      Evaluation of the lipophilicity and prediction of biological activity of some N-cyclohexyl-N-substituted-2-phenylacetamide derivatives using RP-TLC
      D. VASTAG, Nada PERISIC-JANJIC*, J. TOMIC, S. PETROVIC (*Department of Chemistry, Faculty of Sciences, University of Novi Sad, Trg D. Obradovica 3, 21000 Novi Sad, Serbia; nadap@uns.ac.rs)

      J. Planar Chromatogr. 24, 435-440 (2011). TLC of nine N-cyclohexyl-N-substituted-2-phenylacetamides on RP-18 with different aqueous eluents; water - acetone, water - acetonitrile, and water - dioxane. The volume fraction of the organic modifier in the aqueous mobile phase comprised 60-80 % (dioxane, acetone) and 70-90 % (acetonitrile) and varied in steps of 5 %. Detection under UV light at 254 nm. The effects on retention behavior of all investigated modifiers were similar. The linear relationship between retention parameters and organic modifier content allowed the extrapolation procedure. The result of the investigation showed that reversed-phase RM0 proved to express the lipophilic nature of an investigated compound as well as its biological activity.
