The synthesis of new types of polyhedral and cellular coordination compounds; modeling and experimental study of their antiviral, antitumor and antifibrilogenic activity; creation of «topological drugs» for transcriptional inhibition of enzymes, biochemical and medical samples, antifibrilogenic, antiviral and antitumor compounds, as well as nature-like catalytic systems for the most significant chemical processes and hybrid organo-inorganic and magnetic materials based on these compounds.

Data on the occurrence of clathrochelate chirality caused by their binding to chiral organic molecules and macromolecules of proteins have been obtained. The induced chirality and, accordingly, the appearance of circular dichroism spectra of cellular metal complexes, due to their supramolecular binding to optically active organic molecules and to protein macromolecules, has first been found. Such complexes are promising molecular chiral samples both to establish the macromolecule structure of these proteins and study their conformational transitions.

The first stable «classical» iron(I) complex, which exhibited high chemical stability in strongly acidic environments, has been obtained and structurally characterized.

The methods for obtaining pseudo-macrobicyclic complexes of cobalt with close-borate counterions have been developed. The first high-spin cobalt (II) pseudoclatrochelate with a volumetric closo-borate counterdianion formed by crosslinking with a solvent molecule as an H-acceptor has been obtained. The complex is characterized by a high anisotropy of the magnetic susceptibility tensor and has the properties of a monoionic monomolecular magnet. Its H-bound solvent molecule is subject to substitution under the action of stronger hydrogen bond acceptors. This compound is a promising reactive precursor to create new molecular magnetic materials.

The methods for the synthesis of new hybrid carboranoclatrochelates have been developed. Propargylamine iron(II) clathrochelates have been obtained by means of nucleophilic substitution of chloroclatrochelate precursors under the action of an excess of propargylamine. Their further functionalization using the 1,3-dipolar cycloaddition reaction has resulted in the first hybrid carboranoclatrochelates with a labile spacer fragment between their polyhedral centers.
