP with log Mus, multiple linear regressions have been applied. It was found that besides log P even the electronic effects of individual polar groups capable of hydrogen bonding proved to be very important in hydrophobic characterization of the molecule.

AB  - The retention behavior and separation ability of reversed- and normal-phase TLC with, polar and nonpolar mobile phases, has been studied by measuring the retentions of a series of amides. The retention behavior and separation ability are discussed in terms of the nature of the solute, stationary phase and eluent.
