Current research area:

My research included oligonucleotides and their analogues, such as DNA phosphotriesters, oligo(nucleoside phosphorothioate)s, -phosphoroselenoate)s, -phosphoramidate)s and -methanephosphonate)s. Stereoselective synthesis, assignment of absolute configurations at phosphorus, analysis of "tacticity" of oligonucleotide analogues, their interactions with other biopolymers, and search for new effective tools for stereochemical assignments within new, unnatural oligonucleotide constructs, are the continuous goals of research programs performed in the Department of Bioorganic Chemistry. Besides protein engineering, such as h rec αTNF and its muteins (what somehow corresponded with my earlier studies on the synthesis of enantiomeric forms of anti-cancer drugs) my major efforts are directed towards medicinal applications of oligonucleotides and their phosphorothioate and methanephosphonate analogues within antisense-, antigene- and aptameric concepts of inhibition of protein biosynthesis. P-chiral phosphorothioates and isotopomeric phosphates are used as stereochemical probes for investigation of the mechanisms of enzymatic reactions involving phosphodiesterases, phosphoramidases, rybozymes, and others.
