Research: Synthesis, studies of the physicochemical and biological properties of modified nucleosides, nucleotides and DNA/RNA-oligonucleotides containing boron clusters and their complexes with metals, the relationship between the structure and physicochemical and biological properties of modified DNA/RNA-oligonucleotides and their components, modified nucleic acids as new materials for molecular technologies, biotherapeutics, nanomaterials and molecular probes Nucleoside derivatives with antiviral, antitumor and purinergic receptor modulating activity. Boron carriers for boron neutron capture therapy of tumors (BNCT).

Main scientific achievements: development of a new type of nucleic acid analogs modified with boron clusters and their complexes with metals; development of methods for the synthesis of conjugates of purine nucleosides and boron clusters; application of boron clusters, carboranes and metallocarboranes as redox markers for multipotential labeling and electrochemical detection of nucleosides and nucleic acids; development of new type of boron carriers for BNCT; development of the first stereospecific method for the synthesis of phosphorothioate and methanophosphonate analogs of DNA/RNA-oligonucleotides by transesterification method.
