Department 3

Department of Bioorganic Reaction Mechanisms

Head of Department - Andriy Vovk, Doctor of Science, Professor, Cor. Member NAS of Ukraine

Areas of scientific activity.

The Department of Bioorganic Reaction Mechanisms (until 2001 - the Department of Photosynthesis Chemistry) was established in 1963 on the basis of the biocatalyst group of the Department of Organic Reaction Mechanisms of the Institute of Organic Chemistry of the Academy of Sciences of Ukraine. Until 1999, the department was headed by Professor, Doctor of Chemical Sciences, Corr. Member NAS of Ukraine O.O. Yasnikov.

Recently, research in the department has focused on elucidating the mechanisms of model bioorganic transformations, synthesizing and studying the properties of new bioactive compounds in model systems, establishing the relationship between their structure and activity, and predicting the bioactivity of organic compounds by the molecularSAR method. The topics of his work are designing inhibitors of non-specific alkaline phosphatases, protein tyrosine phosphatases, acetylcholine cholinesterases, butyrylcholinesterases, lipoxygenases, glutathione-S-transferase, dihydrofolate reductase and other enzymes. The study of antioxidants and new spin probes continues.

Examples of the department's scientific developments (2012–2017)

1. Effective human protein tyrosine phosphatase inhibitors have been found on the platform of calixarenes, fullerenes and cyclic polyamines, which is important for the creation of new drugs for cancer, type 2 diabetes and other diseases.

2. The strategy of constructing non-purine xanthine oxidase inhibitors, which is a therapeutic target in the treatment of gout and hyperuricemia, among mono- and bis-carboxylated derivatives of aurons, is substantiated.

3. The inhibitory capacity of thiazolium salts as potential inhibitors of acetylcholinesterase and tyryl cholinesterase has been established, which creates the basis for further studies of thiazolium derivatives with the aim of finding a cure for Alzheimer's disease.

4. New spin probes and potential antioxidants based on 1-oxyl-2,2,6,6-tetramethylpiperidinyl-4-esters of adamantan- mono- and bis-carboxylic acids have been created.

5. New affinity adsorbents have been developed for the release of thiamine-binding proteins.

6. Among the synthesized 3-alkyloxycarbonylmethyl-4-methyl-5- (2-hydroxyethyl) thiazole salts, the compound 3-decyloxycarbonylmethyl-4-methyl-5- (2-hydroxyethyl) thiazolium chloride is promising for biomedical use.

7. Software for comparing and clustering the active surface of enzymes and proteins has been developed that can be used to select representative conformations of ligand binding centers in the computer simulation process.

8. A modified version of the well-known AutoDock 4.2 software package for molecular docking was created for the purpose of virtual screening of a large number of potential inhibitors. The modification includes a new search engine with a new algorithm that has been specifically designed to work with large size binding centers and mobile ligands, and includes new evaluation features and multithreading.
