Interests in inventing:

  • New, more cost-efficient methods for obtaining nucleic acid components
  • New kinds of application of natural physiologically active substances
     

Key inventions:

  • Phenibut – tranquillizer reducing anxiety, stress and fear, and improving sleep. Interesting enough, this preparation was used before sleep by USSR and USA astronauts during the first linkup of spaceships “Soyuz” and “Apollo”.
  • Orotic acid – a new technology of synthesis. Introduced in 1976 at the Russian chemical and pharmaceutical plant “Akrihin”. The economic gain exceeded 900 thousand roubles. 
  •  ENKADS – the only low-molecular-weight ribonucleotide preparation able to stop deterioration of eyesight and avert eye blindness in cases of inherited retinal dystrophy. The journal “Science” have recognised the discovery that low-molecular-weight ribonucleic acids control most part of the gene activity as the most important scientific achievement of 2002. 
  •  Adenine – it has been discovered that in single-phase synthesis from formamide and phosphorus oxychloride concentration of carbon monoxide plays the determinant role. Similar synthesis of adenine could have taken place in the pre-biological era when the atmosphere of the Earth contained around 17 per cent of carbon monoxide.

Six author’s certificates have been introduced at the Organic synthesis department and nine at the Biochemistry department of Olaine Plant of Chemical Reagents. Production of potassium orotate has been introduced at the chemical and pharmaceutical plant “Akrihin” (Russia).
