| heal.abstract | Ternary complexes of formulae [Cu(dipeptide)(nucl)(2)]Cl-2 . xH(2)O with dipeptides glycyl-glycine (Gly-Gly), glycyl-L-alanine (Gly-Ala), glycyl-L-valine (Gly-Val), glycyl-L-leucine (Gly-Leu) and nucl inosine (ino) and guanosine (guo) were isolated from a water:ethanol (2:1) solution and characterized with elemental analysis, conductivity measurements, IR, electronic and ESR spectra. At low pH values (<4) the dipeptides coordinate through the (-NH2) terminal and peptide (C=O) groups and the nucleosides through the N-7 atoms. At pH > 4 the dipeptides coordinate through the (-NH2) terminal and the deprotonated amide (-N-) groups. The pK(a) values for these deprotonations were estimated with electronic spectra and increase with the increase of the side chain of the dipeptides, due to steric reasons. At higher pH values one nucleoside molecule is liberated and replaced by the terminal deprotonated carboxylate group of the dipeptides. The pK values for these transformations were calculated with ESR spectra and follow the same trend as for the deprotonation constants and for the same reason. | en |
