DFT and Molecular Docking Study of 1-(2´-Thiophen)-2-propen-1-one-3-(2,3,5-trichlorophenyl) (TTCP) Molecule as Antiviral to Covid-19 Main Protease.

ABSTRACT: Thiophene-containing compounds have antiviral properties and may be among the drugs tested for the treatment of COVID-19 diseases. In order to better understand the molecular definition of the 1-(2´-Thiophen)-2-propen-1-one-3-(2,3,5-trichlorophenyl) molecule from thiophene-containing compounds, the physico-chemical (molecular structure analysis, spectroscopic properties, boundary orbital analysis) mechanisms underlying the protein-ligand interaction should be examined in detail. For this reason, geometric parameters, IR and UV-vis spectra, conformational analysis, electronic, NBO and NLO properties, molecular electrostatic potential map and Mulliken charge distributions of the TTCP molecule were investigated theoretically using DFT theory in the Gaussian program. Accordingly, molecular docking calculations with COVID-19 main protease (PDB 5R7Y) were performed to determine the pharmaceutical activities of the TTCP molecule against coronavirus diseases.

Project description:The recent coronavirus outbreak has changed the world's economy and health sectors due to the high mortality and transmission rates. Because the development of new effective vaccines or treatments against the virus can take time, an urgent need exists for the rapid development and design of new drug candidates to combat this pathogen. Here, we obtained antiviral peptides obtained from the data repository of antimicrobial peptides (DRAMP) and screened their predicted tertiary structures for the ability to inhibit the main protease of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) using multiple combinatorial docking programs, including PatchDock, FireDock, and ClusPro. The four best peptides, DRAMP00877, DRAMP02333, DRAMP02669, and DRAMP03804, had binding energies of -1125.3, -1084.5, -1005.2, and -924.2 Kcal/mol, respectively, as determined using ClusPro, and binding energies of -55.37, -50.96, -49.25, -54.81 Kcal/mol, respectively, as determined using FireDock, which were better binding energy values than observed for other peptide molecules. These peptides were found to bind with the active cavity of the SARS-CoV-2 main protease; at Glu166, Cys145, Asn142, Phe140, and Met165, in addition to the substrate-binding sites, Domain 2 and Domain 3, whereas fewer interactions were observed with Domain 1. The docking studies were further confirmed by a molecular dynamics simulation study, in which several descriptors, including the root-mean-square difference (RMSD), root-mean-square fluctuation (RMSF), solvent-accessible surface area (SASA), radius of gyration (Rg), and hydrogen bond formation, confirmed the stable nature of the peptide-main protease complexes. Toxicity and allergenicity studies confirmed the non-allergenic nature of the peptides. This present study suggests that these identified antiviral peptide molecules might inhibit the main protease of SARS-CoV-2, although further wet-lab experiments remain necessary to verify these findings.
