Pyrimidinophanes revealed high extraction selectivity for Ag+ ions and afforded Ag+ mediated duplex-type complexes. Such coordination is realized due to the N1-atoms of the 2-thiocytosine fragments and the polymethylene spacer linking amine groups.

Two-dimensional 1H—15N NMR HSQC/HMBC experiments enable the unambiguous determination of the protonation (methylation) position and tautomeric structure of nitrogen-containing heterocycles. In investigated thiopyrimidines protonation (or methylation) occurs at the N(1) atom of the pyrimidine ring. The tautomeric structures of these compounds were established based on the analysis of 1H—15N NMR spectra. Ab initio calculations of chemical shifts (GIAO B3LYP/6-31G(d)//HF/6-31G) are in full agreement with experimental values. The stability of various protonated (methylated) and tautomeric species is explained in terms of a thermodynamic approach.

Reactions of pyrimidinophanes containing two 6-methylthiocytosine and one 6-methyluracil fragments with methyl p-toluenesulfonate gave amphiphilic macrocyclic bis-p-toluenesulfonates. Despite the presence of several reaction centers in the initial pyrimidinophane molecules, methylation occurred only at the N-1 atom (with quaternization) of the 6-methylthiocytosine fragments. Bacteriostatic and fungistatic activity of the products was estimated.

A series of acyclic and macrocyclic nucleobase derivatives that contain uracil and 2-thiocytosine units linked by polymethylene spacers was prepared. The length of spacers as well as the oxidation number of sulfur atoms entering into the structure of the compounds was varied. The crystal structure of pyrimidinophane with hexa- and heptamethylene linkers was established by X-ray analysis. The metal ion-binding properties of pyrimidinophanes and their acyclic counterparts were investigated by liquid extraction and 1H NMR titration experiments. The compounds with 2-thiocytosine fragments revealed a high selectivity of extraction towards Ag+ ions. The stoichiometry of silver complexes and the binding constants have been determined. The antibacterial activity of these complexes was also discussed.
