RP-TLC retention behavior has been studied for a series of potential antituberculotic drugs from a group of substituted anilides of pyrazine-2-carboxylic acid. Lipophilicity was determined by use of reversed-phase thin-layer chromatography with methanol-water mobile phases. RMW values were obtained by extrapolation of RM (determined by RP-TLC) to methanol-free conditions. These experimental lipophilicity values were correlated with lipophilicity (log P ) calculated by use of three software products. Good correlation was obtained between RMW and log P . The results of this study could be used in further experiments focused on investigation of the biological activity of these newly prepared compounds and other potential antituberculotic drugs with closely similar chemical structures.
