Abstract
In the molecular structure of the title compound, C20H21N3O7, the quinoline ring system is slightly bent, with a dihedral angle between the phenyl and the pyridine rings of 3.47 (7)°. In the crystal, corrugated layers of molecules extending along the ab plane are generated by C—H⋯O hydrogen bonds. The intermolecular interactions were quantified by Hirshfeld surface analysis and two-dimensional fingerprint plots. The most significant contributions to the crystal packing are from H⋯H (42.3%), H⋯O/O⋯H (34.5%) and H⋯C/ C⋯H (17.6%) contacts. Molecular orbital calculations providing electron-density plots of the HOMO and LUMO as well as molecular electrostatic potentials (MEP) were computed, both with the DFT/B3LYP/6–311 G++(d,p) basis set. A molecular docking study between the title molecule and the COVID-19 main protease (PDB ID: 6LU7) was performed, showing that it is a good agent because of its affinity and ability to adhere to the active sites of the protein.
