The first example of molecular docking of the SARS-CoV-2 main protease for COVID-19 [Mpro, Protein Data Bank (PDB) code 7BQY] by a chalcone-based ligand, namely, (E)-1-(2,4-dichlorophenyl)-3-[4-(morpholin-4-yl)phenyl]prop-2-en-1-one, C19H17Cl2NO2, I, is presented. Two-dimensional (2D) LIGPLOT representations calculated for the inhibitor N3, viz. N-{[(5-methylisoxazol-3-yl)carbonyl]alanyl}-L-valyl-N 1-((1R,2Z)-4-(benzyloxy)-4-oxo-1-{[(3R)-2-oxopyrrolidin-3-yl]methyl}but-2-enyl)-L-leucinamide, and 7BQY are included for comparison with our chalcone-based complexes. The binding affinity of our chalcone ligand with 7BQY is −7.0 kcal mol−1, a high value which was attributed to the presence of a hydrogen bond, together with many hydrophobic interactions between the drug and the active amino acid residues of the receptor. Docking studies were also performed, employing rigid and flexible binding modes for the ligand. The superposition of N3 and the chalcone docked into the binding pocket of 7BQY is also presented. The synthesis, single-crystal structure, Hirshfeld surface analysis (HSA) and spectral characterization of heterocyclic chalcone-based compound I, are also presented. The molecules are stacked, with normal π–π interactions, in the crystal.
