| Abstract: | Interaction of bivalent (Cu, Ni, Zn, Co, Mg and Ca) metal ions with purine nucleosides (inosine and xanthosine) and amino acids (alanine, phenylalanine and tryptophan) has been investigated by potentiometric pH measurements at 35°C and 0.10 mol dm-3 (KNO3) ionic strength. Extra stabilization has been expressed in terms of  log K values. The stacking interaction observed with different amino acids and nucleosides has been discussed. Further, the influence of exocyclic substituent of xanthosine on-the stabilities is explained. Various parameters have been evaluated to rationalise the stacking interactions. No appreciable interaction is observed with Ca(II) and Mg(II). |
