: In this study, the existence of biological potential of selected N-(substituted phenyl)-2-chloroacetamides was examined none empirically, as was the possibility of applying simple experimental technique in predicting essential properties which affect the biological activity of the compounds. By applying the Lipinski and Ghose's rules, it has been revealed that the examined chloroacetamides fulfill the theoretical requirements for bioactive compounds. In addition, lipophilicity was determined by applying the reversed-phase thin-layer chromatography (RPTLC18F254s) in the mixtures of water and two organic modifiers separately (methanol and acetone) and by using relevant software packages. The chromatographic retention parameters, RM0 and m, as the presumed criteria for the lipophilicity of the examined chloroacetamides were correlated by linear regression analysis, and the relevant chemometric methods (Cluster Analysis and Principal Component Analysis) with the standard measure of lipophilicity, log P, and with the selected pharmacokinetic predictors. Thus good correlations in both water-modifier systems (average correlation coefficients, r , 0.947 and 0.931) were obtained. The chemometric methods, as well as the classical correlation methods gave similar results which demonstrated that the chromatographic retention parameters, RM0 and m, can successfully describe the lipophilicity and the pharmacokinetics of the N-(substituted phenyl)-2-chloroacetamides in the first steps of preclinical research.

Lipophilicity study of selected NSAIDs, the group of the bioactive compounds usually used in humans and animals medicine, with the use of experimental and calculation methods was evaluated. LogP values are proposed and compared as descriptors of the lipophilicity of eleven compounds (from oxicams and coxibs). Obtained data were designated by thin-layer chromatography (TLC) in various chromatographic conditions, with stationary phases with different properties. The mobile phase systems were prepa...

In this study we screened twelve newly synthesised N-(substituted phenyl)-2-chloroacetamides for antimicrobial potential relying on quantitative structure-activity relationship (QSAR) analysis based on the available cheminformatics prediction models (Molinspiration, SwissADME, PreADMET, and PkcSM) and verified it through standard antimicrobial testing against Escherichia coli, Staphylococcus aureus, methicillin-resistant S. aureus (MRSA), and Candida albicans. Our compounds met all the screening...

Non-steroidal anti-inflammatory drugs (NSAIDs) are one of the most widely used classes of medicines in the treatment of inflammation, fever, and pain. However, evidence has demonstrated that these drugs can induce significant toxicity. In the search for innovative strategies to overcome NSAID-related problems, the incorporation of drugs into cyclodextrins (CDs) has demonstrated promising results. This study aims to review the impact of cyclodextrin incorporation on the biopharmaceutical and phar...

Abstract Numerous structurally different amides and imides including succinimide derivatives exhibit diverse bioactive potential. The development of new compounds requires rationalization in the design in order to provide structural changes that guarantee favorable physico-chemical properties, pharmacological activity and safety. In the present research, a comprehensive study with comparison of the chromatographic lipophilicity and other physico-chemical properties of five groups of 1-arylsuccin...

Abstract Reversed-phase thin-layer chromatography and micellar thin-layer chromatography were used in order to investigate retention behaviour and to determine lipophilicity of series of 2-(methoxy)phenylpiperazine dopamine D2 ligands with different size, shape and rigidity. The retention mechanism was discussed. The lipophilicity parameters obtained in conventional reversed-phase systems expressed as RM0 and C0, as well as RM values determined in microemulsion reversed-phase systems were correl...

Lipophilcity is an important physico-chemical parameter that influences membrane transport and binding ability to action. Migration distance following complete elution of compounds was used to calculate different lipophilicity-related parameters. The aim of this study is to show that lipophilicity is a central component of thiazole chalcones and flavonoid derivatives regarding their drug-like properties. Experimental and computational methods were used. This study considers 44 previously synthes...

It has been established that the selected acetamide derivatives fulfill Veber’s and Pardridge’s rule of good bioavailability. The lipophilicity as a crucial molecular descriptor of biological activity for acetamide derivatives was determined by reversed-phase thinlayer chromatography (RP-TLC) in different mixtures of water and organic modifiers (ethanol and tetrahydrofuran). Also, lipophilicity was examined mathematically, by using relevant software packages. The effects of the substituent on th...
