Laboratory of biosynthesis of physiologically active compounds

One of the main areas of work is a development of the fundamental and applied aspects of biotechnology for the production of drugs, based on modified nucleoside, for subsequent deployment into biopharmaceuticals production. The other area is a development of biocatalytic technologies of new modified nucleosides for the study of their antiviral and antitumor activities.

1. The biotechnology laboratory has developed and tested technologies for the synthesis of drugs used in modern clinical practice for the treatment of oncohematological diseases:

  • Cladribine is used for as a first and second-line treatment for symptomatic hairy cell leukemia and for B-cell chronic lymphocytic leukemia and is administered by intravenous infusion; Cladribine Tablets (CLARITY) are used for a treatment of multiple sclerosis for patients with relapsing–remitting form of disease.
  • Fludara - B-cell chronic lymphocytic leukemia, non-Hodgkin's lymphoma low grade and follicular B-cell lymphoma and lymphoma cells from the mantle zone (tablet form).
  • Nelarabine - T-cell acute lymphoblastic leukemia and T-cell lymphoblastic lymphoma (in patients with refractory to chemotherapy or recurrent disease).
  • Clofarabine - treatment of acute lymphoblastic leukemia in children older than 1 year with relapse or refractory to therapy after application, at least two previous chemotherapy regimens and in the absence of other ways of achieving sustained remission.

The technologies have been scaled and tested in terms of the pharmaceutical production companies of OAO "Pharmsynthez" (St-Petersburg) and Zao "R-Pharm" (Moscow). The deployment of those technologies on those enterprises is constrained by the need to conduct clinical studies of the substances obtained and the small demand for the RF market (0.5 to 2 kg).

2. Metabolically resistant analogues of the nucleoside antibiotic cordycepin are obtained. Those substances are of great interest for the therapy of African human trypanosomiasis (HAT).

3. Biotechnological approaches to synthesis of pharmaceutical substances of antiviral drugs - ribavirin, vidarabine, didanosine - have been developed.

A convenient approach to the biosynthesis of C2,C6-disubstituted purine nucleosides using E. coli purine nucleoside phosphorylase and arsenolysis

A method of synthesis of new of 3'-deoxyribonucleosides from corresponding ribosides by enzymatic transglycosylation is suggested. It is shown that the use of orthoarsenic acid salts allows to shift the equilibrium of the enzymatic reaction towards the formation of target nucleosides with an efficiency of up to 90% conversion. A scheme of synthesis of 3'-desoxyribose 6-methoxypurine is shown on the figure. In scientific practice arsenates are used exclusively for the degradation of ribo- and deoxyribonucleosides. Only in our laboratory just the second technology in which arsenate is used for highly effective synthesis of new nucleosides is offered.

Manuscript "A convenient approach to the biosynthesis of C2,C6-disubstituted purine nucleosides using E. coli purine nucleoside phosphorylase and arsenolysis» will be published in  Book “Applied Biocatalysis: The Chemist's Enzyme Toolkit”, Fourth Edition, 2020, Publisher Wiley-VCH.
