popup.description1
1. Study the features of proton transfer from cytosine to guanine in a mini-helix with the structure dG5∙dC5.
2. Determine the stability of complexes obtained by high-throughput virtual screening and evaluate their energy parameters.
3. Conduct a large-scale study of the secondary structure of the HIV-1 gene region containing the PBS site in genomes of different subtypes.
popup.description2
The object of research is the structure of nucleic acids and the mechanisms of their interaction with biologically active substances.
Purpose of the work
Search for the complete set of conformational-tautomeric transformations of the A•T pair.
Isolation of the routes responsible for the occurrence of spontaneous point replication errors from among them.
Research methods
The Gaussian 16 modeling software package, the 3DNA software package, the NCBI databases (http://www.ncbi.nlm.nih.gov/) and the HIV sequence database of Los Alamos National Laboratory, (http://www.hiv.lanl.gov/), the UNAFold program.
Results
The experimental and theoretical study confirmed the ability of quercetin and its derivatives to interact with an important antiviral target - RNA polymerase and block its functioning.
