Synthesis, Characterization, and Molecular Docking of Casiopeinas® with Dipeptides as Secondary Ligand; Potential Inhibitors of SARS-Cov-2 Transcendental Proteins
In this work, the synthesis and characterization of fourteen Casiopeinas® are presented, whose general formulae is [Cu(N-N)(L-L)]NO3, where N-N are 2,2´-bipirydine and 1,10-phenanthroline and some of its methylated derivatives, L-L represent the dipeptides L-Tyrosil-Glycinate or Glycil-L-Tyrosinate. Spectroscopic characterization and DFT studies determine the square planar geometry for the coordination compounds, as well as the influence of the dipeptide on the molecular arrangement of ternary copper(II) compounds. In addition, a molecular docking study was carried out against transcendental proteins of the SARS-CoV-2 virus such as main protease (Mpro) and the RBD Spike-ACE2 complex. Docking studies indicate that all compounds can produce stable adducts with Mpro, obtaining ΔGU values (-9.57 to -6.62 Kcal/mol) similar and superior to those presented by the reference inhibitors [boceprevir (-8.44 Kcal/mol) and remdesivir (-6.62 kcal/mol)], while for the RBD Spike-ACE2 complex obtaining ΔGU values of five (-6.69 to -4.61 in C-terminal region) and three (-8.27 to -6.34 in central region) orders of magnitude higher than those presented by the controls (Boceprevir: ΔGU=-1.98 in C-terminal, ΔGU=-4.97 in central region, Remdesivir: ΔGU=Non interactions in C-terminal, ΔGU=-3.37 in central region). π-alkyl interactions, π -cation, π -stacking, as well as hydrogen bonds and salt bridge bonds occur between the proteins and Casiopeinas®. In Mpro, interactions occur in aminoacids that are part of the enzymes catalytic site. Casiopeinas® interact at the interface of the RDB Spike-ACE2 complex in both, C-terminal and central regions. The obtained results position Casiopeinas® as potential candidates protein inhibitors of the virus that causes COVID-19.   Resumen.

期刊介绍: Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
