Сurrent Research Activities and Recent Achievements:

Development of low-molecular inhibitors of protein kinase CK2.

In order to discover enzyme inhibitors we have performed screening program, using both in silico and in vitro approaches. AutoDock and DOCK software were used to conduct receptor-ligand flexible docking. The virtual screening experiments were carried out targeting the ATP binding site of protein kinase by searching compound library of about 100,000 compounds. Several hundreds ligands have been selected and taken for the kinase assay study. In vitro experiments allowed us to identify a number of novel classes of CK2 inhibitors – derivatives of (thieno[2,3-d]pyrimidin-4-ylthio)carboxylic acid, 3-carboxyquinoline and 4,5,6,7-tetrahalogeno-1,3-isoindolinedione. Guided by both molecular modeling and SAR analysis chemical optimization of the identified hit compounds allowed us significantly improve their activity and obtain nanomolar and selective CK2 inhibitors. The most active compound inhibiting CK2 belongs to flavonols (IC50=9 nM). This inhibitor was called FLC21 (Fig. 1).

Fig. 1. Chemical structure of the inhibitor FLC21 and its binding mode with the active site of protein kinase CK2
In silico design of ASK1 inhibitors.

We have identified and characterized two classes of ASK1 inhibitors – 3H-naphtho[1,2,3-de]quinoline-2,7-diones and 2-thioxo-thiazolidin-4-ones. Structure-activity relationships of their derivatives have been studied and binding modes of these chemical classes have been predicted. The most perspective inhibitors were called NQDI-1 (IC50=3 μM) and PFTA-1 (IC50=650 nM) (Fig. 2). In our preliminary selectivity studies these compounds exhibited specific inhibitory activity towards ASK1. Compounds NQDI-1 and PFTA-1 demonstrated some cytoprotective effect in HEK293 during apoptosis induced by CHI3L2.

Fig. 2. Chemical structure of the inhibitor PFTA-1 and its binding mode with the active site of protein kinase ASK1
The search for inhibitors of protein kinase FGFR1.

Using virtual screening experiments and in vitro tests we have found several classes of FGFR1 inhibitors: flavones, phenylbenzisoxazoles and aminopyrimidines. Then, we have performed ligand-oriented virtual screening and identified highly active inhibitors from the classes of oxindoles and quinazolines.

The development of new, efficient methods in the field of receptor-oriented high-throughput virtual screening.

We have discovered and parameterized novel method for generating inexpensive and electrostatically reasonable atomic charges of organic compounds. This method is based on the principle of electronegativity relaxation of the Kirchhoff charge model. The new Kirchhoff charges were implemented into a virtual screening engine. To increase accuracy of ligand-receptor interaction energy evaluation the Kirchhoff charges calculation model was used for creating a new force field YFF. This force field is obtained by joining Van-der-Waals and bonded part of well-known MMFF94 with our charge calculation scheme.

Design of fluorescent probes for biomedical applications.

We proposed cyanine dyes for detection of protein aggregation and for studies of globular protein conformational changes. Squaraine dyes have been proposed as efficient noncovalent fluorescent labels for albumins. Series of sensitive fluorescent probes for nonspecific detection of proteins in gels (Lucy506, Lucy569 and Lucy565) were developed by our scientists for Sigma-Aldrich Inc. In collaboration with Sigma-Aldrich we successfully developed novel high-sensitive fluorescent dye Nancy-520 for DNA visualization in gels. The dyes Cyan2 and Cyan40 can provide a highly sensitive method for detection and quantification of non-canonical DNA structures in genome and could be used for the search and development of agents that specifically bind with mentioned DNA motifs and inhibit their functioning (Fig. 3).
