Four nonnatural imidazole nucleosides with different substituents were synthesized and studied for their binding to a CGWatson-Crickbasepair by NMR spectroscopic techniques in an aprotic solvent. Concentration and temperature dependent measurements allowed the determination of association constants, association enthalpies and entropies. Strong binding was observed with analogues carrying an ureidophenyl

Novel imidazole nucleosides with substituents of different flexibility were studied for their binding to a CGWatson−Crickbasepair by 1H NMR spectroscopy in an aprotic solvent. Thermodynamic data as determined by titration experiments at different temperatures reveal the influence of the substituent on the enthalpy and entropy of complex formation and thus on the strength of binding.
