The Effect of Stereochemistry on Sodium Ion Complexation in Nucleoside-Metallacarborane Conjugates
Conjugates of purine and pyrimidine nucleosides: thymidine and 2-deoxyguanosine with cobalt-metallacarborane were studied for their sodium ion complexing properties. Formation of stable complexes of 1 : 1 stoichiometry was proved by ESI MS spectroscopy and 23Na NMR. Equilibrium constants and energi...

| Summary: | Conjugates of purine and pyrimidine nucleosides: thymidine and 2-deoxyguanosine with cobalt-metallacarborane were studied for their sodium ion complexing properties. Formation of stable complexes of 1 : 1 stoichiometry was proved by ESI MS spectroscopy and 23Na NMR. Equilibrium constants and energies of complex formation were calculated. Complexation of alkali-metals by nucleoside-metallacarborane conjugates may affect the physicochemical and biological properties of the conjugates and should be taken into consideration during biological evaluation of these types of modifications. |
