Abstract
In aqueous and non-aqueous solutions, Cu(II) interacts with the N-3 of cytidine but not with the carbonyl group O of pyrimidine nucleosides. In aqueous solution, Cu(II) interacts with the phosphate group and ribose of pyrimidine nucleotides, and additionally with N-3 of 5''-CMP. Broadening of NMR signals of the H-5 proton of 5''-UMP and C-5 of 5''-UMP and 5''-TMP results probably from the interaction between metal ion and the phosphate group situated in direct vicinity of the above atoms. In the Cu(II)-pyrimidine nucleotide complexes in solid state, Cu is coordinated with the phosphate group, and in 5''-CMP additionally with the pyrimidine moiety of the nucleotide.
