Abstract
The purposeful development of synthetic antibacterial compounds requires an understanding of the relationship between effects of compounds and their chemical structure. This knowledge can be obtained by studying changes in bacteria ultrastructure under the action of antibacterial compounds of a certain chemical structure. Our study was aimed at examination of ultrastructural changes in S. aureus cells caused by polycationic amphiphile based on 1,4‒diazabicyclo[2.2.2]octane (DL412), ciprofloxacin and their hybrid (DL5Cip6); the samples were incubated for 15 and 45 min. DL412 first directly interacted with bacterial cell wall, damaging it, then penetrated into the cell and disrupted cytoplasm. Ciprofloxacin penetrated into cell without visually damaging the cell wall, but altered the cell membrane and cytoplasm, and inhibited the division of bacteria. The ultrastructural characteristics of S. aureus cells damaged by the hybrid clearly differed from those under ciprofloxacin or DL412 action. Signs associated with ciprofloxacin predominated in cell damage patterns from the hybrid. We studied the effect of ciprofloxacin, DL412 and their hybrid on S. aureus biofilm morphology using paraffin sections. Clear differences in compound effects on S. aureus biofilm (45 min incubation) were observed. The results obtained allow us to recommend this simple and cheap approach for the initial assessment of antibiofilm properties of synthesized compounds.

Abstract
Aptamer selection against novel infections is a complicated and time-consuming approach. Synergy can be achieved by using computational methods together with experimental procedures. This study aims to develop a reliable methodology for a rational aptamer in silico et vitro design. The new approach combines multiple steps: (1) Molecular design, based on screening in a DNA aptamer library and directed mutagenesis to fit the protein tertiary structure; (2) 3D molecular modeling of the target; (3) Molecular docking of an aptamer with the protein; (4) Molecular dynamics (MD) simulations of the complexes; (5) Quantum-mechanical (QM) evaluation of the interactions between aptamer and target with further analysis; (6) Experimental verification at each cycle for structure and binding affinity by using small-angle X-ray scattering, cytometry, and fluorescence polarization. By using a new iterative design procedure, structure- and interaction-based drug design (SIBDD), a highly specific aptamer to the receptor-binding domain of the SARS-CoV-2 spike protein, was developed and validated. The SIBDD approach enhances speed of the high-affinity aptamers development from scratch, using a target protein structure. The method could be used to improve existing aptamers for stronger binding. This approach brings to an advanced level the development of novel affinity probes, functional nucleic acids. It offers a blueprint for the straightforward design of targeting molecules for new pathogen agents and emerging variants.

Abstract
The inhibitory effect of D and L-polynucleotides of a given length (40-50n) on the catalytic activity of DNA polymerase β isolated from chromatin cells of acute myeloid leukemia HL-60 was evaluated. The synthesized L enantiomer was found to have a higher inhibitory activity than the synthesized and isolated D enantiomers of polynucleotides. The work also proposes a biophysical model that describes this effect. The inhibitory activity of L, D-polydeoxyribonucleotides of various compositions was evaluated. Inhibition of DNA polymerase β is due to a nonspecific interaction between the enzyme and the substrate. L-polynucleotide exhibits the highest inhibiting activity, compared to the D-enantiomers.

Abstract
Model DNA molecules that contain bulky lesions in both strands have been created, and their properties as substrates of the nucleotide excision repair (NER) system have been analyzed. The modified nucleoside, 5-[3-(4-azido-2,3,5,6-tetrafluorobenzamido)-1-propoxypropyl]-2'-deoxycytidine (dC^(FAB)), or the nonnucleoside fragment, N-[6-(9-anthracenylcarbamoyl)hexanoyl]-3-amino-1,2-propanediol (nAnt), have been inserted as damage in certain positions of the first DNA strand ("0"). The position of N-[6-5(6)-fluoresceinylcarbamoyl]hexanoyl] -3-amino-1,2-propanediol (nFlu) has been varied within the second DNA strand. This residue has been located opposite the removable damaging fragment of the first strand at positions -20, -10, -4, 0, +3, and +8 relative to the first lesion. It has been demonstrated that the presence of nFlu at the -4, 0, or +3 position of the second strand significantly reduces the thermostability of DNA duplexes, especially in the case of nAnt-DNA and completely excludes the possibility of NER-catalyzed excision from dC^(FAB)- and nAnt-containing 137-meric DNA with the second lesion at these positions. The introduction of nFlu at positions -20, -10, or +8 differently affects the excision efficiency of dC^(FAB)- and nAnt-containing fragments from the first strand. The excision efficiency of dC^(FAB)-containing fragments from extended double-damaged DNA is as high as from DNA that contains a single dC^(FAB) damage, while the excision of nAnt-containing fragments occurs with 80-90% lower efficiency from double-damaged DNA occurs from DNA that contains the single nAnt insert. The nFlu insert differently affects the interaction of the sensory XPC-HR23B dimer with dC^(FAB)- and nAnt-containing DNAs, although in all cases, this interaction occurs with increased efficiency compared to that with single-damaged DNAs. No direct correlation between the thermostability of the DNA duplex and XPC-DNA affinity on the one hand, and the excision efficiency of lesions on the other hand has been shown. The absence of the correlation may be caused by both functional features of variable multiprotein complexes involved in the recognition and verification of damage during NER and the sensitivity of the complexes to the structure of the damage and damage-surrounding DNA. The results are important for understanding the NER mechanism of elimination of bulky damage located in both DNA strands.

Abstract
Artificial ribonucleases (aRNases) are small compounds catalysing RNA cleavage. Recently we demonstrated that aRNases readily inactivate various viruses in vitro. Here, for three series of aRNases (1,4-diazabicyclo [2.2.2]octane-based and peptide-like compounds) we show that apart from ribonuclease activity the aRNases display chaotropic-like and membranolytic activities. The levels of membranolytic and chaotropic-like activities correlate well with the efficiency of various viruses inactivation (enveloped, non-enveloped, RNA-, DNA-containing). We evaluated the impact of these activities on the efficiency of virus inactivation and found: i) the synergism between membranolytic and chaotropic-like activities is sufficient for the inactivation of enveloped viruses (influenza A, encephalitis, vaccinia viruses) for 1,4-diazabicyclo [2.2.2]octane based aRNases, ii) the inactivation of non-enveloped viruses (encephalomyocarditis, acute bee paralysis viruses) is totally dependent on the synergism of chaotropic-like and ribonuclease activities, iii) ribonuclease activity plays a leading role in the inactivation of RNA viruses by aRNases Dp12F6, Dtr12 and K-D-1, iv) peptide-like aRNases (L2-3, K-2) being effective virus killers have a more specific mode of action. Obtained results clearly demonstrate that aRNases represent a new class of broad-spectrum virus-inactivating agents.

Abstract
The dependence of hydrolytic activity of artificial ribonucleases toward an HIV-I RNA fragment, a 21-mer oligonucleotide, and tRNA Asp on the structure of the RNase mimetic was analyzed. The quantitative structure-activity relationship (QSAR task) was determined by the method of simplex representation of the molecular structure where the amounts of four-atom fragments (simplexes) of fixed structure, symmetry, and chirality served as descriptors. Not only the types of atoms participating in simplexes but also their physicochemical properties (e.g., partial charges, lipophilicities, etc.) were taken into account. This allowed the estimation of the relative role of various factors affecting the interaction of molecules under study with the corresponding biological target. The 2D QSAR models obtained by the method of projection to latent structures have quite satisfactory statistical indices (R2 = 0.82-0.96; Q2 = 0.73-0.89), which help predict the activities of new compounds. The electrostatic properties of ribonuclease atoms were shown to contribute significantly to the manifestation of the hydrolytic activity of ribonucleases in the case of the 21-mer oligonucleotide and tRNA. In addition, the structural fragments that most greatly contribute to the alteration of the hydrolytic activity of RNases were identified. The models obtained were used for the virtual screening and molecular design of new highly efficient RNase mimetics.

Abstract
Artificial ribonucleases of A(n)BCL series were synthesized by solid-phase method. They consist of a hydrophobic alkyl radical A (n = 3-12 carbon atoms), an "RNA-binding domain" B (bisquaternary salt of 1,4-diazabicyclo[2.2.2]octane), a "catalytic domain" C (histidine residue) and a "linker" L that joins the domains B and C. The effect of the alkyl radical on the catalytic properties of the chemical catalyst was studied using three activated phosphate ester substrates: p-nitrophenyl phosphate, bis-p-nitrophenyl phosphate, and thymidine-3'-p-nitrophenyl phosphate.
