      Normal and reversed phase thin layer chromatography data in quantitative structure-activity relationship study of compounds with affinity for serotonin (5-HT) receptors
      Grazyna ZYDEK*, Elzbieta BRZEZINSKA (*Dep. of Anal. Chem., Med. Univ. of Lodz, Muszynskiego 1 Street, 90-151 Lódz, Poland)

      J. of Chromatogr. B 879, 1764-1772 (2011). Quantitative structure-activity relationship (QSAR) analysis of 20 drugs with affinity for serotonin (5-HT) receptors by calculation of a set of physicochemical parameters and TLC data. TLC on silica gel and RP-2 impregnated with solutions of aspartic acid, serine, phenylalanine, tryptophan, tyrosine, asparagine, threonine and their mixtures, with two mobile phases - the systems were chosen as models of drug-5-HT-receptor interaction. The relationships between chromatographic data, molecular descriptors and biological activity data were found by regression analysis. The resulting correlations for the compounds with serotoninergic activity represent their interaction with the proposed biochromatographic models. The presented regression models based on biochromatographic studies can be an efficient tool in the QSAR analysis for initial prediction of compounds activity direction within 5-HT receptors.
