      G.L. BIAGI*, M.C. GUERRA, A.M. BARBORO, S. BARBIERI, M. RECANATINI, P.A. BOREA, M.C. PIETROGRANDE, (*Inst. Farm., Univ. Bologna, Via Linerio 48, 40126 Bologna, Italy)

      RM and log P values. J. Chromatogr. 498, 179-190 (1990). Measurement of the RM values of a series of xanthine and adenosine derivatives on silicone-impregnated silica and C-18 silica with aqueous glycine buffers (pH 9.0) or sodium acetate veronal buffer (pH 7.0), alone or mixed with various amounts of acetone. Correlation of the two series of data obtained. Comparison of experimental log p values with calculated ones. The TLC data proved to be reliable for describing the lipophilic properties of the test compounds.
